The daily maintenance and precautions of double girder cranes are crucial to ensure their safe and efficient operation. Here are some key maintenance steps and precautions:

Daily maintenance

Lubrication and maintenance:

Regularly add lubricating oil or grease to various lubrication parts of the crane to ensure sufficient lubrication of the friction parts during operation, reducing wear and friction.

Bolt tightening:

Regularly inspect the connecting bolts, nuts, and other components of the crane to ensure that they are in good fastening condition and avoid safety hazards caused by looseness.

Electrical system inspection:

Regularly inspect the electrical system of the crane, including cables, switches, control boxes, and other components, to ensure that the electrical circuits are functioning properly and to avoid safety issues caused by electrical failures.

Wire rope inspection:

Regularly inspect the wire rope of the crane, including visual inspection and internal wire breakage inspection, to ensure that the wire rope has no obvious damage or wear, and to avoid the danger caused by wire rope breakage.

Safety device inspection:

Regularly inspect the safety devices of the crane, including travel limiters, overload protectors, power-off protectors, etc., to ensure that these safety devices function properly and reliably.

Structural component inspection:

Regularly inspect the structural components of the crane, including the main beam, legs, pulleys, etc., to ensure that these components are free from cracks, deformations, or wear, and to ensure the structural safety of the crane.

Cleaning and maintenance:

Regularly clean and maintain the crane, including removing dust, oil, and other debris, keeping the equipment clean, and extending its lifespan.

matters needing attention

Follow the operating procedures:

Operators should strictly follow the operating procedures of the crane to prevent equipment damage or safety accidents caused by misoperation.

Shutdown maintenance:

During maintenance, it is necessary to shut down and cut off the power supply to ensure safety.

Use appropriate tools:

Appropriate tools should be used during maintenance to avoid using methods such as knocking to damage the equipment.

Daily records:

When conducting daily maintenance, it is necessary to promptly record the maintenance situation, including the maintenance time, items, and personnel, in order to facilitate subsequent tracking and management.

Prohibited items:

It is prohibited to use high-speed trains and test drives for maintenance and upkeep on cranes.

Do not wipe or clean on the main beam of the crane.

Do not face away from the hatch during maintenance on the end beam.

It is prohibited to wear hard soled shoes or plastic shoes for maintenance on the crane.

Do not walk on the crane if there are parts, debris, or oil stains that have not been cleaned thoroughly.

Do not place the parts and tools that need to be replaced on the trolley or main beam.

It is prohibited to conduct live inspections and maintenance of equipment, and it is also not allowed to maintain equipment during operation.

It is prohibited to adjust the brake of the lifting mechanism with load during the test drive.
