1
00:00:00,800 --> 00:00:03,760
Speaker 1: Hey, everybody, we're coming to the Pacific Northwest. So if

2
00:00:03,800 --> 00:00:06,000
Speaker 1: you live in that area or can get on a

3
00:00:06,040 --> 00:00:07,840
Speaker 1: plane to go to that area, or a boat or

4
00:00:07,920 --> 00:00:11,320
Speaker 1: snowshoe whatever, we'll see you at the end of January.

5
00:00:11,680 --> 00:00:14,160
Speaker 2: That's right, brand new show, brand new topic. We don't

6
00:00:14,160 --> 00:00:16,200
Speaker 2: even know what it is yet, but we'll be in Seattle,

7
00:00:16,280 --> 00:00:20,640
Speaker 2: Washington on January twenty fourth, Portland on January twenty fifth,

8
00:00:20,920 --> 00:00:24,440
Speaker 2: and then our annual trip to San Francisco's Sketch Fest

9
00:00:24,720 --> 00:00:27,800
Speaker 2: on January twenty sixth in Seattle. We're counting on you.

10
00:00:28,080 --> 00:00:29,880
Speaker 2: We're at the Paramount this year and that's a lot

11
00:00:29,960 --> 00:00:31,760
Speaker 2: of seats, so we need a lot of your lovely

12
00:00:31,800 --> 00:00:32,800

Speaker 1: see you guys in January. We can't wait.

18
00:00:48,080 --> 00:00:54,360
Speaker 3: Welcome to Stuff You Should Know, a production of iHeartRadio.

19
00:00:57,760 --> 00:01:00,600
Speaker 1: Hey, and welcome to the podcast. I'm Josh Chuck and

20
00:01:00,680 --> 00:01:03,360
Speaker 1: Jerry's here too, and this is Stuff you Should Know.

21
00:01:04,760 --> 00:01:05,720
Speaker 1: The Tanka edition.

22
00:01:07,040 --> 00:01:10,080
Speaker 2: M you know, I had a terrible thought earlier that

23
00:01:10,160 --> 00:01:15,720
Speaker 2: it might be fun to release this episode on cranes

24
00:01:16,000 --> 00:01:19,720
Speaker 2: and then one of the bird cranes, and then we

25
00:01:19,800 --> 00:01:22,880
Speaker 2: have another one coming up that I just you know,

26
00:01:23,000 --> 00:01:26,440
Speaker 2: asked our friend Dave Ruse to get on that. Could

27
00:01:26,560 --> 00:01:28,280
Speaker 2: we could also do you know that one is? Did

28
00:01:28,319 --> 00:01:30,360
Speaker 2: you see that? I don't want to give it away.

29
00:01:30,880 --> 00:01:34,480
Speaker 2: It's also a food in a cartoon. I don't We

30
00:01:34,480 --> 00:01:36,360
Speaker 2: could do one on the food in the cartoon with

31
00:01:36,400 --> 00:01:39,119
Speaker 2: the same title, and we should just start doing even

32
00:01:39,160 --> 00:01:40,280
Speaker 2: more confusing titles.

33
00:01:40,560 --> 00:01:42,199
Speaker 1: Okay, I think that's a great idea.

34
00:01:43,160 --> 00:01:45,199
Speaker 3: So we got to do one on the bird cranes next.

35
00:01:45,400 --> 00:01:47,840
Speaker 1: Okay, so and we'll just title them the same thing.

36
00:01:48,440 --> 00:01:53,520
Speaker 2: Yeah, okay, how cranes work. How cranes work. Figure, people

37
00:01:53,520 --> 00:01:55,480
Speaker 2: won't know what they're because that happens a lot anyway.

38
00:01:55,520 --> 00:01:58,320
Speaker 2: Like when we did Nirvana, we actually put not the

39
00:01:58,360 --> 00:01:59,240
Speaker 2: band right.

40
00:01:59,320 --> 00:02:02,520
Speaker 1: Right, That was the opposite of being purposely confusing.

41
00:02:02,880 --> 00:02:03,560
Speaker 3: Yeah, exactly.

42
00:02:03,960 --> 00:02:06,760
Speaker 1: Today in this episode a couple of minutes in now

43
00:02:06,800 --> 00:02:10,320
Speaker 1: we'll finally reveal we're talking about the construction version of Cranes.

44
00:02:10,960 --> 00:02:11,560
Speaker 3: That's right.

45
00:02:12,080 --> 00:02:14,239
Speaker 1: Yeah, that's why I said the Tonka edition, which is

46
00:02:14,280 --> 00:02:17,000
Speaker 1: probably a bit of a giveaway. Were you into Tonka?

47
00:02:17,680 --> 00:02:19,880
Speaker 3: I wasn't that into Tonka.

48
00:02:19,960 --> 00:02:20,240
Speaker 1: Okay.

49
00:02:20,280 --> 00:02:22,040
Speaker 2: I think I had a truck or something, but I wasn't.

50
00:02:22,520 --> 00:02:24,680
Speaker 2: I was a sensitive boy. I wasn't banging trucks around

51
00:02:24,680 --> 00:02:25,360
Speaker 2: and building things.

52
00:02:25,400 --> 00:02:26,000
Speaker 1: I was too.

53
00:02:29,400 --> 00:02:31,800
Speaker 2: I also feel like we've gone back in time because

54
00:02:31,840 --> 00:02:34,080
Speaker 2: this feels like a very ten years ago thing for us.

55
00:02:35,200 --> 00:02:37,840
Speaker 1: Oh yeah, the article on the House of Work site

56
00:02:37,880 --> 00:02:42,520
Speaker 1: was written by Marshall Brain himself. Oh but mister Ruse

57
00:02:42,520 --> 00:02:43,640
Speaker 1: helps us out with this one.

58
00:02:44,200 --> 00:02:45,799
Speaker 3: Yeah, okay, was that the deal?

59
00:02:47,200 --> 00:02:49,760
Speaker 1: No, it wasn't. I actually didn't know that there was something.

60
00:02:49,800 --> 00:02:52,360
Speaker 1: I was looking up some fact or whatever and that

61
00:02:52,560 --> 00:02:54,840
Speaker 1: article came up and I was like, oh, oh okay,

62
00:02:54,919 --> 00:03:00,440
Speaker 1: So yeah, no, that wasn't the deal. But I don't

63
00:03:00,480 --> 00:03:02,240
Speaker 1: remember what made me want to do this.

64
00:03:02,320 --> 00:03:04,760
Speaker 3: I think it was just probably saw one. Huh.

65
00:03:04,800 --> 00:03:08,280
Speaker 1: I don't think so. I mean, I've seen plenty, but no,

66
00:03:08,680 --> 00:03:10,880
Speaker 1: I really don't think that's what did it. I don't

67
00:03:10,919 --> 00:03:12,600
Speaker 1: know where it came from, but I think it's just

68
00:03:12,720 --> 00:03:15,280
Speaker 1: kind of like a lifelong fascination with it. Like I'm

69
00:03:16,000 --> 00:03:18,280
Speaker 1: not like a crane aphile or anything like that. I

70
00:03:18,280 --> 00:03:20,919
Speaker 1: can't tell you, like, you know, the names of the operators.

71
00:03:20,919 --> 00:03:24,200
Speaker 1: I don't have like trading cards or anything. But I

72
00:03:24,240 --> 00:03:29,639
Speaker 1: do find construction stuff pretty impressive from like a distance,

73
00:03:30,040 --> 00:03:30,720
Speaker 1: you know what I mean.

74
00:03:30,600 --> 00:03:32,440
Speaker 3: Totally, Yeah, you see the people.

75
00:03:33,000 --> 00:03:36,160
Speaker 2: Yeah, when I see one of those things going, I

76
00:03:36,200 --> 00:03:38,600
Speaker 2: always stop and take a look and just think, my lord,

77
00:03:38,720 --> 00:03:40,200
Speaker 2: what have we come up with now?

78
00:03:40,400 --> 00:03:42,520
Speaker 1: Yeah, and we should say there's a ton of different cranes.

79
00:03:42,560 --> 00:03:45,480
Speaker 1: So this is specifically tower cranes. And we didn't call

80
00:03:45,520 --> 00:03:49,400
Speaker 1: the episode that just because apparently we're going to confuse everybody.

81
00:03:49,760 --> 00:03:52,440
Speaker 1: No tower cranes would have given it away. But we're

82
00:03:52,440 --> 00:03:54,480
Speaker 1: talking about a very specific kind of crane, and it

83
00:03:54,560 --> 00:03:57,400
Speaker 1: is the construction crane, the kind you see on construction sites,

84
00:03:57,720 --> 00:04:00,200
Speaker 1: especially these days if you're driving through toront know.

85
00:04:01,440 --> 00:04:05,120
Speaker 2: Yeah, apparently Dave dug up some stats on crane usage.

86
00:04:05,120 --> 00:04:06,240
Speaker 3: Who knew that existed?

87
00:04:07,080 --> 00:04:11,880
Speaker 2: And Toronto right now leads the way in North America

88
00:04:11,960 --> 00:04:14,360
Speaker 2: with the most operating cranes. I guess they're building a

89
00:04:14,400 --> 00:04:17,360
Speaker 2: lot there. Yeah, they've got one hundred and twenty one going.

90
00:04:17,960 --> 00:04:22,839
Speaker 2: But one boy in the twenty tens he found that

91
00:04:22,920 --> 00:04:26,120
Speaker 2: there were about one hundred thousand cranes operating around the

92
00:04:26,120 --> 00:04:29,359
Speaker 2: world during that big you know, twenty tens construction boom.

93
00:04:29,480 --> 00:04:32,080
Speaker 1: Yeah, and I mean that's a really good proxy for

94
00:04:32,279 --> 00:04:36,200
Speaker 1: how the global construction industry is doing, because I guess

95
00:04:36,240 --> 00:04:41,200
Speaker 1: I think you essentially can't undertake any decent sized construction

96
00:04:41,320 --> 00:04:45,799
Speaker 1: project without a tower crane of some sort on your site.

97
00:04:46,320 --> 00:04:48,920
Speaker 3: Yeah, if you want height, you're gonna need a crane.

98
00:04:49,240 --> 00:04:51,599
Speaker 1: Yeah, you want height, you want to very quickly and

99
00:04:51,640 --> 00:04:55,880
Speaker 1: easily move like a pile of you know, steel girders

100
00:04:55,960 --> 00:04:59,880
Speaker 1: or rebar like, Yeah, you can break down that bunch

101
00:04:59,880 --> 00:05:01,920
Speaker 1: of rebar and have a bunch of guys just kind

102
00:05:01,960 --> 00:05:03,839
Speaker 1: of card it from one side to the other, or

103
00:05:04,279 --> 00:05:07,520
Speaker 1: you can save about twenty man hours and just lift

104
00:05:07,560 --> 00:05:09,520
Speaker 1: it up and move it over with the crane. They're

105
00:05:09,640 --> 00:05:12,239
Speaker 1: they're invaluable for a construction site.

106
00:05:13,000 --> 00:05:13,320
Speaker 3: They are.

107
00:05:13,400 --> 00:05:15,880
Speaker 2: And he also found this cool stat which is the

108
00:05:15,960 --> 00:05:20,040
Speaker 2: largest one going right now from I don't know how

109
00:05:20,040 --> 00:05:23,200
Speaker 2: to say that Kroll cranes that oh has a null set.

110
00:05:23,360 --> 00:05:27,279
Speaker 2: It's Danish, so yeah, some some Danish pronunciation crue. But

111
00:05:27,960 --> 00:05:31,240
Speaker 2: the K ten thousand, my friend, as you know and

112
00:05:31,279 --> 00:05:35,080
Speaker 2: my friends out there listening, that can lift about one

113
00:05:35,160 --> 00:05:39,080
Speaker 2: hundred SUVs five hundred and twenty eight thousand pounds, Yeah,

114
00:05:39,320 --> 00:05:42,760
Speaker 2: and like one hundred SUVs. Yeah, not like escapes either,

115
00:05:42,839 --> 00:05:45,839
Speaker 2: like normal sized SUVs.

116
00:05:45,720 --> 00:05:48,280
Speaker 3: At googleed like mid sized fall bo asuv bit.

117
00:05:49,320 --> 00:05:51,920
Speaker 1: Yeah, it makes sense. It's a lot of SUVs all

118
00:05:51,960 --> 00:05:54,960
Speaker 1: at once that it could lift up. And that's as

119
00:05:54,960 --> 00:05:57,560
Speaker 1: we'll see. It depends on where it's lifting from and

120
00:05:57,600 --> 00:06:00,640
Speaker 1: all that. There's a lot of a lot of variables

121
00:06:00,640 --> 00:06:04,120
Speaker 1: and factors, and all of that put together, combined with

122
00:06:04,240 --> 00:06:09,320
Speaker 1: the danger and just the unique situation anybody who's operating

123
00:06:09,320 --> 00:06:14,919
Speaker 1: a crane is in, makes it a really demanding, high

124
00:06:14,920 --> 00:06:19,440
Speaker 1: pressure job. I saw one crane operator basically liking it

125
00:06:19,440 --> 00:06:23,400
Speaker 1: to eight hours of NonStop surgery essentially because of the

126
00:06:24,160 --> 00:06:26,839
Speaker 1: attention to detail you have to have at all times.

