Introduction:
Tower Crane is a machinery used for vertical lifting and horizontal delivering of building materials and any other heavy items during construction process. It can lift and lay down, horizontally shift, and rotate, so the working range is very large. The whole body can be fixed or movable.
Features:
1. 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 struction, which enables heavy load low speed and light load high speed.
2. The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
3. The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
4. Provide stepless speed regulation. Outstanding in working efficiency, operating stability and reliability,
5. This Tower Crane equipped with hydraulic lifting and connecting. The height can accordign to the actual height of the building and at the same time unchange the lifting capacity.
6. Frequency control, variable speed, smoothness and high stability, non-striking.
7. Three-speed change pole motor, simple in structure, economical ,fitting.
