1. The power unit is composed of motor, reducer, clutch, brake, rope drum and steel wire rope. The motor is a paramagnetic single-phase capacitor motor, which is designed with a mechanism of power off and braking; the motor is also equipped with a thermal switch, which can prevent the motor from burning due to overheating; the reducer is a two-stage gear reducer, which is fixedly connected to the motor; the clutch, brake and rope drum are integrated, but when the clutch is out of the state, it can realize rapid descent, and the operation of the brake can control the descent speed to avoid occurrence Impact. The round hole on the front of the power unit shell can be used to install the blower, and the user can equip the blower for forced cooling as required. 2. The bracket part is composed of a main rod and a rotating arm composed of a screw, a jack nut and a vertical rod. The rotating arm can rotate 360 degrees on the main rod, and a travel switch is set at the end of the arm to prevent the lifting over position accident caused by operation error or button failure. Operate the button starter to realize the positive and negative rotation of the motor, which can wind and release the steel wire rope, and lift and lower the object through the pulley of the support part to complete the lifting operation. Crane classification: ship crane, vehicle crane, truck crane, construction crane, etc
