Characteristicsof QTZ315(7035) Self-erecting Tower Crane

1)QTZ315 tower cranes have competitive price and excellent quality, suitable forall kinds of construction project and can work under all kinds of workcondition.

2)This kind of crane adopts standard section hydraulic lifting and connecting,and can decide the crane height according to the actual height of the building,and at the same time the lifting capacity will not be affected; The max.attached height can reach 180m.

3)It has high working speed, good speed-adjusting performance, steady operationand high efficiency. Three-speed motor and mono-speed ratio decelerator areapplied in the lifting struction, which enables heavy load low speed and lightload high speed.

Therange-change structure drives the dolly to change range on the horizontal arm,with good positioning performance. Planet gear decelerator is applied in thecircumgyrating structure, together with moment-limiting hydraulic coupler,which can relize high load capacity, steady starting and reliable operation.

4)The crane has complete set of safety devices, which can guarantee the safe andhigh efficienct operation of the equipment. The machine is equipped withlifting height limiter, dolly range-change limiter, moment limiter, weightlimiter, circumgyrating limiter, etc.

5)Themachine has scientific layout and beautiful appearance. The operator's room isset independently on one side, with good vision field. It creates a goodworking environment for the operator.