127
00:06:27,200 --> 00:06:29,320
Speaker 1: You have to anticipate what people on the ground are

128
00:06:29,400 --> 00:06:32,240
Speaker 1: going to do based on the body movement. And you're

129
00:06:32,279 --> 00:06:35,839
Speaker 1: working with your hands like you use two joysticks and

130
00:06:35,880 --> 00:06:39,440
Speaker 1: it seems very simple, but you can make the crane

131
00:06:39,480 --> 00:06:42,280
Speaker 1: do all sorts of interesting things with just those two joysticks.

132
00:06:42,600 --> 00:06:45,520
Speaker 1: And depending on how busy the construction site is, you

133
00:06:45,640 --> 00:06:49,200
Speaker 1: might not stop moving those joysticks essentially the entire day.

134
00:06:49,760 --> 00:06:54,400
Speaker 2: Yeah, all sorts of things. How about a solfshoe. Sure, yeah,

135
00:06:54,400 --> 00:06:59,000
Speaker 2: it's like a battle zone. Remember that game No Battles.

136
00:06:59,080 --> 00:07:00,800
Speaker 2: I think we even talked about this. That's the one

137
00:07:00,839 --> 00:07:03,960
Speaker 2: where you look through the arcade game where it was

138
00:07:04,000 --> 00:07:08,000
Speaker 2: made out of like green what's it called when it's

139
00:07:08,040 --> 00:07:10,400
Speaker 2: just lined out and not colored in like a vector

140
00:07:11,160 --> 00:07:13,080
Speaker 2: like a yeah, sort of, and you had a left

141
00:07:13,080 --> 00:07:15,800
Speaker 2: and right joystick like you were driving a tank around, okay,

142
00:07:15,880 --> 00:07:18,080
Speaker 2: and looking and looking through an eyepiece.

143
00:07:17,800 --> 00:07:20,000
Speaker 1: Yes, I remember now. And then that made me talk

144
00:07:20,040 --> 00:07:25,360
Speaker 1: about Sea Wolf. I think the Paris game basically yeah,

145
00:07:25,960 --> 00:07:26,480
Speaker 1: all right.

146
00:07:26,480 --> 00:07:29,600
Speaker 3: Yeah, but you can move on from market, yeah, exactly.

147
00:07:29,920 --> 00:07:36,040
Speaker 1: It's kind of like that, but with real death involved potentially, right.

148
00:07:37,280 --> 00:07:40,520
Speaker 2: And this whole thing was the idea of a German

149
00:07:40,640 --> 00:07:47,360
Speaker 2: construction engineer post World War two named Hans Liba, because

150
00:07:47,480 --> 00:07:50,280
Speaker 2: Hans Liba had a lot of Germany and all of

151
00:07:50,280 --> 00:07:52,400
Speaker 2: Germany had a lot of Germany to rebuild, especially in

152
00:07:52,400 --> 00:07:55,280
Speaker 2: the city centers. Yeah, post World War two, and so

153
00:07:55,400 --> 00:07:57,560
Speaker 2: he came up with this idea in nineteen forty nine

154
00:07:58,040 --> 00:08:00,440
Speaker 2: of a mobile tower crane that you could you know,

155
00:08:00,520 --> 00:08:04,160
Speaker 2: take from place to place. What you would say now,

156
00:08:04,200 --> 00:08:07,040
Speaker 2: it was probably what we would call a luffing crane

157
00:08:07,080 --> 00:08:09,960
Speaker 2: of the UFFI and G which we'll talk about a

158
00:08:09,960 --> 00:08:12,760
Speaker 2: little bit later on when we're detailing cranes. So not

159
00:08:12,880 --> 00:08:15,080
Speaker 2: that you know the hugest, super tall ones, but it

160
00:08:15,160 --> 00:08:16,840
Speaker 2: was nineteen forty nine. It was a good start.

161
00:08:17,240 --> 00:08:20,520
Speaker 1: Yeah, I mean, give liber a break, Like he's the

162
00:08:20,520 --> 00:08:22,720
Speaker 1: one who essentially said, like, we need cranes, and we

163
00:08:22,720 --> 00:08:25,400
Speaker 1: can do more with cranes, like there would not be

164
00:08:25,440 --> 00:08:31,080
Speaker 1: skyscrapers without tower cranes. Sorry, face it. Yeah, and also

165
00:08:31,160 --> 00:08:32,800
Speaker 1: we should probably give them their due. It goes all

166
00:08:32,800 --> 00:08:36,080
Speaker 1: the way back to at the very least the sixth

167
00:08:36,080 --> 00:08:38,520
Speaker 1: century BCE Greeks, who were the first ones to start

168
00:08:38,600 --> 00:08:43,920
Speaker 1: using cranes and construction projects. Yeah, so basically nothing happened

169
00:08:43,960 --> 00:08:48,800
Speaker 1: for twenty six hundred years roughly until Hans Lieber came along.

170
00:08:49,640 --> 00:08:52,120
Speaker 2: These climbing cranes were going to detail came about in

171
00:08:52,160 --> 00:08:55,800
Speaker 2: the nineteen sixties thanks to and these things are pretty remarkable.

172
00:08:55,840 --> 00:08:58,080
Speaker 2: That's the really giant tall ones that you see that

173
00:08:58,640 --> 00:09:02,880
Speaker 2: kind of build themselves and boy, just stick around everybody

174
00:09:03,000 --> 00:09:06,640
Speaker 2: because it gets pretty hot. But they were came to

175
00:09:06,679 --> 00:09:09,960
Speaker 2: his courtesy of a couple of Ozzie brothers Ted and

176
00:09:10,200 --> 00:09:14,920
Speaker 2: Eric Favell, I guess in nineteen sixty two. And because

177
00:09:14,960 --> 00:09:18,880
Speaker 2: they were Australian, of course, they called them kangaroo jumping cranes.

178
00:09:19,920 --> 00:09:23,760
Speaker 1: Like for real, I'll bet everyone but the Australians called

179
00:09:23,760 --> 00:09:24,000
Speaker 1: it that.

180
00:09:25,240 --> 00:09:28,400
Speaker 2: Maybe so, but they helped to erect the Twin Towers

181
00:09:28,400 --> 00:09:29,120
Speaker 2: in New York City.

182
00:09:29,600 --> 00:09:32,240
Speaker 1: Yeah, apparently so did the K ten thousand from what

183
00:09:32,320 --> 00:09:33,040
Speaker 1: I understand.

184
00:09:33,760 --> 00:09:35,199
Speaker 3: Oh, so that one's been around. Huh.

185
00:09:35,280 --> 00:09:37,120
Speaker 1: Yeah. I think a lot of cranes helped build the

186
00:09:37,200 --> 00:09:40,920
Speaker 1: Twin Towers. But you couldn't have built the Twin Towers

187
00:09:40,920 --> 00:09:45,640
Speaker 1: without climbing cranes. And like you said, man, well, if

188
00:09:45,679 --> 00:09:49,240
Speaker 1: you understand how the climbing cranes work, they're just it's amazing.

189
00:09:49,280 --> 00:09:51,720
Speaker 1: But it also answers a really great question, like how

190
00:09:51,720 --> 00:09:53,960
Speaker 1: did those little cranes get all the way on top

191
00:09:54,040 --> 00:09:58,720
Speaker 1: of a skyscraper? Just wait, just you wait, the eight

192
00:09:58,800 --> 00:09:59,839
Speaker 1: year old kid in all.

193
00:10:01,840 --> 00:10:03,800
Speaker 2: But we're going to be mainly talking about what's known

194
00:10:03,840 --> 00:10:06,320
Speaker 2: as a hammerhead tower crane, and that is when you

195
00:10:06,360 --> 00:10:09,680
Speaker 2: look up in the sky and you see a giant,

196
00:10:09,720 --> 00:10:15,720
Speaker 2: giant tall tea, essentially with a very long side of

197
00:10:15,760 --> 00:10:19,000
Speaker 2: that tea horizontal tea and a shorter side coming out

198
00:10:19,000 --> 00:10:20,240
Speaker 2: the other side of the tea.

199
00:10:20,360 --> 00:10:22,959
Speaker 1: It's like an inexpertly written tea.

200
00:10:23,880 --> 00:10:25,480
Speaker 3: It looks like one of my daughter's teas.

201
00:10:25,679 --> 00:10:28,600
Speaker 1: Okay, well, I would call her inexpert at this point,

202
00:10:28,640 --> 00:10:29,600
Speaker 1: she's just starting out.

203
00:10:30,320 --> 00:10:32,640
Speaker 3: Yeah, her penmanship is terrible. We're working on it.

204
00:10:33,440 --> 00:10:35,959
Speaker 1: Just teach her how to cut letters out of magazines.

205
00:10:36,360 --> 00:10:37,520
Speaker 3: We were, yeah, I should.

206
00:10:37,559 --> 00:10:39,240
Speaker 2: We were working on her math last night and she

207
00:10:39,320 --> 00:10:42,040
Speaker 2: was having me check her actual math work and I said, your.

208
00:10:41,920 --> 00:10:43,000
Speaker 3: Math is all perfect.

209
00:10:43,280 --> 00:10:46,040
Speaker 2: I said, I'd like to see work on just sort

210
00:10:46,080 --> 00:10:48,480
Speaker 2: of the neatness in how you display your answers. She

211
00:10:48,559 --> 00:10:50,760
Speaker 2: was like, what it's like, Well, you know, I can

212
00:10:51,040 --> 00:10:53,000
Speaker 2: look at this. I was kind of pointing things out

213
00:10:53,000 --> 00:10:56,280
Speaker 2: in a very Larry David kind of way, so I'm

214
00:10:56,320 --> 00:10:57,160
Speaker 2: not sure if it's sunk in.

215
00:10:57,200 --> 00:10:57,640
Speaker 3: We'll see.

216
00:10:57,760 --> 00:10:59,280
Speaker 1: Did she get the curb references?

217
00:11:00,080 --> 00:11:03,160
Speaker 3: Oh, she totally did. Jeff Garland's your favorite.

218
00:11:03,960 --> 00:11:07,559
Speaker 1: So all right, well, let's talk about the components of

219
00:11:07,600 --> 00:11:13,720
Speaker 1: a crane, because it's actually extraordinarily simple. It's extraordinarily it's

220
00:11:13,720 --> 00:11:16,240
Speaker 1: just as it's just as easy as that. They're really

221
00:11:16,360 --> 00:11:22,000
Speaker 1: simple machines, but they're intricate in how precise they need

222
00:11:22,040 --> 00:11:22,280
Speaker 1: to be.

223
00:11:23,280 --> 00:11:26,199
Speaker 2: Yeah, so we gotta start. Let's go bottom up. You

224
00:11:26,200 --> 00:11:27,000
Speaker 2: want to go bottom up?

225
00:11:29,920 --> 00:11:31,520
Speaker 1: Okay, yeah, that seems all right.

226
00:11:32,320 --> 00:11:34,080
Speaker 2: All right, Well, we got to start with a foundation

227
00:11:34,240 --> 00:11:37,800
Speaker 2: because obviously, if something is this tall and they're you know,

228
00:11:37,880 --> 00:11:42,000
Speaker 2: lifting things like one hundred SUVs, basically you're going to

229
00:11:42,080 --> 00:11:44,640
Speaker 2: have to have a heck of a foundation and that's

230
00:11:44,640 --> 00:11:47,000
Speaker 2: where you're going to start. These things are actually sunk

231
00:11:47,480 --> 00:11:51,640
Speaker 2: into a concrete pad. The concrete pad for the largest

232
00:11:51,679 --> 00:11:55,920
Speaker 2: ones weighs about four hundred thousand pounds, and it is

233
00:11:56,040 --> 00:11:58,160
Speaker 2: it's not like they do this in blocks and sections.

234
00:11:58,160 --> 00:12:02,840
Speaker 2: It's one big long con crete pour through rebar to

235
00:12:03,040 --> 00:12:05,800
Speaker 2: just make that thing as solid as it was built

236
00:12:05,800 --> 00:12:07,559
Speaker 2: into the actual bedrock of the earth.

237
00:12:07,640 --> 00:12:11,280
Speaker 1: Yeah. They essentially are creating their own bedrock to pour around.

238
00:12:11,280 --> 00:12:14,600
Speaker 1: The foundation of the mast is what it's called. That

239
00:12:14,679 --> 00:12:17,480
Speaker 1: part of the crane that rises upward from the ground.

240
00:12:18,120 --> 00:12:21,000
Speaker 1: That's called the tower or the mast, and the bottom

241
00:12:21,040 --> 00:12:26,680
Speaker 1: of the mast is cemented into an enormous multi hundred

242
00:12:26,720 --> 00:12:30,560
Speaker 1: thousand pounds block of concrete. It's pretty impressive in and

243
00:12:30,600 --> 00:12:34,360
Speaker 1: of itself, right totally, So the mast, you might if

244
00:12:34,400 --> 00:12:38,320
Speaker 1: you look closely, you'll see it's made of essentially trusses,

245
00:12:38,360 --> 00:12:41,280
Speaker 1: squares and trusses. And if you will refer to our

246
00:12:41,320 --> 00:12:45,160
Speaker 1: Bridges episode, we came face to face with the realization

247
00:12:45,280 --> 00:12:50,560
Speaker 1: that trustes are the most beautifully strong structure on Earth essentially.

