Independent Trolley Mechanism:
It applies lightweight design, direct acts the lifting load on end carriages of trolley frame both sides. With clear force and compact layout, it has high driving efficiency, low noise, low crane height and low dead weight

Trolley Traveling Mechanism:
It is of triple compact design of motor, reducer, brake. The motor is of F insulation class, IP55 protection class, 40% load continuity rate; with thermal protection, power-distribution magnetic disk brake and reducer with hard gear surface which has been grinded or gear shaved. It’s not necessary to replace the oil in gear box during the work lifetime. It has forged wheels, wheel rim and the hardness of tread surface of HB330-380. It adopts the VVVF control speed---low speed at heavy load, fast speed at light load; adjusting range is 1:10; with stable traveling, no impacting. Trolley Limit switch adopts the cross type traveling limit switch, which can reduce the speed to zero before the collision of buffer with blocks of the rail end.
