To maintain and repair a building hoist, follow these steps: Regularly inspect the hoist for any signs of wear and tear or malfunction. Lubricate moving parts as per the manufacturer's recommendations to reduce friction and prevent rust. Check and replace worn cables, pulleys, and other components. Ensure that safety devices like limit switches and emergency stops are functioning correctly. For repairs, address any mechanical failures, replace broken parts, and make sure the electrical system is in good condition. Always follow the manufacturer's guidelines and consult with a professional if the issue is complex or beyond your expertise. Regular maintenance and prompt repairs can extend the life of the hoist and ensure safe operation.
