How do they get cranes down off really really tall buildings?
Beetham Tower, Manchester is the tallest residential building in the UK. I've been watching it's progress for a while. I am fascinated as to how they get the crane to the top of the building and get it down again. A friend suggested that they build the structure around it but I'm not quite sure if that'd work cos how would you get it out again?! Does anyone know? - I'm looking for any form of website that can help or even advice from a crane operator or builder. It's driving me insane trying to figure it out and now my friends are going mad trying to find out too!! The tower is 171m tall!

They dismantle the crane on the roof, and swing the parts down on a winch to a truck below, I believe.

My step brother says that they leave the crane tower inside of the building and dismatle the crane top and bring it down a piece at a time through the tower interior. The crane is mostly expendable, they only re-use the hoisting parts and the rest is scrapped out.
