Lifting mechanism is mainly composed of motor, brake, reducer, drum, lifting height limiter and so on. Mounted on the rear of the balance arm, it is driven by a three-speed motor, through a transfer switch on the console, to achieve the desired lifting speed and slow emplacement accuracy. The end of the drum is equipped with a lifting height limiter. When the lifting item reaches the highest position, the lifting mechanism can stop automatically.

Rotary mechanism is mainly composed of winding motor, hydraulic coupler, electromagnetic brake, rotary limiter, planetary reducer, pinion. The mechanism is compact, the transmission is good, and the braking is stable. Work is not affected by the larger wind.

The trolley's luffing mechanism drives the deceleration device in the drum through the motor to make the trolley do the luffing movement.The mechanism is used to drive the variable amplitude trolley to reciprocate along the vertical axis of the lifting arm, so as to realize the variable amplitude movement of the hook and the lifting item. It is installed in the first arm of the crane arm and is mainly composed of a two-speed motor, a reducer, a reel and an amplitude limiter. The overall structure is compact, two variable rope is fixed on the drum after a section of winding, the other end is fixed on the trolley, when the amplitude of a retraction to ensure the normal work of the trolley.