248
00:12:51,120 --> 00:12:54,520
Speaker 1: So it makes sense because as we'll see, you want

249
00:12:54,559 --> 00:13:01,000
Speaker 1: these the mast sections to be fairly lightweight, and you

250
00:13:01,040 --> 00:13:04,960
Speaker 1: can make something lightweight if you use trusses. So I'm

251
00:13:05,040 --> 00:13:07,880
Speaker 1: sure it was Hans Leber who figured that one out,

252
00:13:07,920 --> 00:13:08,880
Speaker 1: like right out of the gate.

253
00:13:09,640 --> 00:13:14,160
Speaker 2: Yeah, absolutely, depending on you know your project, is how

254
00:13:14,200 --> 00:13:17,000
Speaker 2: tall your tower is going to be, because like you said,

255
00:13:17,040 --> 00:13:20,440
Speaker 2: they well you'll see how they build themselves. But you

256
00:13:20,480 --> 00:13:22,400
Speaker 2: don't want one that's taller than it needs to be,

257
00:13:22,840 --> 00:13:25,520
Speaker 2: and obviously you want it tall enough. The tallest ones

258
00:13:25,520 --> 00:13:30,640
Speaker 2: are over four hundred feet tall, and the more standard

259
00:13:30,640 --> 00:13:33,360
Speaker 2: wins are and then like two hundred and fifty foot range.

260
00:13:33,160 --> 00:13:36,080
Speaker 1: Right, I guess that with a K ten thousand, and

261
00:13:36,120 --> 00:13:39,800
Speaker 1: I think some I think China just released like the

262
00:13:39,920 --> 00:13:44,320
Speaker 1: largest toughest crane around. It's a real competitor to the

263
00:13:44,720 --> 00:13:48,040
Speaker 1: K ten thousand. Button surprised me anything over about four

264
00:13:48,120 --> 00:13:51,679
Speaker 1: hundred feet. We haven't really cracked the physics of a

265
00:13:51,720 --> 00:13:55,840
Speaker 1: free standing tower crane. Beyond that, it just it's too unstable,

266
00:13:55,880 --> 00:14:00,640
Speaker 1: it's too risky, it doesn't work. So let's say we

267
00:14:00,679 --> 00:14:02,880
Speaker 1: top out at about two hundred and two fifty I

268
00:14:02,920 --> 00:14:03,959
Speaker 1: think you said something like.

269
00:14:03,920 --> 00:14:06,040
Speaker 3: That, Yeah, two fifty ish.

270
00:14:06,400 --> 00:14:09,440
Speaker 1: The top I don't know. Ten percent of that probably

271
00:14:09,800 --> 00:14:12,920
Speaker 1: would be made up of what's called the cat's head.

272
00:14:13,360 --> 00:14:16,520
Speaker 1: And the cat's head is essentially the top of the

273
00:14:16,559 --> 00:14:20,160
Speaker 1: crane that all of the parts that actually do the

274
00:14:20,240 --> 00:14:25,040
Speaker 1: work above the mast connect to. Okay, yeah, So for example,

275
00:14:25,080 --> 00:14:28,960
Speaker 1: you have the slewing unit, and the slewing unit is

276
00:14:29,760 --> 00:14:32,200
Speaker 1: at the neck basically the base of the head of

277
00:14:32,240 --> 00:14:35,880
Speaker 1: that cat's head, and it's essentially a huge disk that

278
00:14:36,240 --> 00:14:38,760
Speaker 1: the whole thing can spin around on three hundred and

279
00:14:38,800 --> 00:14:42,880
Speaker 1: sixty Degrease, go buy a work site tower crane. Shout

280
00:14:42,960 --> 00:14:45,560
Speaker 1: up to him, say do me a three sixty. Any

281
00:14:45,600 --> 00:14:47,800
Speaker 1: crane operator worth their salt will just stop what they're

282
00:14:47,800 --> 00:14:49,720
Speaker 1: doing and do a three sixty for you to show

283
00:14:50,120 --> 00:14:51,960
Speaker 1: just how amazing the slewing unit is.

284
00:14:52,880 --> 00:14:55,440
Speaker 3: Uh. Did you know what the definition of slew is?

285
00:14:56,360 --> 00:14:59,480
Speaker 1: Uh? Does it have something to do with seattle?

286
00:15:00,600 --> 00:15:06,560
Speaker 2: No, it's to turn violently or uncontrollably. No, yeah, that's

287
00:15:06,560 --> 00:15:11,880
Speaker 2: what the verb is, you know, undergoing slewing, or as

288
00:15:11,880 --> 00:15:15,320
Speaker 2: a noun a violent or uncontrollable sliding movement.

289
00:15:15,600 --> 00:15:19,200
Speaker 1: Chuck, I tip my Breton cap to you for looking

290
00:15:19,280 --> 00:15:21,880
Speaker 1: up that word in year fifteen. Man, way to go.

291
00:15:22,000 --> 00:15:25,400
Speaker 2: Well, I didn't know what it meant, so I appreciate that.

292
00:15:25,480 --> 00:15:28,280
Speaker 2: But it's just I don't know. I'm sure someone can

293
00:15:28,320 --> 00:15:28,840
Speaker 2: explain this.

294
00:15:29,000 --> 00:15:31,120
Speaker 3: Boy. I'm hoping we hear from crane people.

295
00:15:31,280 --> 00:15:31,480
Speaker 2: Oh.

296
00:15:31,520 --> 00:15:33,360
Speaker 1: I hope so too, And I hope they're like, gosh,

297
00:15:33,360 --> 00:15:36,120
Speaker 1: you guys sure got it right, Not like I'm never listening.

298
00:15:35,800 --> 00:15:38,480
Speaker 3: To you again like the scuba people.

299
00:15:38,640 --> 00:15:41,600
Speaker 1: So the slewing unit is the it's where the mast

300
00:15:41,880 --> 00:15:44,880
Speaker 1: and the top functioning part of the crane meat and

301
00:15:44,920 --> 00:15:48,240
Speaker 1: it spins it around. It's what allows the whole thing

302
00:15:48,240 --> 00:15:49,160
Speaker 1: to spin around.

303
00:15:49,120 --> 00:15:49,400
Speaker 3: All right.

304
00:15:49,440 --> 00:15:50,920
Speaker 2: The next thing we have is that the you know,

305
00:15:50,960 --> 00:15:53,640
Speaker 2: the big long arm, that big working arm that extends

306
00:15:53,640 --> 00:15:55,720
Speaker 2: way out, the horizontal arm.

307
00:15:55,960 --> 00:16:00,080
Speaker 3: That lifts the stuff. Although it doesn't actually lift the stuff,

308
00:16:00,080 --> 00:16:00,880
Speaker 3: it holds the stuff.

309
00:16:01,280 --> 00:16:04,680
Speaker 2: That's called the jib arm. A jib is it's not

310
00:16:05,160 --> 00:16:08,040
Speaker 2: specific to cranes or all kinds of jib arms. If

311
00:16:08,080 --> 00:16:10,040
Speaker 2: you've ever worked on a movie set and they you know,

312
00:16:10,560 --> 00:16:13,160
Speaker 2: have crane shots and stuff like that. Those are called

313
00:16:13,240 --> 00:16:15,880
Speaker 2: jibs as well.

314
00:16:15,880 --> 00:16:18,080
Speaker 3: Why is it funny? Why are you laughing at everything.

315
00:16:18,000 --> 00:16:21,520
Speaker 1: Because you're drunk? No, I'm not drunk. I'm drunk ish,

316
00:16:21,720 --> 00:16:24,440
Speaker 1: but not fully, not enough to explain my last finess.

317
00:16:25,960 --> 00:16:28,800
Speaker 2: So the jib can go out, you know, a few

318
00:16:28,880 --> 00:16:33,280
Speaker 2: hundred feet sometimes for the extra large ones, and it

319
00:16:33,560 --> 00:16:37,880
Speaker 2: basically allows it to lift things up, swing it over,

320
00:16:38,080 --> 00:16:42,520
Speaker 2: and drop it off somewhere else. And if you're thinking, well,

321
00:16:42,880 --> 00:16:45,520
Speaker 2: that sounds a lot more complicated than that, it is,

322
00:16:45,520 --> 00:16:47,520
Speaker 2: and it isn't. It's not in that that's what that

323
00:16:47,640 --> 00:16:50,480
Speaker 2: jib arm is there for. But there is a something

324
00:16:50,520 --> 00:16:53,320
Speaker 2: called a load chart that you know, you really got

325
00:16:53,320 --> 00:16:56,360
Speaker 2: to be well acquainted with, because if you're picking up

326
00:16:56,400 --> 00:16:58,840
Speaker 2: something from the very tippy end of that three hundred

327
00:16:58,840 --> 00:17:01,360
Speaker 2: foot jib, not gonna be able to lift as much

328
00:17:01,440 --> 00:17:03,720
Speaker 2: as you would if that thing were pulled back to

329
00:17:03,840 --> 00:17:06,760
Speaker 2: like fifty or sixty feet because of physics, it would

330
00:17:06,760 --> 00:17:07,160
Speaker 2: tip over.

331
00:17:07,359 --> 00:17:11,800
Speaker 1: Yeah, you can't lift the full load of Volvo mid

332
00:17:11,840 --> 00:17:15,199
Speaker 1: sized SUVs that you could if it's much closer, if

333
00:17:15,240 --> 00:17:18,280
Speaker 1: the load's closer to the center of gravity for the

334
00:17:18,320 --> 00:17:19,280
Speaker 1: whole crane, right.

335
00:17:20,040 --> 00:17:24,080
Speaker 2: Yeah, So I guess that maximum lift capacity would be

336
00:17:24,240 --> 00:17:29,120
Speaker 2: when it's at its peak of you know position, yeah,

337
00:17:29,119 --> 00:17:31,280
Speaker 2: peak balance, like lifting, yeah, peak balance.

338
00:17:31,359 --> 00:17:35,240
Speaker 1: Right, So it would not necessarily be I don't know.

339
00:17:35,320 --> 00:17:37,400
Speaker 1: It depends on the weight of the load where that

340
00:17:37,560 --> 00:17:42,480
Speaker 1: peak of balance would be, right. So, but for the

341
00:17:42,560 --> 00:17:45,240
Speaker 1: heaviest for its maximum lift, it would probably be pretty

342
00:17:45,280 --> 00:17:50,000
Speaker 1: much close to the center of the jib arm. Maybe, yeah, No,

343
00:17:50,080 --> 00:17:54,080
Speaker 1: I think it's actually a little closer regardless. The thing

344
00:17:54,119 --> 00:17:56,879
Speaker 1: that I think is ingenious about all this is that

345
00:17:56,920 --> 00:18:00,800
Speaker 1: the jib arm never moves. It's static. It might move

346
00:18:00,880 --> 00:18:04,800
Speaker 1: like swiveling, but it's not swiveling itself. It's just swiveling

347
00:18:04,800 --> 00:18:08,359
Speaker 1: with the rest of the whole working part of the crane, right,

348
00:18:08,400 --> 00:18:12,160
Speaker 1: So the jib arm stays where it is. So they've

349
00:18:12,200 --> 00:18:15,320
Speaker 1: actually designed everything else around the fact that the jib

350
00:18:15,400 --> 00:18:19,879
Speaker 1: arm stays straight, and that's what allows loads to like

351
00:18:19,960 --> 00:18:22,399
Speaker 1: move toward the cab, away from the cab, toward the

352
00:18:22,480 --> 00:18:24,480
Speaker 1: end of the arm, toward the inside of the arm.

353
00:18:24,560 --> 00:18:28,840
Speaker 1: The jib arm through a bunch of pulleys and specifically

354
00:18:28,960 --> 00:18:32,399
Speaker 1: a something called the trolley which is attached to the

355
00:18:32,480 --> 00:18:35,160
Speaker 1: underside of the jib arm, and it's just what moves

356
00:18:35,200 --> 00:18:38,359
Speaker 1: back and forth along the jib arm, allowing you to

357
00:18:38,480 --> 00:18:41,520
Speaker 1: kind of move a load, you know, closer or further away,

358
00:18:41,560 --> 00:18:43,520
Speaker 1: depending on where the people on the ground need it.

359
00:18:44,440 --> 00:18:44,840
Speaker 3: Yeah.

360
00:18:44,920 --> 00:18:47,640
Speaker 2: Like if you stood up and put one arm out,

361
00:18:48,280 --> 00:18:51,479
Speaker 2: that arm would just stay there. And there's and picture

362
00:18:51,600 --> 00:18:54,760
Speaker 2: a little little carriage on the underside of your arm

363
00:18:55,119 --> 00:18:57,360
Speaker 2: that slides, you know, down to your fingertips and back

364
00:18:57,359 --> 00:18:57,919
Speaker 2: to your arm pit.

