Maintenance and Servicing of Jib Crane

To ensure the long-term stable operation of the jib crane, improve work safety, and extend the equipment's lifespan, regular maintenance and servicing are essential. Below are the key maintenance and servicing points:

1. Daily Inspection

• Structural Inspection: Check the main beam and jib for cracks, deformations, or welding defects to ensure structural integrity.
• Fastener Inspection: Regularly check bolts, nuts, and other fasteners to prevent loosening, which may cause instability.
• Hook and Wire Rope: Inspect the hook for wear or deformation and check the wire rope for broken strands, wear, or corrosion. Replace if necessary.

2. Maintenance of Moving Parts

• Rotating Mechanism: Ensure smooth operation of the rotating system. Check gears and bearings for abnormal wear and lubricate regularly.
• Track Inspection (For Mobile Type): Keep the track clean and free of obstructions to prevent wheel misalignment or damage.
• Motor and Brake System: Regularly inspect motor operation and ensure brakes are responsive and reliable for effective stopping.

3. Electrical System Maintenance

• Electrical Control System: Inspect cables for aging or damage to ensure secure connections.
• Limit Devices: Test limit switches periodically to prevent overtravel in lifting or rotation.
• Control Buttons and Remote: Ensure control buttons are responsive and the remote control signal is functioning properly.

4. Lubrication and Corrosion Protection

• Lubrication Maintenance: Regularly apply appropriate lubricants to bearings, gears, and wire ropes to reduce wear.
• Corrosion Protection: For outdoor cranes, periodically check and maintain the anti-rust coating to prevent corrosion due to environmental factors.

5. Operation and Maintenance Management

• Personnel Training: Ensure operators are trained and familiar with equipment operation standards and safety requirements.
• Regular Overhaul: Conduct monthly comprehensive inspections and annual professional maintenance, replacing worn parts as needed.
• No Overloading: Strictly prohibit exceeding the rated load capacity to avoid equipment damage or safety hazards.

By implementing proper maintenance and servicing, the operational efficiency of the jib crane can be significantly improved, ensuring safe production and reducing equipment failure rates.
