Description of QTZ63 Tower Crane
QTZ63 construction tower crane is one of the key product of MINGWEI company, which has good quality and competitive prices
1) The 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.
2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which enables heavy load low speed and light load high speed.
3) Wide work range and applicable objects. Through replacing, adding and removing some parts and supplementary devicesm the crane can get two working styles: independent and attached, so as to satisfy different requirements. The max. lifting height of attached style is as high as 150m.
4) The machine has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment. The crane equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limier and circumgyrating limiter, etc.
5) The crane has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field, it creates a good working environment for the operator.
