How are tower cranes attached to buildings?
The tower crane shaft has a ladder that winds up the center of it. If you look closely at the photos posted above, you can see them. When a crane is standing alone on a construction site, the crane operator climbs the ladder to the operator’s cab. Once the building starts to climb and the crane with it, the crane operator can use the construction elevator instead, which is attached to the side of the building much like the crane is. Then the operator can just climb into the tower crane shaft to the last few feet to the cab.
