How does a crane get down from a skyscraper once they're done using it? Like the crane on top of the skyscraper, do they get take it apart?
Can only be assumed that the jibs are first dismantled then the actual crane base lowered down by a second crane or even helicopter
realdolby is correct. Small crane from parts that can be transported in service elevator is brought up and assembled. It is used to swing out and lower larger crane's parts. Then the small crane is broken apart and taken down in elevator.