365
00:18:58,000 --> 00:19:00,960
Speaker 1: Yeah, that stuff that hangs down from your bicep. When

366
00:19:01,000 --> 00:19:03,720
Speaker 1: you just let your arms stay there, imagine that moving

367
00:19:03,720 --> 00:19:04,640
Speaker 1: towards your fingers.

368
00:19:05,160 --> 00:19:09,800
Speaker 2: Oh god, it's called aging. So your arms stays straight

369
00:19:09,800 --> 00:19:11,640
Speaker 2: the whole time, and that little carriage on the underside

370
00:19:11,640 --> 00:19:12,879
Speaker 2: of your arm is what's moving stuff.

371
00:19:12,920 --> 00:19:14,320
Speaker 3: And then if you want to move.

372
00:19:14,200 --> 00:19:16,800
Speaker 2: It from here to there, you turn your whole body

373
00:19:16,840 --> 00:19:19,040
Speaker 2: and you go er while you do it.

374
00:19:19,119 --> 00:19:19,320
Speaker 1: Yep.

375
00:19:19,560 --> 00:19:21,879
Speaker 2: So you know your kids will laugh and stuff, but

376
00:19:21,960 --> 00:19:24,120
Speaker 2: that's essentially it. That arms just stays there.

377
00:19:24,200 --> 00:19:26,560
Speaker 1: Yeah, and when you turn your whole body, your hips are.

378
00:19:26,400 --> 00:19:30,040
Speaker 3: Slewing, right, I guess so like Elvis.

379
00:19:30,520 --> 00:19:34,080
Speaker 1: So then the hook, the thing that actually hooks onto

380
00:19:34,080 --> 00:19:37,760
Speaker 1: the load that's just connected to the trolley. Right, it's

381
00:19:37,800 --> 00:19:40,920
Speaker 1: pretty neat because you actually raise and lower the hook.

382
00:19:41,560 --> 00:19:44,520
Speaker 1: So it's connected to a system of pulleys, like a

383
00:19:44,520 --> 00:19:48,440
Speaker 1: whole bunch of different pulleys. And when you connect these

384
00:19:48,440 --> 00:19:51,399
Speaker 1: pulleys together, it's called reaving. And so there's a certain

385
00:19:51,440 --> 00:19:54,879
Speaker 1: way to connect all these pulleys to maximize the just

386
00:19:54,920 --> 00:19:57,959
Speaker 1: the grip and traction they have while also allowing like

387
00:19:58,000 --> 00:20:02,280
Speaker 1: the heaviest possible load to kind of hang from that

388
00:20:02,400 --> 00:20:03,680
Speaker 1: cable without snapping.

389
00:20:04,480 --> 00:20:07,359
Speaker 2: Yeah, and it just works as a like a Roden reel,

390
00:20:07,359 --> 00:20:10,199
Speaker 2: like when you're fishing. You just wind it in to

391
00:20:10,280 --> 00:20:12,520
Speaker 2: raise it and let it out to lower it.

392
00:20:12,680 --> 00:20:16,800
Speaker 1: Now, that technically is found in the hoist unit, which

393
00:20:16,880 --> 00:20:20,119
Speaker 1: to me is just I mean, it's the thing that

394
00:20:20,160 --> 00:20:24,520
Speaker 1: makes everything move. Well, no, I guess this slewing unit

395
00:20:24,560 --> 00:20:27,560
Speaker 1: makes the thing moved to Anything that has to do

396
00:20:27,640 --> 00:20:30,200
Speaker 1: with the load, the hook, all of that stuff, it's

397
00:20:30,320 --> 00:20:31,760
Speaker 1: found in the hoist unit.

398
00:20:32,880 --> 00:20:36,480
Speaker 2: Yeah, and that works with that hook block through a

399
00:20:36,520 --> 00:20:41,200
Speaker 2: series of a series of pulleys. They're not just like, hey,

400
00:20:41,280 --> 00:20:44,479
Speaker 2: let's put get this gigantic pulley and a giant cable.

401
00:20:44,520 --> 00:20:47,560
Speaker 3: They want it. They want that cable running through several several.

402
00:20:47,280 --> 00:20:50,600
Speaker 1: Pulleys right, and so that goes up and then usually

403
00:20:50,720 --> 00:20:53,360
Speaker 1: up above the top of the jib arm and then

404
00:20:53,400 --> 00:20:57,000
Speaker 1: back behind to the counter jib where it sits. I

405
00:20:57,000 --> 00:21:00,359
Speaker 1: think usually the hoist unit sits behind the counter waits.

406
00:21:00,880 --> 00:21:03,440
Speaker 1: And it consists of a big, old, burly one hundred

407
00:21:03,440 --> 00:21:08,679
Speaker 1: and eighty horsepower motor that's spinning, a giant drum that

408
00:21:08,720 --> 00:21:11,520
Speaker 1: has a bunch of steel cable wound around it. So

409
00:21:11,560 --> 00:21:14,760
Speaker 1: the whole thing acts like a fishing line. A rodden

410
00:21:14,840 --> 00:21:19,080
Speaker 1: reel essentially, is the best analogy for it. When you

411
00:21:19,119 --> 00:21:21,840
Speaker 1: want to lower something, the drum spins and the line

412
00:21:21,840 --> 00:21:23,880
Speaker 1: pays out. When you want to raise it back up,

413
00:21:24,040 --> 00:21:26,480
Speaker 1: the drum spins the other way and reels the line

414
00:21:26,520 --> 00:21:30,320
Speaker 1: in in mister, you got a big old couple hundred

415
00:21:30,400 --> 00:21:33,760
Speaker 1: ton fish on the end of your line. Their congratulations.

416
00:21:34,560 --> 00:21:34,840
Speaker 3: Yeah.

417
00:21:34,880 --> 00:21:37,720
Speaker 2: And that cable is I mean, you would think like

418
00:21:37,800 --> 00:21:40,080
Speaker 2: it's got to be like three feet around or something,

419
00:21:40,080 --> 00:21:43,560
Speaker 2: but cable is really really strong. I'm not sure how

420
00:21:43,600 --> 00:21:46,560
Speaker 2: big this cable is, but I've seen cables that like

421
00:21:46,640 --> 00:21:49,640
Speaker 2: pull a boat out of the water, and those things

422
00:21:49,640 --> 00:21:53,720
Speaker 2: are not big around at all. And I'm constantly thinking, well,

423
00:21:53,960 --> 00:21:57,440
Speaker 2: I wonder when I'm going to see somebody's boat snap off. Yeah,

424
00:21:57,480 --> 00:22:00,000
Speaker 2: and it just doesn't happen. Cable is just super super strong.

425
00:22:00,119 --> 00:22:00,919
Speaker 1: Yeah, for sure.

426
00:22:01,240 --> 00:22:03,679
Speaker 2: You know, next time we do a topic like this,

427
00:22:03,840 --> 00:22:05,679
Speaker 2: we should get two five year olds to come in

428
00:22:05,760 --> 00:22:09,640
Speaker 2: and explain this part because they would do it such

429
00:22:09,680 --> 00:22:10,439
Speaker 2: so much more simple.

430
00:22:10,480 --> 00:22:10,919
Speaker 1: Do you think so?

431
00:22:11,840 --> 00:22:14,520
Speaker 3: I think so simply. Yeah, all right, two five or

432
00:22:14,520 --> 00:22:15,800
Speaker 3: maybe maybe four year olds.

433
00:22:17,280 --> 00:22:20,080
Speaker 2: Okay, it's got a counter jib, but that is if

434
00:22:20,080 --> 00:22:21,679
Speaker 2: you look at the tower crane and you see that

435
00:22:21,720 --> 00:22:24,000
Speaker 2: big long arm on the other side of the mast,

436
00:22:24,040 --> 00:22:27,080
Speaker 2: you're going to see a much shorter horizontal arm out

437
00:22:27,080 --> 00:22:28,399
Speaker 2: of what I guess you would call the back of

438
00:22:28,440 --> 00:22:31,159
Speaker 2: the crane, and that is going to hold the counterweights

439
00:22:31,160 --> 00:22:34,960
Speaker 2: because you got to counterbalance all those bobo suvsh with

440
00:22:35,040 --> 00:22:37,560
Speaker 2: a lot of serious weights. And that is that those

441
00:22:37,560 --> 00:22:43,120
Speaker 2: are the counterweights. The K ten thousand requires almost as

442
00:22:43,119 --> 00:22:47,320
Speaker 2: many counterweights as it requires for like the maximum lift.

443
00:22:47,359 --> 00:22:50,520
Speaker 2: It's four hundred and ninety one thousand and change of

444
00:22:50,640 --> 00:22:53,680
Speaker 2: poundage compared to what I say, like five eighty or

445
00:22:53,720 --> 00:22:54,320
Speaker 2: something like that.

446
00:22:55,040 --> 00:22:59,160
Speaker 1: Yeah, it's a yeah. And there's just these huge concrete

447
00:22:59,160 --> 00:23:02,280
Speaker 1: slabs that are shaped slightly like a t so the

448
00:23:02,320 --> 00:23:04,800
Speaker 1: bottom parts fit into a slot, but the tops won't,

449
00:23:04,840 --> 00:23:08,359
Speaker 1: so they just dangle there. It's nuts. Actually, if you

450
00:23:08,400 --> 00:23:11,640
Speaker 1: think about what's going on hundreds of feet up in the.

451
00:23:11,600 --> 00:23:16,520
Speaker 2: Air, well, what's nuts is when they're not lifting anything,

452
00:23:17,000 --> 00:23:20,159
Speaker 2: those counterweights make the crane kind of tip backward a

453
00:23:20,200 --> 00:23:23,719
Speaker 2: little bit. And if you're a crane operator and you

454
00:23:23,760 --> 00:23:26,560
Speaker 2: start lifting and dropping things off, that crane does a

455
00:23:26,560 --> 00:23:30,000
Speaker 2: little weeble wobble of a few feet when it's lifting

456
00:23:30,040 --> 00:23:32,560
Speaker 2: and releasing things, and you just gotta you know, you

457
00:23:32,640 --> 00:23:34,040
Speaker 2: gotta be used to that, I guess.

458
00:23:34,160 --> 00:23:36,280
Speaker 1: Yeah, yeah, I'm sure that takes a lot of getting

459
00:23:36,359 --> 00:23:36,639
Speaker 1: used to.

460
00:23:37,440 --> 00:23:37,800
Speaker 3: Yeah.

461
00:23:37,840 --> 00:23:40,639
Speaker 1: And then there's a tower peak, which hammerhead tower cranes

462
00:23:40,680 --> 00:23:43,280
Speaker 1: don't usually have a peak, it's just flat all the

463
00:23:43,320 --> 00:23:46,320
Speaker 1: way across. But sometimes they have a nice little almost

464
00:23:46,320 --> 00:23:49,560
Speaker 1: like a sailboat sail masting kind of thing. Yeah, And

465
00:23:49,680 --> 00:23:55,159
Speaker 1: usually that's to help support from above the jib because

466
00:23:55,200 --> 00:23:57,760
Speaker 1: those things extend out pretty far and they're cann of levered,

467
00:23:57,880 --> 00:24:00,359
Speaker 1: so they can use all the support they can get.

468
00:24:00,760 --> 00:24:05,360
Speaker 2: There's more cableage basically right kind of supporting it from above, yes, yeah, yeah,

469
00:24:05,560 --> 00:24:08,480
Speaker 2: And there's one more big, big piece of equipment as

470
00:24:08,480 --> 00:24:10,800
Speaker 2: far as importance goes, if you asked me, it could

471
00:24:10,800 --> 00:24:12,320
Speaker 2: be a little bigger. I have some thoughts on how

472
00:24:12,320 --> 00:24:15,600
Speaker 2: to improve these things. But that is the operator cab

473
00:24:16,000 --> 00:24:19,560
Speaker 2: where the person sits the crane operator sits for eight

474
00:24:19,600 --> 00:24:21,840
Speaker 2: to twelve to fifteen hours a day, depending on how

475
00:24:21,920 --> 00:24:23,240
Speaker 2: much they're being put to work.

476
00:24:23,359 --> 00:24:27,800
Speaker 1: Yeah, and it's like roughly smallish walk in closet size

477
00:24:28,880 --> 00:24:33,000
Speaker 1: in a mid market priced suburban home.

478
00:24:34,480 --> 00:24:37,399
Speaker 2: So here are my two thoughts. A. These people climb

479
00:24:37,520 --> 00:24:38,960
Speaker 2: up a ladder to get there.

480
00:24:39,800 --> 00:24:41,360
Speaker 1: Yeah, how long does it take them? Chuck?

481
00:24:42,240 --> 00:24:44,399
Speaker 2: It can take like ten minutes or more, depending on

482
00:24:44,480 --> 00:24:47,560
Speaker 2: how fast they're climbing. So my first improvement is you

483
00:24:47,680 --> 00:24:50,200
Speaker 2: got to get them out of like off that ladder.

484
00:24:50,280 --> 00:24:52,240
Speaker 2: No one needs to be climbing up that thing at

485
00:24:52,240 --> 00:24:54,080
Speaker 2: the beginning or the end of a shift.

486
00:24:54,240 --> 00:24:55,280
Speaker 1: Okay, check one.

