Check whether the grounding system of the motor is reliable. If the rust is serious, rust removal should be carried out. 4. Check the worm gear reducer, safety coupling and clutch. Remove grease and add gear oil. Check the wear of the worm gear and worm, and replace it when the gear is thin or grooved. Safety couplings must not be loosened or adjusted easily. 5. Carefully check that the lock nut buckle of the wire rope should not have defects such as broken heads and loose sleeves. The wire rope itself should not have bias, loose strands, broken wires, hard injuries, dents, rust and obvious wear and tear. Pay particular attention to the rope divider and the wire rope clamps. In order to prevent the wire rope from rusting and reduce the wear between the wire rope and between the wire rope and the reel and pulley, the anti-rust grease can be applied to the wire rope with a stiff brush. 6. Check the limit switch and check whether the power cable is under pressure, clamped or damaged.
