Maintenance of underhung double girder bridge crane

Proper maintenance of an pont roulant à double poutre suspendu is essential to ensure its safe and reliable operation. Here are some key maintenance practices for an underhung double girder bridge crane:

Regular Inspections: Perform regular visual inspections of the crane components, including the bridge girder, end trucks, trolleys, hoist mechanisms, runway beams, and control systems. Look for signs of wear, damage, misalignment, or any other issues that may affect the crane’s performance. Address any identified problems promptly.

Lubrication: Follow the manufacturer’s guidelines for lubrication of the crane components. Apply lubricants to the appropriate points to ensure smooth and efficient movement of the trolleys, hoists, and other moving parts. Regularly check the lubrication levels and replenish as needed.

Load Testing: Periodically conduct load testing to verify the crane’s load capacity and performance. Load testing helps identify any potential issues with the crane’s structural integrity, hoist mechanisms, or control systems. Ensure the load testing is performed by qualified personnel following industry standards and guidelines.

Electrical System Maintenance: Inspect and maintain the electrical components of the crane, including wiring, connections, controls, and safety devices. Check for loose connections, damaged cables, or signs of electrical malfunction. Ensure that electrical systems are properly grounded and comply with electrical safety regulations.

Brake System Inspection: Regularly inspect and test the brake systems of the crane, including the bridge brakes, trolley brakes, and hoist brakes. Ensure that the brakes engage and disengage properly and that they provide adequate holding power. Adjust or replace brake components as necessary.

Wire Rope or Chain Inspection: Inspect the wire ropes or chains used in the hoist mechanisms for signs of wear, fraying, or damage. Replace any worn or damaged ropes or chains promptly to avoid potential accidents or failures.

Safety Device Testing: Test and verify the proper functioning of safety devices such as limit switches, overload protection systems, emergency stop buttons, and warning alarms. Replace or repair any faulty safety devices to ensure the crane’s safe operation.

Operator Training and Awareness: Provide proper training to crane operators on the safe operation and maintenance procedures of the underhung double girder bridge crane. Promote operator awareness of potential hazards, safe load limits, and appropriate operating practices.

Documentation and Record-Keeping: Maintain a record of all maintenance activities, inspections, repairs, and load tests performed on the crane. Keep a logbook or digital records to track the crane’s maintenance history and identify any recurring issues or trends.

It is important to consult the crane manufacturer’s maintenance guidelines and any relevant industry standards for specific maintenance requirements and schedules. Additionally, consider involving qualified maintenance personnel or crane service providers to ensure thorough inspections and maintenance practices are followed for the pont roulant à double poutre suspendu.