487
00:24:56,040 --> 00:24:58,560
Speaker 2: There's got to be a way to get somebody up there,

488
00:24:59,119 --> 00:25:02,520
Speaker 2: like a rig they attached them to and mechanically pulley

489
00:25:02,600 --> 00:25:05,919
Speaker 2: themselves up or something like that. Okay, So that's my

490
00:25:05,960 --> 00:25:08,560
Speaker 2: first suggestion. The other one is that thing needs a

491
00:25:08,560 --> 00:25:12,680
Speaker 2: little tiny toilet. There's no bathroom. There's climate controlled, which

492
00:25:12,720 --> 00:25:16,560
Speaker 2: is great, but they don't have a toilet, and Dave

493
00:25:16,640 --> 00:25:19,200
Speaker 2: said he found out they pee in a bottle and

494
00:25:19,280 --> 00:25:22,720
Speaker 2: poop in a plastic bag. Like get a little bitty

495
00:25:22,760 --> 00:25:25,040
Speaker 2: You could make that thing a little bit bigger and

496
00:25:25,240 --> 00:25:28,439
Speaker 2: put a couple of mod cons in there for these people.

497
00:25:28,600 --> 00:25:31,840
Speaker 1: Yeah, no, it's true for sure. I think the thing

498
00:25:31,880 --> 00:25:35,080
Speaker 1: that fascinated me the most about the cab, besides not

499
00:25:35,160 --> 00:25:41,080
Speaker 1: having a bathroom, is that the windshield essentially extends all

500
00:25:41,119 --> 00:25:44,840
Speaker 1: the way down below the operator's feet, so when you're

501
00:25:44,880 --> 00:25:48,320
Speaker 1: sitting in the seat, your feet are dangling over the

502
00:25:48,400 --> 00:25:53,080
Speaker 1: ground and hundreds and hundreds of feet below. Yeah, it's

503
00:25:53,119 --> 00:25:53,600
Speaker 1: really something.

504
00:25:53,680 --> 00:25:54,200
Speaker 3: List see.

505
00:25:54,880 --> 00:25:56,880
Speaker 2: I'm not trying to be gross, but this is real

506
00:25:56,960 --> 00:26:00,000
Speaker 2: world stuff. What if you've got you know, diarrhea or something,

507
00:26:00,080 --> 00:26:00,880
Speaker 2: then then you're up there.

508
00:26:00,960 --> 00:26:02,359
Speaker 1: Well, you know, I saw I saw a lot of

509
00:26:02,520 --> 00:26:03,400
Speaker 1: real pro for sure.

510
00:26:03,440 --> 00:26:03,719
Speaker 3: It is.

511
00:26:03,920 --> 00:26:07,960
Speaker 1: I saw a lot of like blogs and articles about

512
00:26:08,000 --> 00:26:10,240
Speaker 1: how as a crane operator you really need to take

513
00:26:10,280 --> 00:26:13,320
Speaker 1: care of yourself, like probably more than the average construction

514
00:26:13,640 --> 00:26:16,520
Speaker 1: worker would. In addition to like getting sleep so you're

515
00:26:16,520 --> 00:26:19,800
Speaker 1: not like off your game on any day. You want

516
00:26:19,800 --> 00:26:22,879
Speaker 1: to eat well, at least for that reason, Like you

517
00:26:22,880 --> 00:26:26,359
Speaker 1: don't want to eat like a dozen wings for breakfast, lunch,

518
00:26:26,359 --> 00:26:29,760
Speaker 1: and dinner. That's a bad Idelly, no chili, nothing like

519
00:26:29,760 --> 00:26:34,840
Speaker 1: that chili dog's chili concarne, none of that stuff. Yeah,

520
00:26:34,880 --> 00:26:39,119
Speaker 1: this is a real consideration for sure. And because it

521
00:26:39,200 --> 00:26:42,080
Speaker 1: takes at least ten minutes to get to the ground,

522
00:26:43,600 --> 00:26:45,320
Speaker 1: of course, you're not going to stop every time you

523
00:26:45,320 --> 00:26:47,600
Speaker 1: have to go to the potty. You're gonna just go

524
00:26:47,720 --> 00:26:48,120
Speaker 1: up there.

525
00:26:48,720 --> 00:26:50,439
Speaker 3: Yeah, you put a little tiny body up there, it's

526
00:26:50,440 --> 00:26:50,920
Speaker 3: all I'm saying.

527
00:26:50,920 --> 00:26:53,639
Speaker 1: Plus, also, even if you don't, even if you're like,

528
00:26:53,720 --> 00:26:56,200
Speaker 1: I want to climb back down and this is going

529
00:26:56,240 --> 00:26:57,879
Speaker 1: to be awful, So I need to get out of

530
00:26:57,880 --> 00:27:02,119
Speaker 1: this cap. When you're climbing down and you go to

531
00:27:02,160 --> 00:27:04,120
Speaker 1: the bathroom and then you have to climb back up,

532
00:27:04,640 --> 00:27:07,720
Speaker 1: that could be forty five minutes an hour worth of time.

533
00:27:07,800 --> 00:27:08,399
Speaker 3: That's my point.

534
00:27:08,440 --> 00:27:12,560
Speaker 1: That the entire construction site has just essentially shut down

535
00:27:12,600 --> 00:27:15,159
Speaker 1: waiting on you, or whatever was coming next is just

536
00:27:15,200 --> 00:27:18,520
Speaker 1: waiting on you. You have literally slowed down the entire project.

537
00:27:18,880 --> 00:27:21,639
Speaker 1: That's the amount of pressure that's on the crane operator

538
00:27:21,800 --> 00:27:22,560
Speaker 1: at all times.

539
00:27:22,600 --> 00:27:25,879
Speaker 3: Typically, little bathroom solve that whole problem.

540
00:27:25,960 --> 00:27:28,960
Speaker 1: Yeah, at the very least one of those like stadium

541
00:27:29,040 --> 00:27:31,200
Speaker 1: catheters that people use at football games.

542
00:27:32,880 --> 00:27:35,359
Speaker 2: Should we take a break, Yes, all right, we'll be

543
00:27:35,440 --> 00:28:03,720
Speaker 2: right back with more on tower cranes.

544
00:28:05,040 --> 00:28:07,680
Speaker 1: Okay, Chuck, So now we're at probably the coolest part.

545
00:28:07,720 --> 00:28:11,440
Speaker 1: You thought everything was cool thus far, just wait for this,

546
00:28:12,000 --> 00:28:15,879
Speaker 1: because you mentioned the Favel Brothers out of Australia and

547
00:28:16,320 --> 00:28:19,320
Speaker 1: they invented that kangaroo crane, which from what I can tell,

548
00:28:19,359 --> 00:28:22,120
Speaker 1: no one calls it that anymore. They probably did at first.

549
00:28:22,119 --> 00:28:25,240
Speaker 1: Now they call them climbing cranes. There's actually two ways

550
00:28:25,280 --> 00:28:30,320
Speaker 1: they figured out to make cranes climb to essentially build themselves.

551
00:28:30,640 --> 00:28:34,000
Speaker 1: That's what they do because there's only so much of

552
00:28:34,040 --> 00:28:38,959
Speaker 1: the mast that you can build using smaller cranes. Eventually,

553
00:28:39,200 --> 00:28:41,880
Speaker 1: the crane's going to get too tall for the cranes

554
00:28:41,920 --> 00:28:45,360
Speaker 1: that are helping build it to lift, and it needs

555
00:28:45,400 --> 00:28:47,280
Speaker 1: to start taking over. It needs to stand on its

556
00:28:47,320 --> 00:28:50,880
Speaker 1: own two feet and take charge of its own life.

557
00:28:51,080 --> 00:28:52,520
Speaker 3: Yeah, or really four legs.

558
00:28:52,600 --> 00:28:52,880
Speaker 1: Sure.

559
00:28:54,600 --> 00:28:57,560
Speaker 2: The two methods are top climbing and bottom climbing. So

560
00:28:57,720 --> 00:29:00,280
Speaker 2: at the beginning of each job, or when you're going

561
00:29:00,280 --> 00:29:01,800
Speaker 2: to get a job, I guess you have to determine

562
00:29:01,840 --> 00:29:05,320
Speaker 2: if you're a top or a bottom, and for top climbing,

563
00:29:06,560 --> 00:29:08,920
Speaker 2: it really helps. I got to say to look at

564
00:29:08,960 --> 00:29:12,880
Speaker 2: a video like Dave sent us these video demos. We're

565
00:29:12,920 --> 00:29:15,600
Speaker 2: going to do our best to describe this stuff. If

566
00:29:15,600 --> 00:29:17,240
Speaker 2: you happen to be at home or a safe place

567
00:29:17,280 --> 00:29:20,000
Speaker 2: when you're not driving your car, you know, give yourself

568
00:29:20,040 --> 00:29:21,120
Speaker 2: thirty seconds and check it out.

569
00:29:21,280 --> 00:29:24,160
Speaker 1: I found a good one for top climbing search Stafford

570
00:29:24,280 --> 00:29:30,479
Speaker 1: Soima soo Ima, okay. And then for bottom climbing, Hans

571
00:29:30,520 --> 00:29:35,120
Speaker 1: Leber's company has a great video on it too.

572
00:29:35,240 --> 00:29:35,920
Speaker 3: I love these guys.

573
00:29:35,960 --> 00:29:37,920
Speaker 2: Hopefully this is going to blow up Andy and be like, man,

574
00:29:37,920 --> 00:29:39,280
Speaker 2: where are we getting all these views from.

575
00:29:39,320 --> 00:29:41,760
Speaker 1: We've gotten one hundred views in the last six months.

576
00:29:41,800 --> 00:29:45,400
Speaker 2: Now, yeah, I hope that doesn't mean like we should

577
00:29:45,480 --> 00:29:48,959
Speaker 2: invest in buying more cranes because of all the interest.

578
00:29:49,040 --> 00:29:51,520
Speaker 1: Hey, that's on them if they miousread the market that badly.

579
00:29:52,640 --> 00:29:56,480
Speaker 2: All right, So the climbing frame is what is necessary

580
00:29:56,480 --> 00:30:00,600
Speaker 2: to build a top climbing crane. The climb frame is

581
00:30:00,640 --> 00:30:03,440
Speaker 2: three sided. It's got you know, three sides and then

582
00:30:03,440 --> 00:30:06,000
Speaker 2: one open side, and it's built around the base of

583
00:30:06,040 --> 00:30:08,320
Speaker 2: the mast kind of like Dave describe it as like

584
00:30:08,360 --> 00:30:11,160
Speaker 2: a cage that's a little wider than the mass, so

585
00:30:11,200 --> 00:30:13,360
Speaker 2: it can slide up and down on the outside, which

586
00:30:13,400 --> 00:30:14,240
Speaker 2: makes a lot of sense.

587
00:30:14,320 --> 00:30:17,400
Speaker 1: You know those construction elevators that they have on construction

588
00:30:17,520 --> 00:30:20,120
Speaker 1: sites that are essentially that that people like used to

589
00:30:20,160 --> 00:30:23,160
Speaker 1: get up. Imagine that. But there's no place for you

590
00:30:23,280 --> 00:30:26,920
Speaker 1: to stand because it's the mast of the crane is

591
00:30:26,960 --> 00:30:30,400
Speaker 1: going through it. Yeah, that's a much more convoluted way

592
00:30:30,440 --> 00:30:31,000
Speaker 1: to think of it.

593
00:30:31,040 --> 00:30:33,080
Speaker 3: I like to think, yeah, exactly.

594
00:30:34,040 --> 00:30:36,160
Speaker 2: The cool thing about this climbing frame is it is

595
00:30:36,240 --> 00:30:39,240
Speaker 2: equipped with these hydraulic jacks. So what it does is

596
00:30:40,080 --> 00:30:42,680
Speaker 2: it they have all these you know, trusses in a

597
00:30:43,080 --> 00:30:46,280
Speaker 2: very straight line, because while you're doing this, that jib

598
00:30:46,400 --> 00:30:50,960
Speaker 2: arm has to stay completely straight and still or I'm sorry, yeah,

599
00:30:50,960 --> 00:30:53,160
Speaker 2: that long arm. You don't want it moving around, and

600
00:30:53,200 --> 00:30:54,880
Speaker 2: you'll see why in a second. So they line them

601
00:30:54,880 --> 00:30:58,680
Speaker 2: all up in a row, and that climbing frame goes

602
00:30:58,880 --> 00:31:03,280
Speaker 2: down and it picks up one of these trusses, or

603
00:31:03,320 --> 00:31:05,160
Speaker 2: you know, it doesn't pick it up. I imagine it

604
00:31:05,160 --> 00:31:08,880
Speaker 2: gets loaded in or whatever, and then these hydraulic jacks

605
00:31:08,960 --> 00:31:12,120
Speaker 2: push it up, you know, kind of you know, a

606
00:31:12,160 --> 00:31:15,480
Speaker 2: few feet at a time. Basically it's you know, decompressing

607
00:31:15,560 --> 00:31:18,800
Speaker 2: and compressing and inching this thing up and up and

608
00:31:18,880 --> 00:31:21,360
Speaker 2: up until it gets to the top of where you

609
00:31:21,440 --> 00:31:25,560
Speaker 2: need a new section, and then they slide it in

610
00:31:25,760 --> 00:31:28,600
Speaker 2: and attach it. But the frightening part is all of

611
00:31:28,600 --> 00:31:32,480
Speaker 2: this is done like this thing has to be unbolted

612
00:31:33,000 --> 00:31:35,560
Speaker 2: another to bolt in order to bolt the new section on.

