Proper maintenance of cranes is crucial for ensuring their safe operation and extending their service life. Here are some key maintenance points:

1. Daily Inspections: Check for wear, breakage, or deformation in components such as wire ropes, hooks, and pulleys. Ensure all connecting bolts and nuts are tight, and inspect the electrical system wiring to ensure there are no loose or damaged connections.

2. Lubrication Maintenance: Regularly apply lubricating oil or grease to all lubrication points to ensure smooth operation of mechanical parts. Check and replace lubricating oil, especially in critical areas like gearboxes and bearings.

3. Safety Device Checks: Inspect the sensitivity and reliability of safety devices such as limit switches and brakes. Ensure all safety protection devices are functioning properly to prevent accidents.

4. Regular Maintenance: Conduct comprehensive inspections weekly and monthly, including the status of electrical equipment, steel structures, and mechanical components. During semi-annual and annual inspections, perform more detailed checks and maintenance, such as assessing the wear of control systems, main beams, and wheels.

5. Record Keeping and Evaluation: Maintenance records are essential, documenting the details of each inspection and maintenance activity. Regularly evaluate the equipment’s condition to identify and address potential issues promptly.

These maintenance measures help keep cranes in good working condition, reduce the occurrence of failures, and improve operational efficiency.
