6T QTZ63 Tower Crane

Descriptions of Tower Crane
The 4T QTZ63 tower crane possesses a powerful lifting torque of 63 tm, its max lifting capacity is 4 tons. The max lifting capacity at its max radius of 50 meters is 1 ton. The hoisting mechanism and slewing mechanism of all tower cranes produced by Jushen adopt variable frequency technology, rendering the operation smooth and free of shock. Meanwhile, the maintenance cost of tower cranes are reduced, and the service expectancies of the structure and transmission components are extended.
