6t Flat Top Tower Crane PT5515 QTZ80 55 Meters Jib Cranetower
Description of PT5515 Flat Top Tower Crane
This tower cranes are a modern form of balance crane that fixed to the ground on a concrete slab, 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.
