Maintenance and Care of Marine Cranes

The maintenance operation of ship-mounted cranes is crucial. To ensure their safe and efficient operation, here are a series of maintenance steps and suggestions:

Regular Inspection

1.Conduct a comprehensive inspection of the crane, including key components such as mechanical structures, electrical systems, steel wire ropes, pulleys, bearings, etc.

2.Examine the crane for damage such as rust, wear, or cracks.

3.Ensure that the safety protective devices of the crane, such as limiters and overload limiters, are intact.

Lubrication and Cleaning

1.Regularly lubricate various parts of the crane to reduce wear and friction.

2.Clean the surface and interior of the crane to remove oil stains and dust, ensuring the equipment is clean.

Steel Wire Rope Maintenance

1.Inspect the steel wire rope for wear, broken wires, and rust, and replace damaged steel wire ropes promptly.

2.Keep the surface of the steel wire rope clean to prevent rusting.

3.Regularly lubricate the steel wire rope to reduce wear.

Electrical System Inspection

1.Check if the electrical wiring is intact and free from damage or aging.

2.Examine if electrical components such as motors and controllers are working properly.

3.Ensure reliable grounding devices to prevent electrical shock accidents.

Fastener Inspection

1.Inspect if the fasteners of the crane are loose, such as bolts and nuts.

2.Tighten loose fasteners promptly to prevent accidents caused by equipment loosening.

Function Testing

1.Conduct no-load and load tests on the crane to check if its functions such as lifting, luffing, and rotation are normal.

2.Test the braking performance of the crane to ensure it is safe and reliable.

Recording and Reporting

1.Record the details of each maintenance session, including inspection items, identified issues, and corrective measures taken.

2.Report major faults or issues to superiors promptly and take corresponding measures for handling.

By following these maintenance procedures, the safe and efficient operation of ship-mounted cranes can be ensured, prolonging their service life, reducing failure rates, and providing strong support for the normal operation of ships.
