Advantages:
1): the material is Q345B Mn steel, has the superior hardness andtenacity.
2): the lifting mechanism. It adopts coiling frequency motorand mono-speed ratio decelerator, good speed-adjusting performance, steadyoperation and high efficiency.
3): the trolleying mechanism. The range-change structure drivesthe dolly to change range on the horizontal arm, with good positioningperformance
4): the slewing mechanism. Planet gear deceleratortogether with moment-limiting hydraulic coupler, which ensure highload capacity, steady starting and reliable operation
5): the hydaulic increasing mast section mechanism. and can risethe height according to the actual biulding height.
6): the safety devices. It has lifting height limiter, dollyrange-change limiter, moment limiter, weight limiter, slewing limiter, etc
