Background technique

The hoisting mechanism is a device for lifting and lowering heavy objects. In construction machinery, as shown in Figure 1, the hydraulic motor is often used to drive the reducer to drive the winch drum to work. During normal operation, the pressure oil source outputs oil through the control valve 4, and the balance valve controls the winch motor 1 to rotate. At the same time, the hydraulic control valve 3 controls the opening of the brake cylinder 2, and the hydraulic motor 1 moves bidirectionally to complete the lifting and lowering of the winch, thereby ensuring that the motor rotates and lifts heavy objects under the drive of the oil.
