Regular maintenance of a hydraulic building hoist is crucial for safety and efficiency. Key requirements include inspecting and lubricating moving parts, checking for leaks in hydraulic lines and seals, ensuring the hoist's load limit is not exceeded, and verifying the operation of safety devices like limit switches and emergency stops. Additionally, the hydraulic fluid should be checked for contamination and changed as needed, typically every 1000 hours of operation or annually. The electrical system should be inspected for any damage or wear, and all controls should be tested for proper functionality. A thorough inspection by a qualified technician is recommended at least once a year to ensure all components are in compliance with safety standards.
