How do they put cranes to the upper floors in the building of skyscrapers?
You see cranes to the floor that can increase around 50 meters, however sometimes, when building high skyscrapers, cranes me into your 70th floor or 80th floor to see. How she as result high upward the crane since it can simply go around 60-70 gauge high?

The cranes were built in the elevator shafts and moves as needed during work progress.
These cranes are self-raising.
As they need to go higher they raise on hydraulic jacks and another part is screwed into the hole that remains. I hope this answer your question
