The CD1 type steel wire rope electric hoist is a light and small lifting hoist equipment, mainly consisting of a reducer, a running mechanism, a drum device, a hook device, a coupling, a soft cable current introducer, a limiter, and a conical rotor motor that integrates power and braking force. The following is an introduction to the safety inspection of the 8 major accessories of the wire rope electric hoist:

　　(1) Steel wire rope. Check if the specification and model of the steel wire rope match the design requirements with the pulley drum. Whether the steel wire rope fixing devices such as pressure plates, rope clamps, and wedges at the fixed end of the steel wire rope meet the requirements. Whether the wear, breakage, twisting, flattening, bending, strand breakage, corrosion, etc. of the steel wire rope exceed the standard.

　　(2) Hook. Check whether the markings and anti detachment devices of the hook meet the requirements, and whether the hook has defects such as cracks and peeling; Whether the wear of the hook section, increase in opening degree, and torsional deformation exceed the standard; Check for fatigue deformation, cracks, and related pin and sleeve wear on the neck and surface of the hook.

　　(3) Coupling. Check if there are any defects, loose connections, or running impacts on the coupling parts. Check if the wear of the coupling, pin shaft, shaft pin hole, and buffer rubber ring exceeds the standard. Is the coupling concentric with the two connected components.

　　(4) Braking device. The setting of the brake, whether the type of the brake meets the design requirements, and whether the pull rod and spring of the brake have defects such as fatigue deformation and cracks; Check if the pin shaft, spindle, brake wheel, and brake friction plate are worn beyond the standard, and if there is oil leakage in the hydraulic brake; Can the brake clearance adjustment and braking capacity meet the requirements.

　　(5) Reel. Whether there are fatigue cracks, damages, etc. on the drum body and edge; Whether the wear of the rope groove and cylinder wall exceeds the standard; Can the height of the drum flange match the number of layers of wire rope winding; Whether the working conditions of the rope guide and rope guide meet the requirements;

　　(6) Pulley. Is the pulley equipped with an anti detachment rope groove device; Check if there are cracks, broken edges, or excessive wear on the pulley groove and rim, and if the pulley rotates flexibly.

　　(7) Wheels. Check if there are fatigue cracks on the wheel tread and axle, and if the wear of the wheel tread and axle exceeds the standard. Is there any phenomenon of rail gnawing during operation. What is the cause of rail gnawing.

　　(8) Reducer. Is there any abnormal sound such as severe metal friction, vibration, and shell radiation during the operation of the gearbox; Whether the shaft end is well sealed, and whether the fixing bolts are loose or damaged; Whether the selection of lubricating oil for the gearbox, the height of the oil level, the operation of the vertical gearbox lubricating oil pump, and the lubrication of the open gear transmission meet the requirements.