613
00:31:35,800 --> 00:31:38,960
Speaker 2: So there's a very tenuous time where everything has just

614
00:31:39,040 --> 00:31:41,520
Speaker 2: got to be perfectly imbalanced while they unbolt this thing.

615
00:31:41,600 --> 00:31:44,360
Speaker 1: Yeah, and what's scary is at that most tenuous time,

616
00:31:44,760 --> 00:31:47,880
Speaker 1: that's when the crane is lifting the next mass section

617
00:31:48,200 --> 00:31:50,920
Speaker 1: up so that it can be slid into that open

618
00:31:52,000 --> 00:31:54,240
Speaker 1: fourth wall of the climbing frame.

619
00:31:54,960 --> 00:31:58,360
Speaker 2: It's yeah, really, and the drivers, the operators even out

620
00:31:58,400 --> 00:32:00,400
Speaker 2: because they don't even want anyone in the cab moving

621
00:32:00,440 --> 00:32:02,200
Speaker 2: around like you know, with diarrhea.

622
00:32:03,120 --> 00:32:06,520
Speaker 1: Right. But no, I saw in one video that the

623
00:32:06,520 --> 00:32:09,080
Speaker 1: the crane had to have the operator in there to

624
00:32:09,680 --> 00:32:11,880
Speaker 1: lift up the east each mass section.

625
00:32:12,720 --> 00:32:14,320
Speaker 2: Well, I saw that a lot of times they're not

626
00:32:14,360 --> 00:32:16,959
Speaker 2: in there. So some may be self operational and some

627
00:32:17,040 --> 00:32:20,760
Speaker 2: may require just a very steady h you know, someone

628
00:32:20,840 --> 00:32:22,080
Speaker 2: on some emodium maintaince.

629
00:32:22,080 --> 00:32:23,960
Speaker 1: I mean, yeah, no, that makes sense that there wouldn't

630
00:32:23,960 --> 00:32:26,120
Speaker 1: be any in there because it's it's very dangerous because

631
00:32:26,160 --> 00:32:29,360
Speaker 1: the only thing connecting the entire top part of the crane,

632
00:32:29,400 --> 00:32:31,840
Speaker 1: which is already built to the bottom of the mast,

633
00:32:32,000 --> 00:32:34,520
Speaker 1: is that climbing frame at those points when they're starting

634
00:32:34,600 --> 00:32:37,239
Speaker 1: to move a new section in. But when you do this,

635
00:32:37,800 --> 00:32:39,880
Speaker 1: you can do this up till what was it about,

636
00:32:39,960 --> 00:32:44,800
Speaker 1: you know, four hundred feet where the whole thing tops out, Like, yeah,

637
00:32:44,960 --> 00:32:47,920
Speaker 1: that's I can't imagine seeing something like that, let alone

638
00:32:47,960 --> 00:32:49,680
Speaker 1: working on it, because I don't know if you said

639
00:32:50,280 --> 00:32:55,640
Speaker 1: on that climbing frame, there's some dudes being gender neutral

640
00:32:55,680 --> 00:32:59,239
Speaker 1: here riding that thing, like you're a dude if you

641
00:32:59,280 --> 00:33:03,880
Speaker 1: are still making giant pins into the mass frame sections

642
00:33:04,280 --> 00:33:09,400
Speaker 1: to erect a giant, a giant tower crane. That's just

643
00:33:09,640 --> 00:33:11,680
Speaker 1: the kind of personality it takes, I think.

644
00:33:12,520 --> 00:33:17,160
Speaker 2: Yeah, And I had always assumed these were telescoping like

645
00:33:17,240 --> 00:33:19,400
Speaker 2: a fire truck ladder.

646
00:33:19,440 --> 00:33:19,720
Speaker 3: Nope.

647
00:33:20,280 --> 00:33:22,240
Speaker 2: I thought it was just some huge unit on the

648
00:33:22,240 --> 00:33:24,640
Speaker 2: ground that could just telescope up to four hundred feet.

649
00:33:25,120 --> 00:33:27,200
Speaker 2: The fact that this is how it's done is remarkable.

650
00:33:27,280 --> 00:33:29,840
Speaker 1: Yeah, So you can almost imagine the climbing frame is

651
00:33:29,880 --> 00:33:34,080
Speaker 1: like a giant speculum that separates the top of the

652
00:33:35,280 --> 00:33:38,160
Speaker 1: tower crane from the bottom, and you insert another section

653
00:33:38,200 --> 00:33:39,240
Speaker 1: and then it does it again.

654
00:33:40,520 --> 00:33:43,840
Speaker 2: All right, you explained the bottom because I got it

655
00:33:43,880 --> 00:33:46,400
Speaker 2: and I saw the video, but I had a couple

656
00:33:46,400 --> 00:33:47,000
Speaker 2: of questions.

657
00:33:47,320 --> 00:33:52,520
Speaker 1: Oh okay, all right, So bottom climbing you do the

658
00:33:52,640 --> 00:33:55,120
Speaker 1: opposite with the top climbing. You're adding the new sections

659
00:33:55,120 --> 00:33:58,760
Speaker 1: at the top. At the bottom. You build the crane

660
00:33:58,840 --> 00:34:02,760
Speaker 1: like any other tower cran to start up to two hundred,

661
00:34:02,800 --> 00:34:05,440
Speaker 1: three hundred feet whatever, and you use it like normal.

662
00:34:05,760 --> 00:34:08,839
Speaker 1: But the difference is with the bottom climbing crane, you

663
00:34:08,920 --> 00:34:11,960
Speaker 1: build the building around the crane.

664
00:34:12,200 --> 00:34:14,520
Speaker 3: With the top climbing inside the building exactly.

665
00:34:14,560 --> 00:34:16,960
Speaker 1: Top climbing is outside of the building. It stays outside

666
00:34:16,960 --> 00:34:19,120
Speaker 1: of the building the whole time. Bottom climbing, you build

667
00:34:19,400 --> 00:34:22,880
Speaker 1: the building around the crane, and eventually, as the building

668
00:34:22,920 --> 00:34:25,760
Speaker 1: gets tall enough, it starts to serve as the support

669
00:34:25,840 --> 00:34:30,200
Speaker 1: structure for the crane, because eventually you have to decouple

670
00:34:30,280 --> 00:34:33,960
Speaker 1: the crane from the foundation that was poured for it,

671
00:34:34,000 --> 00:34:39,279
Speaker 1: like any other crane, and there's a jack that climbs up.

672
00:34:39,320 --> 00:34:42,440
Speaker 1: These climbing rails essentially two ladders that are on the

673
00:34:42,480 --> 00:34:47,160
Speaker 1: outside of the crane. Itself, and it pushes the crane

674
00:34:47,280 --> 00:34:51,280
Speaker 1: up little by little, usually about three stories at a time.

675
00:34:51,920 --> 00:34:55,560
Speaker 1: And so now the crane has lost its bottom section

676
00:34:55,800 --> 00:34:58,000
Speaker 1: because the bottom section is now three stories above it,

677
00:34:58,640 --> 00:35:01,279
Speaker 1: and the top three stories is now unsecured to the

678
00:35:01,280 --> 00:35:03,799
Speaker 1: next top three stories of the building. So they then

679
00:35:03,960 --> 00:35:06,680
Speaker 1: secure that to the building with callers, and then they

680
00:35:06,719 --> 00:35:11,480
Speaker 1: disassemble everything below it and build the building out around

681
00:35:11,640 --> 00:35:14,000
Speaker 1: the shaft where the crane used to be. They fill

682
00:35:14,000 --> 00:35:16,560
Speaker 1: it in as the crane just moves higher and higher

683
00:35:16,600 --> 00:35:21,680
Speaker 1: and higher. And with this method you can build as

684
00:35:21,719 --> 00:35:24,920
Speaker 1: tall a building as physics will allow, because the crane

685
00:35:24,960 --> 00:35:28,520
Speaker 1: grows upward with the building as the building grows upward.

686
00:35:28,719 --> 00:35:30,880
Speaker 2: Yeah, it's amazing, and I guess i'd answer my question.

687
00:35:31,000 --> 00:35:34,040
Speaker 2: My question was sort of if you need that kind

688
00:35:34,040 --> 00:35:39,120
Speaker 2: of foundation for a freestanding outside, like is being attached

689
00:35:39,160 --> 00:35:40,759
Speaker 2: to the building enough And I guess it is.

690
00:35:42,080 --> 00:35:45,000
Speaker 1: Yeah, yeah, yes, for sure. And I think it's like

691
00:35:45,080 --> 00:35:46,880
Speaker 1: special parts of the building. It's not like they attach

692
00:35:46,920 --> 00:35:50,000
Speaker 1: it to like studs and drywall or something like that.

693
00:35:50,200 --> 00:35:53,399
Speaker 1: Like I think the building is designed to accommodate this pain.

694
00:35:54,040 --> 00:35:57,600
Speaker 3: Also, yeah, I think that more than answer my question.

695
00:35:58,080 --> 00:36:00,000
Speaker 1: Yes, but those are the two ways that you can

696
00:36:00,120 --> 00:36:03,319
Speaker 1: raise a crane, and they're both spectacular in their in

697
00:36:03,360 --> 00:36:04,560
Speaker 1: their ingeniousness.

698
00:36:04,800 --> 00:36:08,080
Speaker 2: All right, so that's how they're built. Bottom up or

699
00:36:08,160 --> 00:36:09,919
Speaker 2: top down, not top down.

700
00:36:10,200 --> 00:36:11,000
Speaker 3: How do we say.

701
00:36:12,920 --> 00:36:15,560
Speaker 1: Either one? I think bottom climbing or top climbing.

702
00:36:15,640 --> 00:36:16,640
Speaker 3: You mean, I guess.

703
00:36:16,719 --> 00:36:19,400
Speaker 2: So those are the giant tower cranes. We mentioned that

704
00:36:19,440 --> 00:36:24,400
Speaker 2: luffing crane at the beginning. This is a This is

705
00:36:24,440 --> 00:36:25,880
Speaker 2: when you don't have a ton of space, and I

706
00:36:25,880 --> 00:36:28,520
Speaker 2: saw a video where it showed, especially when there's multiple

707
00:36:28,560 --> 00:36:31,160
Speaker 2: cranes on a job swinging around. Yeah, you got to

708
00:36:31,160 --> 00:36:33,439
Speaker 2: think about the fact that, like if you're swinging something

709
00:36:33,440 --> 00:36:35,800
Speaker 2: three hundred feet, everything has got to be out of

710
00:36:35,840 --> 00:36:38,440
Speaker 2: the way of that swing as well. So when you

711
00:36:38,440 --> 00:36:41,520
Speaker 2: have tighter spaces, you might want a luffing jib arm.

712
00:36:41,640 --> 00:36:45,440
Speaker 2: And that is when the horizontal arm actually raises and lowers.

713
00:36:45,880 --> 00:36:50,000
Speaker 2: So instead of having that that block and hook going

714
00:36:50,120 --> 00:36:53,399
Speaker 2: you know, up and down on with a pulley, it's

715
00:36:53,520 --> 00:36:55,880
Speaker 2: just sort of there and the action of lifting that

716
00:36:56,040 --> 00:36:58,839
Speaker 2: arm up and down is what brings the the thing

717
00:36:58,920 --> 00:37:00,720
Speaker 2: on the hook closer further away.

718
00:37:01,400 --> 00:37:03,640
Speaker 1: Yeah, if you've ever seen like one of those wrecking

719
00:37:03,719 --> 00:37:07,520
Speaker 1: balls that they use that's attached to a luffing crane.

720
00:37:07,520 --> 00:37:11,600
Speaker 3: Typically, sure, what about self erectors?

721
00:37:12,480 --> 00:37:15,080
Speaker 1: These are pretty neat. They usually show up on the

722
00:37:15,120 --> 00:37:17,680
Speaker 1: back of like a truck, and the truck puts down

723
00:37:17,719 --> 00:37:21,040
Speaker 1: some feet for stabilization and probably lifts the truck off

724
00:37:21,080 --> 00:37:25,719
Speaker 1: of the ground and a crane just kind of pops out.

725
00:37:25,760 --> 00:37:29,239
Speaker 1: It folds out. Telescope, it's that telescoping effect that you

726
00:37:29,320 --> 00:37:34,360
Speaker 1: were You thought the original tower cranes were doing this essentially.

727
00:37:33,920 --> 00:37:34,960
Speaker 3: Does this is a folding.

728
00:37:35,200 --> 00:37:39,680
Speaker 1: It's not telescoping, okay, but it's it's folded up in itself.

729
00:37:39,719 --> 00:37:43,000
Speaker 1: It's all there and it unfurls. I guess is what

730
00:37:43,040 --> 00:37:43,879
Speaker 1: I'm after here.

