Main Parameters for Tower Crane
1 | Torque limiter | Control torque, 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 |
