Hydraulic building hoists require regular maintenance and inspection to ensure safety and efficiency. Daily checks should include visual inspections for leaks, proper functioning of controls, and safe operation of the hoist. Monthly inspections should cover the condition of hydraulic hoses, cylinders, and seals. Annual inspections should be conducted by a qualified professional to check the structural integrity, load-bearing components, and overall mechanical condition of the hoist. Regular lubrication of moving parts and replacement of worn components are also crucial. Always adhere to the manufacturer's guidelines and local regulations for maintenance and inspection intervals.
