QTZ40(4810) type tower crane is the latest domestic hoisting and transport machinery designed and manufactured by Zhangqiu Dacheng Machinery Industry Co., Ltd. using group technology, modular design and finite-element analysis and taking computer design platform for tower crane as the tool.

The  characteristic:

1-The ultra long arm., the coverage area is big.

2-The standard segment section is wide,rigidity is good, complete machine is stable when

    craning, swings slightly.

3-The standard segment’s principal branch is angel steel or square tube.

4-The electrical system uses domestic high quality or importing parts, performance is stable

    and reliable.

5-The standard segment , drawbar,from top to bottom turntable, and other major components,

    used in all CO2 gas-shielded welding ,penetration depth deep,small deformation..

6-Slewing mechanism adopt winding motor or frequency motor, starts smooth and reliable,

    place convenient and efficient.

7-Hoisting mechanism with good performance of speeding, lifting and declining no impact and

    smooth. 

This tower crane is a type with cantilever, bogey jib lubbing and upper slewing lifting. All its performance parameters and technical indicators have reached or are superior to the national standard. The maximum working range is 48mters; independent freestanding height 30m; adhered freestanding height 120m; rated lifting torque 400kN.m, maximum lifting capacity 4t.

This tower crane is advanced in parameters, reliable in performances, beautiful in appearance, high in quality, simple in structure and easy in operation.
