Professional Storage and Maintenance Guide for Stage Electric Hoists
Core Pre-treatment Steps Before Storage
1. Power Off and Mechanical State Reset - Storage must be performed after the equipment is completely stopped and the main power supply is cut off to avoid accidental activation of the hoist due to misoperation (confirm that the power indicator light is off and remove the key or control module). - Raise the hook to the highest position and secure it, ensuring the chain or wire rope is in a relaxed, non-loaded state to prevent metal fatigue caused by long-term stress (some high-end hoists require executing the "storage mode" program via the control panel).
2. Comprehensive Cleaning and Fault Marking
- Surface Cleaning:
Wipe off dust from the housing with a dry soft cloth. For oil stains or stage smoke residue, dilute a neutral detergent (pH 6-8) to wipe the surface, then rinse with clean water and air-dry (avoid using alcohol or corrosive solvents to prevent paint peeling).
- Faulty Equipment Management:
Post visible labels on hoists requiring maintenance (e.g., "Faulty - Pending Repair", "Forbidden to Use"), record fault phenomena (such as limit switch malfunction or abnormal chain noise), and store them separately in a maintenance area to prevent confusion and misuse.
3. Key Component Maintenance Treatment - Lubrication Maintenance:
Apply special anti-rust lubricating oil to moving parts such as chains, gearboxes, and bearings (recommended molybdenum disulfide grease with a temperature resistance range of -20℃ to 120℃). Clean old oil sludge with kerosene before application to ensure sufficient lubrication.
- Electrical Interface Protection:
Spray moisture-proof protectant (e.g., WD-40 electrical special type) on electrical components such as power interfaces and control modules, and wrap interfaces with insulating tape to prevent short circuits caused by moisture ingress.
