The features of QTZ31.5(3808) of self-lifting hammerhead mini tower crane QTZ31.5
1) QTZ31.5 tower crane has competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.
2) It 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 121m.
3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator is applied in the lifting mechanism, which enables heavy load low speed and light load high speed.
4) The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance.
5) Planet gear decelerator is applied in the slewing structure, together with moment-limiting hydraulic coupler, which cans realize high load capacity, steady starting and reliable operation.
6) The crane has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, slewing limiter, etc.
7) The machine has scientific design 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.
8: Application field: Building height up to 40 floors (121m), loading capacity up to 3t, jib length is 38m or little more. If you have special requirements, we will design new tower crane for you.
