Model No.: HST 5013
1) QTZ series tower crane is one of the key product of HSJJ company, which have competitive price and excellent quality, suitable for all kinds of construction projects for various kinds of work condition.
2) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m 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 moving on the horizontal rang 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 crane has scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.
