Maintaining a building hoist involves regular inspections, lubrication, and repairs. Ensure all safety features are operational and that the hoist is clean and free of debris. Check cables for wear and replace them if necessary. Lubricate moving parts as per the manufacturer's recommendations. Inspect the electrical system for any signs of damage or wear. Regularly test the hoist's load capacity and emergency stop functions. Keep a maintenance log to track all inspections and repairs. If any issues are identified, address them promptly to prevent accidents and ensure the hoist operates safely and efficiently.
