Thos big cranes on top of tall buildings...

Factual Questions
1

I live in a city that is booming right now and there is a lot of construction in the downtown. How the heck do they get those big cranes on top on the tall buidings (30+ stories)? How do they get them to go up with the building? AND most importantly…how do they get it all down??

We posted on this one a month or three ago, and I’m sure its still floating around in UBBLand. However, I’m not going to try to search for it, as this computer gets all pissy when I do stuff like that.

I don’t remember seeing the thread, so I’m going to take a wild guess and say they’re bolted together in sections and can be removed by unbolting and sending it down the freight elevator piece by piece.

I remember the old thread, but I don’t feel like spending 30-40 minutes digging for it.

The cranes I’ve been watching in my neck of the woods are assembled on site by smaller cranes. And they aren’t on top of the buildings, they’re right up next to’em.
