the one who invented is freaking smart

thats gotta be a scary job, cool, but scary

My good friend at work, Art, has always wanted to see how cranes were actually built, excellent!!!! Thank you

Great Post. In real time, it is much like watching paint dry...unless you are on it...

If I was one of the guys on top of that I would have to bring one clean pair of fruit of the looms for each section up...

Thank you for this post as I have always wanted to see a time-lapse version of the process. Nice to have the horizon line for comparison but a little spooky to see that much flex! Don't the counter weights on the back move?

Awesome!! I love learning new things, thanks Brianfleming! The time lapse makes it even better, looks great.

this is the best video i have ever seen!

i am a crane driver too

i love cranes i am a crane driver and i love this job

its a jacking cage. it is literally 4 struts with a hydraulic jacking system. lift the top of the crane, insert tower, pin (yes, they are held by pins) next section

i was wondering how they build a crane and de build it for around 5 years and now i no

what is holding the section there when it looks like it is just stuck to the side of the tower right before it is installed?

This is so cool!

hey! you've just said what they showed on discovery channel whent there was a programme about tower cranes :D

I've been on a 25 - meter high tower crane and as it lifts sth, it moves really badly
I wonder how much it moves when it reaches over 80 meters high :O

any links ? info ?

Super interesting! well done

the reason the crane is bending is becaues the weight of the section is to great for the cranes boom at that length so you see the operator bring it in closer to the crane may stabalize. you can do this yourself by taking a small (2lb) weight and extending your arm out you will notice that you will start to go off balance and your arm will want to fall. its simple physics the closer the weight is brought in the better the crane can handle the weight

one other thing, notice how the crane bends to the left when hoisting a section at 26-29 sec., THATS CRAZY, that looks like to much flex, but im not an engineer. can someone explain this. because i know S**t gets heavier than those sections are!

today I finally saw the "sleeve myself" Im still amazed. thanks for the learning experience!!

i just finished this process last week on my tower crane in clearwater, fl...but the reverse. we dismantled 385 foot, 20 foot sections, 3 1/2 days.
tower crane operator

ok, rather you than me!. as you say human error all to frequent these days!!! thanks.

I've wondered about this in the past, very interesting. Thanks for posting.

They were building one near me recently (diferent method, another telescopic crane was used) and I've really got to hand it to those guys who've got the nerve to go climbing about on thin bits of metal away up there. I know they've got lifelines etc, butI certainly still couldn't do it!

ive been in many cranes [as im an operator in london england] and we call it a jacking frame. Remember the crane can only go at average 85meters high before it will need tieing to a building with a collar that goes round the tower. 5 Cranes have collapsed during jacking in the last couple of years and though i still sit up there when the jacking is commencing i still think its another step to far for man kind. To much room for human error.
