Portal Boom Crane Maintenance Guide: Professional Maintenance and Inspection

The Portal Boom Crane is a heavy-duty lifting device widely used in ports, shipyards, and large industrial facilities. Its unique portal frame structure and rotatable boom design enable efficient operation even in confined spaces. Regular maintenance is essential to ensure the long-term stable operation of the equipment. This article will provide a detailed overview of the structural components, daily inspection points, and maintenance techniques for the Portal Boom Crane, helping you extend the equipment's lifespan and enhance operational safety.

Components of the Portal Boom Crane

The Portal Boom Crane primarily consists of the following core components:

• Portal Frame: Supports the entire crane, providing strong stability; typically equipped with a traveling mechanism for mobility.
• Slewing Unit: Enables the boom to rotate horizontally, expanding the operational range.
• Boom: Performs the primary lifting tasks and is typically equipped with a boom swing mechanism to adjust the angle.
• Hoisting Mechanism: Includes steel wires, pulleys, and winches, responsible for lifting and lowering cargo.
• Electrical and Control Systems: Ensure precise operation and safety protection, such as limit switches and overload protection.

Portal Boom Crane Daily Inspection and Maintenance

1. Mechanical Component Maintenance

• Wire Ropes and Pulleys: Regularly inspect for wear, broken wires, and lubrication conditions, and promptly replace damaged wire ropes.
• Hydraulic System: Check oil levels, oil quality, and piping for leaks, ensuring hydraulic cylinders and valves operate normally.
• Bolts and Connectors: Tighten loose bolts to prevent structural loosening due to vibration.

2. Electrical System Inspection

• Cables and terminals: Inspect for aging, damage, or poor contact.
• Limit switches and sensors: Test sensitivity to ensure overload protection and travel limit functions are effective.
• Motor and brake: Inspect temperature rise and braking performance to prevent accidents caused by overheating or brake failure.

3. Lubrication and Corrosion Prevention

• Lubricate bearings, gears, and hinge points according to the manufacturer's recommended schedule.
• Regularly clean rust from metal surfaces and apply anti-rust paint, especially in humid or coastal environments.

4. Operational Testing

• After each maintenance, conduct no-load and load tests to observe for abnormal noise, vibration, or control delays.
