Maintenance Points

Ensuring Long-Term Performance

To maintain overhead crane performance, regular maintenance is essential:

• Keep the crane clean, free of dust, and inspect for cracks to ensure reliable operation.
• Adjust brake wheel clearance for even and sensitive braking performance.
• Check the reducer for oil leaks or abnormal sounds, inspecting bearings and gear meshing for durable performance.
• Inspect wire ropes, hooks, and pulleys for safe lifting, replacing worn components as needed.

Operational Precautions

Safe Operation Guidelines

For safe and efficient overhead crane operation:

• Conduct no-load tests to verify wire rope, hook, limiter, rope guide, and electrical components.
• Ensure no personnel stand under the hook and restrict non-operators from the work area.
• Operators must focus on tasks, coordinating closely for safe material lifting.
• Avoid overloading and prevent hands from being caught between wire rope and cargo.
• Regularly lubricate wire ropes with clean oil, avoiding manual application for safety.
• Perform routine checks and replace worn wire ropes to maintain secure operation.

Troubleshooting Common Issues

Addressing Faults

The Low-Headroom Single Girder Bridge Crane may encounter issues. Common faults and solutions include:

• Low Voltage – If the motor fails to reach operating speed due to low grid voltage, increase the voltage appropriately.
• Gearbox Faults – If the hoist fails to rotate under load, remove the load to test the motor. If functional, inspect the gearbox or transmission mechanism.
• Blown Fuse – Replace a blown power fuse to restore proper motor function and avoid single-phase operation.
