QTZ80 External climbing Tower crane 8t max.load for high building construction
Description:
External climbing tower cranes are a modern form of balance crane that fixed to the ground on a concrete slab (and sometimes attached to the sides of structures), tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall buildings.
The base is then attached to the mast which gives the crane its height. Further the mast is attached to the slewing unit (gear and motor) that allows the crane to rotate.
On top of the slewing unit there are three main parts which are: the long horizontal jib (working arm), shorter counter-jib, and the tower head.
