Brake system in the lifting mechanism is arranged on the brake cylinder, so as to turn in a hydraulic motor,agricultural bearings , brake lock lifting hydraulic motor. At the same time in the brake cylinder into the oil passage is provided with a one-way throttle valve, and its role is to enable the brake brake fast, slow release the brake.
The former is to enable the motor to brake quickly, quickly stopped falling weight. The latter is when the load lifting process again in mid air,mobile crane bearing , avoid heavy weight of the hydraulic motor drag inversion and produces transient downhill phenomenon.
