Overhead cranes (also named bridge cranes) play an indispensable role in the industrial sector, offering unmatched lifting and moving capabilities. Regular maintenance is crucial for ensuring their longevity and operational safety. In this guide, we'll cover the essential daily maintenance tasks that are vital for the smooth and safe performance of bridge cranes.

Daily Maintenance Tasks for Bridge Cranes:

Exterior Inspection: A clean exterior free from dust and rust is essential. Regular checks for cracks or welding defects are necessary to maintain structural integrity.

Trolley and Hoist: Secure connections in the drive shaft seat, gearbox, and couplings ensure reliable operation. Adjusting brake wheel gaps guarantees consistent and responsive braking.

Reducer Check: Inspecting for oil leaks and unusual noises can prevent major failures. Regular assessments of bearings and gears are required for smooth operation.

Lifting Winch: Safety is paramount when inspecting wire ropes, hooks, and pulleys. Components with excessive wear should be replaced promptly, and brakes must be adjusted for secure operations.

Wire Rope Inspection: Special attention should be given to the condition of wire ropes, including signs of breakage, wear, or corrosion. Mark areas that require close monitoring for future inspections.

Lubrication: Adequate lubrication is the lifeline of moving parts. Ensuring the right quality and quantity of oil prevents wear and tear.

Pulley Maintenance: Regular checks for wear in the grooves and cracks in pulleys are crucial for safe operation.

Electrical Systems: Functioning limit switches and electrical components are critical for the crane's performance. Regular testing ensures reliability.

Coupling Inspection: Loose couplings can lead to operational hazards, making their inspection a priority.

The regular maintenance of bridge cranes is a non-negotiable aspect of operational safety and efficiency. By adhering to these daily checks and balances, companies can avoid costly downtime and extend the life span of their equipment.
