how do they get the construction crane onto the the tall buildings?
If the crane has a mountaineering physique it is going to diminish itself down, removing its very own tower sections till it somewhat is low adequate to be bumped off by potential of a cellular crane. If it doesnt a smaller crane stated as a derreck crane would be set up on the roof of the development, it is going to take the tower crane dowm, as quickly because it somewhat is bumped off the derreck crane is disassembled and taked down by potential of the homes raise
There are two cranes, one lifts the other and construction workers build a scaffold under it. Then the higher crane lifts the lower one and the workers buiold a scaffold under it, this continues until they are as high as they need to be.
