Portal Boom Crane Maintenance Guide

Introduction to the Portal Boom Crane

The Portal Boom Crane is a heavy-duty lifting equipment widely used in ports, shipyards, and large industrial sites. Its unique gantry structure and rotatable jib design enable it to work efficiently in narrow spaces. Regular maintenance is very important to ensure long-term stable operation. This article will introduce the components, daily inspection, and maintenance tips of the Portal Boom Crane in detail, which will help you prolong the life of the equipment and improve operational safety.

Components of the Portal Boom Crane

The Portal Boom Crane mainly consists of the following core components. The following are the functional characteristics of each component:

• Portal Frame: Supports the entire crane and is usually equipped with a traveling mechanism to enable movement.
• Slewing Unit: Enables the boom to rotate horizontally to expand the operating range.
• Boom: undertake the main lifting task, usually equipped with a luffing mechanism to adjust the angle.
• Hoisting Mechanism: Including wire rope, pulley, and winch, responsible for lifting and lowering the cargo.
• Electrical and Control System: Precise operation and safety protection, such as limit switches and overload protection.

Daily Inspection and Maintenance Guide

1. Maintenance of Mechanical Components

Wire Ropes and Pulleys: Regularly check for wear and tear, broken wires, and lubrication, and replace damaged wire ropes in time.

Hydraulic system: check the oil level, oil quality, and pipeline leakage to ensure that the hydraulic cylinder and valve operate normally.

Bolts and connectors: tighten the loose bolts to prevent the structure from loosening due to vibration.

2. Electrical System Check

Cable and Terminal: Check for aging, breakage, or poor contact.

Limit switches and sensors: test their sensitivity to ensure that the overload protection and travel limitation functions are effective.

Motor and brake: check the temperature rise and braking performance to avoid accidents caused by overheating or brake failure.

3. Lubrication and Corrosion Prevention

Lubricate bearings, gears, and articulation points at intervals recommended by the manufacturer.

Periodically clean rust and corrosion from metal surfaces and apply anti-corrosion paint, especially in humid or coastal environments.

4. Operational Tests

After each maintenance, no-load and load tests should be performed to observe for abnormal noise, vibration, or delay in maneuvering.

Conclusion

The efficient operation of the Portal Boom Crane requires scientific maintenance management. By regularly checking the mechanical and electrical systems and doing a good job of lubrication and corrosion prevention, the risk of failure can be greatly reduced, and the service life of the equipment can be prolonged.
