we’re pretty lucky to have RU-vid so one moment you can be thinking “hey, how the heck are they gonna get that down?” And then after one quick google you get an immediate answer
Thanks for posting. Those men up on top dismantling the crane - holy s**t! That's serious man's work. I ain't got the balls to get up there and do that!
I lost count how many times I have seen this take place in my city. When our city goes through a construction boom there must be over 30 towers under construction at any one time. They all use these tower cranes and they all need a large road or crawler crane to take them down. We now have our first two super tall sky scrapers nearing completion and no ground crane will be able to reach the tower cranes. That will be an interesting feat of engineering watching those impossible to reach cranes to be taken down.
I don't know which camera was used but it would have to be powered from an external source for this long duration - no normal battery pack would last that long. I've had batteries empty half-way through filming a time-lapse, it's the most annoying thing that can happen!
Aha, thanks a lot for uploading this time consuming video and it cracked all puzzles for me. What about 100 F of skyscraper??? Doing by the same dismantling techniques, huh??? Amazing also a lot of engineering and manual labour. Unbelievable. Great to have a lot of different angle videoing. LOLOLLLL BTW MERRY XMAS
OK, what about for building the Burj Kahlif? (sp). Please explain how this is accomplished. 1,918ft tall. you build a tower crane that 'grows' with the building... fine. how do you take that apart at the top?! Helicopter?
If you notice the Burj is built like a step pyramid or like a large building has a smaller building built on top and this is repeated until the final much thinner top of structure is constructed. Lower levels have roof top tower crane that reaches the top of the next roof to, then each lower level crane removes the one above. The 700 meter top level crane, is equipped to remove its own base sections, lowering it from 700 metres height to likely less than 30 metres height. Then a crane located on the roof top of floor 159, reaches the top crane and removed it to the ground, Then a lower crane removed the floor 159 crane in the same manner. I hope this made sense.
I'm not an expert but these are the main reasons I can think of: 1) the tower crane grows vertically along with the building and can lift much greater weights than the road-based crane. 2) the tower crane can lift from all points on the building site (because it's in the middle of the building!) whereas the road crane can only lift on one side. 3) The tower crane is much cheaper than a road (mobile) crane... There are many other reasons which I hope a professional could explain to us all!
You can lift way more weight. Remember, any crane needs to be counter balanced, which limits the capacity of a road side crane. Furthermore, The roadside crane can't reach all 360 degrees of the building, you'd constantly have to move it. Finally, the ANGLE of the crane would most likely put it in the way of traffic, and otherwise obstruct the area. Remember, these buildings are being constructed right in the middle of a bustling city.
Alot of reason, may be bacause of needed capacity of the crane to build that building, the reach radius or etc. Remember, no engineers will want to complicate things. They must have got their reason. Especially when involving high risk .
Tower cranes take up way less space and can service the whole jobsite way more efficiently. A mobile crane would have to sit on the street for the whole span of the project (sometimes 2 years or more) . A tower crane can be erected in the elevator shaft or on the exterior of the building and never take up any public space, such as streets or sidewalks.
Nice to see something that hasn't been ruined by music. As everyone's tastes are different, why not listen to what you like while you watch it? I'll do the same!
