Slab cranes and tower cranes are widely utilised in the construction of tall buildings and are attached in different floors as the building rises. They are unique as they can scale the building as it climbs. Tower cranes can add their tower segments when armed with a climber section. The climber enables the crane to jack up the tower enough to add 1 part of tower per movement.
The climber section also provides the crane with the ability to reduce its self-back down the side of a structure when the construction is completed. Once it’s at a lower altitude, a mobile crane can disassemble the crane and load it out till it is gone as though it was never there.
