The appearance and protection inspection of stage electric hoists is crucial for ensuring their safe operation and performance. The following are some key inspection points: Key Points for Appearance Inspection 1. **Housing** - Check whether the housing of the electric hoist has deformations, cracks, damages, etc. These may affect its structural strength and protective performance. - Examine whether the coating on the surface of the housing has peeling, rusting, corrosion, etc. If any of these exist, they should be dealt with in a timely manner to prevent further damage. 2. **Steel Wire Rope** - Observe whether the appearance of the steel wire rope has defects such as broken wires, wear, deformation, and rust. If the number of broken wires exceeds the specified amount or the wear reaches a certain degree, it will seriously affect the load - bearing capacity of the steel wire rope, and it should be replaced in a timely manner. - Check the lubrication condition of the steel wire rope. If the surface of the steel wire rope is dry and lacks oil, it will increase wear, and regular lubrication should be carried out. - Check whether the winding of the steel wire rope on the drum is neat, and whether there are phenomena such as disordered ropes and overlapping ropes. If so, it will affect the service life of the steel wire rope and the normal operation of the electric hoist. 3. **Hook** - Check whether the hook has cracks, deformations, wear, etc. If the wear of the dangerous section of the hook exceeds the specified value, it will reduce the load - bearing capacity of the hook, and it must be replaced. - Examine whether the anti - detachment device of the hook is in good condition. The anti - detachment device should be able to effectively prevent the lifted object from detaching from the hook. 4. **Rope Guide** - Observe whether the rope guide has wear, deformation, damage, etc. The function of the rope guide is to guide the steel wire rope to be neatly arranged on the drum. If it is damaged, it will cause the steel wire rope to become disordered. 5. **Motor** - Check whether the motor housing has phenomena such as overheating, discoloration, and damage. Motor overheating may be caused by reasons such as overload and poor heat dissipation, and the fault should be investigated in a timely manner. - Examine whether the junction box of the motor is well - sealed, and whether there is moisture or water ingress, to prevent electrical short - circuit faults. 6. **Brake Device** - Check whether the surface of the brake wheel has wear, cracks, oil stains, etc. The oil stains on the surface of the brake wheel will affect the braking effect, and wear and cracks will reduce the strength of the brake wheel. - Observe the wear condition of the brake shoe of the brake. If the wear of the brake shoe exceeds the specified value, it should be replaced in a timely manner to ensure reliable braking. Key Points for Protection Inspection 1. **Limit Device** - Check whether the upper and lower limit devices of the electric hoist are sensitive and reliable. The electric hoist can be manually operated to rise and fall, and observe whether the limit device can accurately stop the operation of the electric hoist at the specified position. - Examine whether the installation of the limit switch is firm, and whether there is looseness, displacement, etc., to ensure that the limit switch can work normally. 2. **Overload Protection Device** - Check whether the overload protection device is working properly. By simulating an overload situation, observe whether the overload protection device can be triggered in a timely manner to stop the lifting action of the electric hoist. - Examine whether the components such as sensors and controllers of the overload protection device are damaged or loose, to ensure that it can accurately detect the overload signal. 3. **Grounding Protection** - Check whether the grounding of the electric hoist is good. The grounding resistance should meet the requirements of relevant standards, and a grounding resistance tester can be used for measurement. - Examine whether the grounding wire has damage, breakage, looseness, etc., to ensure the reliable connection of the grounding wire. 4. **Guardrails and Safety Nets** - Check whether the guardrails and safety nets around the stage electric hoist are firmly installed, and whether there are deformations, damages, or missing parts. The height and spacing of the guardrails and safety nets should meet safety requirements. - Ensure that the guardrails and safety nets can effectively prevent people and objects from falling from heights, and protect the safety of people and equipment. 5. **Electrical Protection** - Check whether the electrical system of the electric hoist has a leakage protection device. The leakage protection device should be able to quickly cut off the power supply in case of a leakage fault to protect the safety of personnel.

- Examine whether the insulation of the electrical circuit is good, and whether there are damages, aging, moisture, etc., to prevent electric shock accidents.
