1.suitable for all kinds of construction project and can work under all kinds of work condition.
2.It has high working speed, good speed-adjusting performance, steady operation and high efficiency.
3.The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment.
4.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.
5.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.
>>>Feature&Advantage of the Tower Crane:
| 1 | Torque limiter | it will warns when lifting weights reach to 90% of rated lifting torque. When reach to 110% of the rated lifting torque, it will limit rising upwards and trolley. |
| 2 | Weight limiter | Control the maximum lifting capacity, lifting weight reach to 40% of the rated capacity, limit high-speed lifting; lifting weight reach to 110% of the rated capacity, limit the lifting up. |
| 3 | Height limiter | Control the lowest and highest extreme position of lifting hook. |
| 4 | Slewing limiter | Control the extreme turns number of turn left and right. |
| 5 | Amplitude limiter | Control trolley limit position of inward and outward. |
| 6 | Overload protection | If the material is over the capacity, the crane will give a sharp warning for protection itself. |
| 7 | Emergency brake | If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure. |
| 8 | Control Method | Room control or remote control to avoid any injury to the operation staff. |
| 9 | Main lifting motor | with thermal protection and currency protection. |
