How are cranes taken off buildings?
To disassemble themselves, tower cranes construct derricks on the rooftop of the finished project. (Derricks are tower cranes’ simpler great-granddaddy.) These derricks then help dismantle the tower cranes, and — in the case of internal climbers — lower their parts one by one to the ground using extremely long cables.

Do cranes have bathrooms?
When storms roll in, wind and thunderclaps shake the crane cab. (Any actual lightning strikes should pass down the crane into the ground, where the whole electrically-driven apparatus is grounded). And on top of the isolation, height and sometimes queasy crane movements, there’s the lack of a bathroom.