731
00:37:43,960 --> 00:37:45,319
Speaker 3: Yeah, I just want to make sure you knew what

732
00:37:45,360 --> 00:37:46,480
Speaker 3: telescoping meant.

733
00:37:46,719 --> 00:37:50,319
Speaker 1: I learned what telescoping means and slewing thanks to you

734
00:37:50,440 --> 00:37:51,600
Speaker 1: in this one episode.

735
00:37:51,719 --> 00:37:52,120
Speaker 3: That's right.

736
00:37:52,160 --> 00:37:54,840
Speaker 2: These thing's just unfold into the sky and it's a

737
00:37:54,880 --> 00:37:57,080
Speaker 2: really also some really cool videos you can watch.

738
00:37:57,560 --> 00:37:59,480
Speaker 3: Yeah, should we take another break?

739
00:38:00,480 --> 00:38:02,720
Speaker 1: Well, before we do, I want to take another crackhet

740
00:38:02,719 --> 00:38:04,080
Speaker 1: explaining bottom climbing.

741
00:38:05,000 --> 00:38:33,600
Speaker 3: We'll be right back, all right.

742
00:38:33,640 --> 00:38:36,799
Speaker 2: We talked a little bit about the operator, but there

743
00:38:36,840 --> 00:38:39,520
Speaker 2: are all kinds of a team of people that work

744
00:38:39,600 --> 00:38:42,800
Speaker 2: with these cranes. Obviously, in the US there's a certifying

745
00:38:42,840 --> 00:38:47,680
Speaker 2: body called the n c c c O National Commission

746
00:38:47,719 --> 00:38:52,239
Speaker 2: for the Certification of Crane Operators, and so that's that's

747
00:38:52,280 --> 00:38:56,000
Speaker 2: the big job. That's the most experienced person. They have

748
00:38:56,120 --> 00:38:58,400
Speaker 2: worked on all these other jobs that we're about to

749
00:38:58,440 --> 00:39:00,360
Speaker 2: talk about for years and years before they get to

750
00:39:00,360 --> 00:39:04,319
Speaker 2: be the crane operator. And I was curious what kind

751
00:39:04,320 --> 00:39:06,399
Speaker 2: of money they made. And it's all over the map

752
00:39:06,440 --> 00:39:08,160
Speaker 2: if you look on the internet, because it seems like

753
00:39:08,480 --> 00:39:10,239
Speaker 2: it's just kind of hard to find that stuff out.

754
00:39:10,280 --> 00:39:14,920
Speaker 2: But I did see that in the southeastern United States,

755
00:39:14,960 --> 00:39:17,520
Speaker 2: like ninety thousand dollars puts you at about the seventy

756
00:39:17,520 --> 00:39:22,120
Speaker 2: fifth percentile. I also saw on Reddit, like my friend

757
00:39:22,160 --> 00:39:24,480
Speaker 2: os this in New York kind of thing. Yeah, but

758
00:39:24,680 --> 00:39:27,960
Speaker 2: apparently this people on Reddit are saying, in New York City,

759
00:39:28,360 --> 00:39:30,640
Speaker 2: you can make you know, two to three to four

760
00:39:30,719 --> 00:39:33,399
Speaker 2: hundred thousand dollars as like one of the top two

761
00:39:33,480 --> 00:39:35,760
Speaker 2: or three earners in New York, which, as I imagine,

762
00:39:36,239 --> 00:39:37,600
Speaker 2: the top of the game in the world.

763
00:39:38,200 --> 00:39:41,200
Speaker 1: Yeah. No, I totally believe that, like you're so in

764
00:39:41,280 --> 00:39:45,160
Speaker 1: demand that you have nothing to do with raising the

765
00:39:45,200 --> 00:39:48,920
Speaker 1: crane or taking it down. You're there as long as

766
00:39:48,960 --> 00:39:52,160
Speaker 1: they need a person to operate the crane for the job.

767
00:39:52,600 --> 00:39:55,320
Speaker 1: And then once that's done, they move you over. Somebody

768
00:39:55,360 --> 00:39:58,719
Speaker 1: hires you on another job site, like you are untouchable

769
00:39:58,880 --> 00:40:01,560
Speaker 1: as far as like the the job site's concerned.

770
00:40:01,760 --> 00:40:04,000
Speaker 2: Yeah, And in the interview, their first question is how

771
00:40:04,040 --> 00:40:05,760
Speaker 2: much fiber do you include in your diet?

772
00:40:08,400 --> 00:40:10,960
Speaker 1: So then there's a lift director. That's somebody who basically

773
00:40:11,000 --> 00:40:14,440
Speaker 1: manages the lifting that goes on. If it's a heavy

774
00:40:14,480 --> 00:40:17,560
Speaker 1: load or any kind of unique or dangerous load, they're

775
00:40:17,600 --> 00:40:20,319
Speaker 1: supposed to formulate a plan for it of how it's

776
00:40:20,360 --> 00:40:22,799
Speaker 1: going to be lifted, where it's going to go, what

777
00:40:23,000 --> 00:40:25,920
Speaker 1: direction it's going to follow, all that stuff, and they

778
00:40:26,040 --> 00:40:29,120
Speaker 1: essentially are just kind of running the show on the ground.

779
00:40:29,480 --> 00:40:31,560
Speaker 1: I believe they're usually the one.

780
00:40:31,680 --> 00:40:31,719
Speaker 3: No.

781
00:40:32,080 --> 00:40:33,480
Speaker 1: I was going to say they're the one that the

782
00:40:33,600 --> 00:40:36,480
Speaker 1: crane operator's probably in touch with, but I believe that's

783
00:40:36,800 --> 00:40:38,360
Speaker 1: the signal person instead.

784
00:40:39,120 --> 00:40:42,080
Speaker 2: That's right, And the signal person is doing just what

785
00:40:42,080 --> 00:40:46,040
Speaker 2: you think. They're on the radio and constant communication, but

786
00:40:46,080 --> 00:40:50,200
Speaker 2: they're also doing hand signals, not just on that CB

787
00:40:50,400 --> 00:40:53,719
Speaker 2: radio or whatever. They use walkie talkies and there are

788
00:40:53,800 --> 00:40:57,440
Speaker 2: times when that crane operator is working blind and they

789
00:40:57,440 --> 00:40:59,560
Speaker 2: don't have sight of what they're doing, and that's when

790
00:40:59,560 --> 00:41:03,239
Speaker 2: that signal person and really everyone working together is so key.

791
00:41:04,040 --> 00:41:06,960
Speaker 1: Yeah, that's the person who communicates to the crane operator

792
00:41:06,960 --> 00:41:08,640
Speaker 1: that the people on the ground want them to toot

793
00:41:08,640 --> 00:41:11,040
Speaker 1: their horn, right, and they use that same pull down

794
00:41:11,160 --> 00:41:14,000
Speaker 1: motion that you use for big rig truckers.

795
00:41:13,880 --> 00:41:15,719
Speaker 2: Right, or it gets the message that I have to

796
00:41:15,760 --> 00:41:18,200
Speaker 2: go potty, so let's shut everything down for forty minutes.

797
00:41:18,440 --> 00:41:21,400
Speaker 1: That's the international squeeze your knees together and hold your

798
00:41:21,400 --> 00:41:22,760
Speaker 1: crotch signal.

799
00:41:23,080 --> 00:41:27,319
Speaker 2: Uh, did you go over their rigor no? Okay, Now

800
00:41:27,320 --> 00:41:31,160
Speaker 2: that is the person who was preparing the load attaching

801
00:41:31,160 --> 00:41:33,960
Speaker 2: it to the crane hook. Obviously that load on the ground,

802
00:41:34,520 --> 00:41:36,520
Speaker 2: it's not just like, you know, just attach it there

803
00:41:36,520 --> 00:41:39,239
Speaker 2: and I'm sure it's fine. Like everything has to be

804
00:41:39,320 --> 00:41:42,520
Speaker 2: so buttoned up, like nothing can be loose or falling

805
00:41:42,560 --> 00:41:44,560
Speaker 2: off of that thing, Like it's got to be a

806
00:41:44,840 --> 00:41:46,720
Speaker 2: very nicely wrapped Christmas present.

807
00:41:47,360 --> 00:41:47,760
Speaker 3: Yes.

808
00:41:48,320 --> 00:41:52,600
Speaker 1: So, depending on where you're working, there are sixteen states

809
00:41:52,600 --> 00:41:55,440
Speaker 1: and seven cities that require you to have a license.

810
00:41:55,719 --> 00:41:59,479
Speaker 1: That's it. Everywhere else there's state or the city does

811
00:41:59,520 --> 00:42:03,799
Speaker 1: not require you to have any sort of formal training whatsoever.

812
00:42:04,840 --> 00:42:09,960
Speaker 1: The thing is, the NCCCO offers certification too, which is

813
00:42:10,040 --> 00:42:12,680
Speaker 1: usually voluntary. But I get the impression that if you

814
00:42:12,760 --> 00:42:15,799
Speaker 1: want to be one of those higher end crane operators,

815
00:42:16,040 --> 00:42:19,120
Speaker 1: you would be certified for that job multiple times over,

816
00:42:20,400 --> 00:42:24,920
Speaker 1: and not only just to kind of enhance your desirability

817
00:42:24,960 --> 00:42:28,960
Speaker 1: as an employee, but also wow, I put that as

818
00:42:29,000 --> 00:42:32,840
Speaker 1: like the HR person and to all HR people, but

819
00:42:32,960 --> 00:42:35,520
Speaker 1: also like some job sites might require you to have

820
00:42:35,560 --> 00:42:38,520
Speaker 1: at least a certification, if not a license, and it

821
00:42:38,640 --> 00:42:40,400
Speaker 1: might not even be the job site. It might be

822
00:42:40,440 --> 00:42:42,839
Speaker 1: their insurres, Like nobody's gonna be like, hey, you come

823
00:42:42,840 --> 00:42:45,600
Speaker 1: over here and operate this crane, Like you're gonna have

824
00:42:45,640 --> 00:42:47,840
Speaker 1: to have tons of experience and probably some sort of

825
00:42:47,840 --> 00:42:51,160
Speaker 1: paperwork to back that experience up. But I find it

826
00:42:51,200 --> 00:42:55,040
Speaker 1: shocking and alarming that plenty of states don't require the

827
00:42:55,040 --> 00:42:58,680
Speaker 1: person who's four hundred feet in the air lifting two

828
00:42:58,719 --> 00:43:02,640
Speaker 1: hundred tons to have some sort of formal training.

829
00:43:02,320 --> 00:43:05,479
Speaker 3: For that totally it is. It shocked me as well.

830
00:43:05,920 --> 00:43:10,520
Speaker 2: Yeah, these things are expensive to rent, you're you know,

831
00:43:10,640 --> 00:43:13,399
Speaker 2: obviously it's a cost a lot of money to build one,

832
00:43:13,480 --> 00:43:16,120
Speaker 2: but they get that money back. Because Dave just looked

833
00:43:16,160 --> 00:43:19,919
Speaker 2: up just sort of an average rental a flat top

834
00:43:20,040 --> 00:43:25,920
Speaker 2: tower crane within just an eighty eight thousand pound capacity lift,

835
00:43:25,960 --> 00:43:28,040
Speaker 2: which is I don't know how many babos that is,

836
00:43:28,040 --> 00:43:29,800
Speaker 2: but it's nowhere close to what I said earlier.

837
00:43:29,960 --> 00:43:31,800
Speaker 1: It's forty four tons.

838
00:43:31,760 --> 00:43:34,440
Speaker 2: A two hundred and sixty two foot jib arm, so

839
00:43:35,560 --> 00:43:37,839
Speaker 2: about you know, a little more than half of sort

840
00:43:37,880 --> 00:43:41,480
Speaker 2: of the maximum that that sucker is thirty five thousand

841
00:43:41,520 --> 00:43:45,600
Speaker 2: dollars a month. Yeah, the cheapest is thirty six hundred,

842
00:43:45,600 --> 00:43:47,520
Speaker 2: and that's for the one you bring on the truck.

843
00:43:48,200 --> 00:43:51,560
Speaker 1: Yeah, and a lot of those rental prices will include

844
00:43:51,920 --> 00:43:54,000
Speaker 1: putting the thing together over the course of four or

845
00:43:54,040 --> 00:43:57,439
Speaker 1: five days and taking it down too, and maybe even

846
00:43:57,520 --> 00:44:02,160
Speaker 1: a skilled crane operator depending, So you can imagine that

847
00:44:02,200 --> 00:44:06,759
Speaker 1: these things are actually fairly dangerous. Safety is far and

848
00:44:06,800 --> 00:44:09,440
Speaker 1: away like the number one concern for any crane operator.

849
00:44:09,440 --> 00:44:12,759
Speaker 1: Every single interview I've read with a crane operator, they

850
00:44:12,840 --> 00:44:15,640
Speaker 1: all were like, it's all about safety essentially, Like, yes,

851
00:44:15,680 --> 00:44:18,319
Speaker 1: you're really important on the job site, but if it's

852
00:44:18,360 --> 00:44:20,600
Speaker 1: not safe, you don't do it, Like you just don't.

