Description of QTZ series tower Crane
- QTZ series tower crane adopts standard section hydraulic lifting and connecting.
-
The max. height of crane can reach 180m -200m with wall tie ins.3) 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 construction, which enables heavy load low speed and light load high speed.
The range-change structure drives the trolley cart moving on the horizontal lifting jib, with good positioning performance. Planet gear decelerator is applied in the circumventing structure, together with moment-limiting hydraulic coupler, which can realize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficient operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.