853
00:44:21,719 --> 00:44:24,200
Speaker 1: I mean, you're lifting heavy loads, you're swinging them through

854
00:44:24,200 --> 00:44:26,640
Speaker 1: the air, you can drop them. There's all sorts of

855
00:44:26,680 --> 00:44:30,520
Speaker 1: stuff that can happen. And yes, wind is a big one,

856
00:44:30,560 --> 00:44:34,120
Speaker 1: as we'll see, but they've kind of figured that out.

857
00:44:34,239 --> 00:44:38,520
Speaker 1: But just the fact that there's that you have these

858
00:44:38,560 --> 00:44:41,600
Speaker 1: huge loads high up in the air. When they get

859
00:44:41,719 --> 00:44:44,360
Speaker 1: dropped or when something goes wrong, people can die, and

860
00:44:44,400 --> 00:44:48,160
Speaker 1: I mean it does happen. I remember this past July

861
00:44:48,920 --> 00:44:52,400
Speaker 1: in Manhattan, the entire jib arm of a crane fell down.

862
00:44:52,840 --> 00:44:55,839
Speaker 1: I think, I don't remember how many stories, but it

863
00:44:55,880 --> 00:44:58,799
Speaker 1: was significant. I actually I think it did kill one

864
00:44:58,840 --> 00:45:01,520
Speaker 1: person who was in a nearby apartment building, Like some

865
00:45:01,600 --> 00:45:03,879
Speaker 1: of the debris like crashed through their window and killed them,

866
00:45:03,920 --> 00:45:06,520
Speaker 1: I think. But they were the only person who died

867
00:45:06,560 --> 00:45:09,040
Speaker 1: out of this, A sixteen ton load in a jib

868
00:45:09,120 --> 00:45:11,760
Speaker 1: arm crashing to the ground in Manhattan in the middle

869
00:45:11,800 --> 00:45:12,279
Speaker 1: of a day.

870
00:45:13,040 --> 00:45:14,319
Speaker 3: That one caught on fire, didn't it.

871
00:45:14,640 --> 00:45:17,879
Speaker 1: Yeah, there was a fire in the hoist unit for

872
00:45:17,880 --> 00:45:20,120
Speaker 1: some reason. I couldn't figure out what caused it.

873
00:45:21,160 --> 00:45:25,440
Speaker 3: That's a lot that no one was killed. I mean that.

874
00:45:25,520 --> 00:45:27,759
Speaker 2: I remember when that happened too, and I was just like,

875
00:45:27,800 --> 00:45:29,680
Speaker 2: how can that happen? In New York City and not

876
00:45:29,800 --> 00:45:32,000
Speaker 2: kill like twelve people below at least, you know.

877
00:45:32,160 --> 00:45:36,040
Speaker 1: Yeah, apparently another real danger chuck is hitting power lines.

878
00:45:36,840 --> 00:45:37,800
Speaker 3: Yeah, because people.

879
00:45:37,600 --> 00:45:40,799
Speaker 1: Will walk like they'll walk like a load you know,

880
00:45:40,880 --> 00:45:43,240
Speaker 1: along to stabilize it, say, like a bunch of pipes,

881
00:45:43,840 --> 00:45:48,320
Speaker 1: and that pipe is connected via metal cable to the crane.

882
00:45:48,760 --> 00:45:51,040
Speaker 1: And if the crane came in contact with a thirteen

883
00:45:51,080 --> 00:45:54,560
Speaker 1: thousand volt power line, whoever's got their hand on that

884
00:45:54,800 --> 00:45:58,080
Speaker 1: load of pipes is it will be electrocuted. And it

885
00:45:58,120 --> 00:46:02,920
Speaker 1: happens like a lot, Like not a lot, It happens frequently,

886
00:46:03,000 --> 00:46:04,040
Speaker 1: to an alarming degree.

887
00:46:04,080 --> 00:46:07,399
Speaker 2: How about that, Well, they found some stats and what

888
00:46:07,480 --> 00:46:10,319
Speaker 2: he got was from twenty eleven to twenty seventeen, over

889
00:46:10,320 --> 00:46:13,880
Speaker 2: that seven years, they averaged forty two crane related deaths

890
00:46:13,880 --> 00:46:18,440
Speaker 2: per year. That's not insignificant, you know, forty two per year.

891
00:46:18,640 --> 00:46:23,000
Speaker 2: And I think half of those were things falling on people.

892
00:46:24,120 --> 00:46:26,440
Speaker 2: Not all of them were tower cranes. It's kind of

893
00:46:26,480 --> 00:46:31,680
Speaker 2: all cranes basically lumped together. But yeah, sometimes they're taking

894
00:46:31,680 --> 00:46:34,640
Speaker 2: it apart and it falls apart on them. It seems

895
00:46:34,680 --> 00:46:37,359
Speaker 2: like there's a lot of crushing death with it, which

896
00:46:37,400 --> 00:46:39,880
Speaker 2: is just you know, unfathomable.

897
00:46:40,320 --> 00:46:43,239
Speaker 1: Yeah, people have gotten caught in the climbing cage, caught

898
00:46:43,280 --> 00:46:46,400
Speaker 1: between that and the frame of the mast. There was

899
00:46:46,440 --> 00:46:50,200
Speaker 1: one guy who was taking a part a crane and

900
00:46:50,880 --> 00:46:54,200
Speaker 1: he was on the forty fifth story and that platform

901
00:46:54,239 --> 00:46:57,080
Speaker 1: that he was on outside the crane removing pins didn't

902
00:46:57,080 --> 00:47:01,759
Speaker 1: have a railing. It didn't have a railing, and it

903
00:47:01,880 --> 00:47:05,840
Speaker 1: shifted and he fell forty five stories because it didn't

904
00:47:05,920 --> 00:47:10,920
Speaker 1: have a railing. Wow. I just couldn't believe it. When

905
00:47:10,920 --> 00:47:13,080
Speaker 1: I read like the Oshra report, I'm just like, oh

906
00:47:13,120 --> 00:47:18,960
Speaker 1: my god, that's insanely nuts. But yeah, so safety is

907
00:47:19,080 --> 00:47:22,799
Speaker 1: extraordinarily important. You can see and I said, I tease something,

908
00:47:22,880 --> 00:47:24,920
Speaker 1: Chuck that I think you should take us home with that.

909
00:47:24,960 --> 00:47:26,800
Speaker 1: They figured out what to do in high winds.

910
00:47:27,200 --> 00:47:30,000
Speaker 2: Yeah, you know what you do in high winds is

911
00:47:30,080 --> 00:47:33,600
Speaker 2: you unbolt that thing and let it spin with the wind.

912
00:47:34,239 --> 00:47:37,080
Speaker 2: Obviously you've got the reel all the way reeled in

913
00:47:37,120 --> 00:47:40,120
Speaker 2: and it's not like swinging anything around. But when if

914
00:47:40,160 --> 00:47:45,319
Speaker 2: you see and heavy winds a horizontal arm moving, that's

915
00:47:45,360 --> 00:47:47,920
Speaker 2: what it's supposed to do. Because they have learned that

916
00:47:48,000 --> 00:47:50,800
Speaker 2: if that thing is bolted down, that puts the entire

917
00:47:50,840 --> 00:47:53,399
Speaker 2: thing at risk, whereas if you just let it move

918
00:47:53,640 --> 00:47:55,920
Speaker 2: with the wind and obviously out of the way of

919
00:47:55,960 --> 00:47:57,480
Speaker 2: hitting anything, then that's the way to go.

920
00:47:59,200 --> 00:48:02,600
Speaker 1: Yeah, and I read an interview with a crane operator

921
00:48:02,640 --> 00:48:04,960
Speaker 1: who had to ride out a storm once because it

922
00:48:05,000 --> 00:48:07,439
Speaker 1: was too dangerous to make the ten minute climb down,

923
00:48:07,719 --> 00:48:09,080
Speaker 1: so you had to sit there in the cab and

924
00:48:09,120 --> 00:48:11,600
Speaker 1: just get pushed around by the wind, letting it a

925
00:48:11,640 --> 00:48:12,239
Speaker 1: weather vane.

926
00:48:13,120 --> 00:48:14,879
Speaker 3: And I'm not even going to make a poop joke. There.

927
00:48:16,480 --> 00:48:17,279
Speaker 1: You got anything else?

928
00:48:17,960 --> 00:48:18,840
Speaker 3: I got nothing else.

929
00:48:19,360 --> 00:48:22,360
Speaker 1: This was robust. Thanks for doing it with me. This

930
00:48:22,480 --> 00:48:25,480
Speaker 1: was fun. Thanks for being the top or the bottom

931
00:48:25,560 --> 00:48:29,799
Speaker 1: to this crane episode, Chuck, Hey, anytime if you want

932
00:48:29,800 --> 00:48:32,439
Speaker 1: to know more about cranes. Apparently there's a Housetiff Works

933
00:48:32,520 --> 00:48:34,719
Speaker 1: article on it by Marshall Brain. And there's plenty of

934
00:48:34,760 --> 00:48:39,560
Speaker 1: other interesting stuff too, including really mesmerizing CGI videos of

935
00:48:39,640 --> 00:48:43,960
Speaker 1: cranes building themselves magically. And since I said that it's

936
00:48:44,040 --> 00:48:45,280
Speaker 1: time for listener mail.

937
00:48:48,280 --> 00:48:49,960
Speaker 3: All right, I'm going to call this.

938
00:48:52,360 --> 00:48:54,160
Speaker 2: Well, I'm going to call it sits scuba related. This

939
00:48:54,200 --> 00:48:58,520
Speaker 2: is kind of very poignant email. Hey, guys, been listening

940
00:48:58,560 --> 00:49:00,440
Speaker 2: for a long time. I learned to scuba with my

941
00:49:00,520 --> 00:49:03,320
Speaker 2: brother and dad when I was fourteen, back in nineteen

942
00:49:03,360 --> 00:49:06,080
Speaker 2: eighty nine, the moment we took our first breaths underwater,

943
00:49:06,120 --> 00:49:09,920
Speaker 2: we were hooked along. Aside from a long hiatus, I've

944
00:49:09,920 --> 00:49:12,759
Speaker 2: been an avid diver ever since. Many of my best

945
00:49:12,760 --> 00:49:17,120
Speaker 2: memories were created on dive trips with my brother and dad. Tragically,

946
00:49:17,160 --> 00:49:20,200
Speaker 2: we lost my brother to suicide last year after a

947
00:49:20,239 --> 00:49:24,040
Speaker 2: decade's long battle with mental illness, and I just wanted

948
00:49:24,080 --> 00:49:25,839
Speaker 2: to take a moment to commend you and your team

949
00:49:25,880 --> 00:49:28,760
Speaker 2: for your sympathy and in dexterity with which you handle

950
00:49:29,160 --> 00:49:32,239
Speaker 2: mental illness on your show. Know that the links in

951
00:49:32,280 --> 00:49:34,680
Speaker 2: which you go to assure you were using the most

952
00:49:34,719 --> 00:49:38,200
Speaker 2: compassionate language to discuss mental illness and other touchy subjects

953
00:49:38,480 --> 00:49:41,719
Speaker 2: does not go unnoticed and is greatly appreciated. But to

954
00:49:41,719 --> 00:49:43,840
Speaker 2: be clear, so are the moments you choose to essue

955
00:49:44,239 --> 00:49:48,400
Speaker 2: the acceptable standards for a moment to make a joke, Chuck,

956
00:49:48,719 --> 00:49:51,440
Speaker 2: this is for you by all means. Please get scuba

957
00:49:51,480 --> 00:49:54,640
Speaker 2: certified with your daughter and your wife if she's interested.

958
00:49:54,719 --> 00:49:57,480
Speaker 2: I have so many crystal clear, fantastic memories with my

959
00:49:57,560 --> 00:49:59,920
Speaker 2: dad and my brother diving. You can't make a child's

960
00:50:00,200 --> 00:50:02,880
Speaker 2: any more awesome than by taking them to visit another planet.

961
00:50:03,360 --> 00:50:07,000
Speaker 2: Lifetime memories are made by the moment. It's a magical pursuit.

962
00:50:07,280 --> 00:50:07,640
Speaker 3: Do it.

963
00:50:08,360 --> 00:50:10,319
Speaker 2: My brother used to say diving is easy to do

964
00:50:10,360 --> 00:50:11,360
Speaker 2: and difficult to master.

965
00:50:11,600 --> 00:50:12,080
Speaker 3: So true.

966
00:50:12,600 --> 00:50:15,479
Speaker 2: He was my friend, my die buddy, and my hero

967
00:50:16,320 --> 00:50:19,279
Speaker 2: and I miss him like crazy. He sure would have

968
00:50:19,320 --> 00:50:23,120
Speaker 2: loved the Scoob episode. And that is from Dan Man.

969
00:50:23,480 --> 00:50:25,920
Speaker 1: Dan, thank you for writing in about that. That was

970
00:50:25,960 --> 00:50:28,840
Speaker 1: really amazing stuff. I'm sorry about your brother.

971
00:50:29,480 --> 00:50:29,760
Speaker 3: Same.
