Operating Procedures for Bridge and Gantry Cranes - DQCRANES

Bridge and gantry cranes are essential equipment for lifting and moving heavy loads in various industries. These cranes are used in manufacturing facilities, warehouses, construction sites, and other industrial settings. To ensure the safe and efficient operation of gantry and bridge cranes, it is important to follow proper operating procedures. In this blog post, we will discuss the key operating procedures for bridge cranes and gantry cranes to ensure the safety of personnel and equipment.

Pre-Operation Inspection

Before operating a bridge or gantry crane, it is crucial to conduct a pre-operation inspection to ensure that the crane is in good working condition. The pre-operation inspection should include checking the following components:
 

• Structural Integrity: Inspect the crane structure for any signs of damage, such as cracks or corrosion. Ensure that all structural components are in good condition and free from defects.
• Hoist and Trolley: Check the hoist and trolley for proper functioning, including the brakes, limit switches, and load-bearing components. Ensure that the hoist and trolley are free from any obstructions and are properly lubricated.
• Controls and Safety Devices: Test the controls and safety devices, such as limit switches, emergency stop buttons, and overload protection systems. Ensure that all controls are functioning properly and are clearly labeled.
• Electrical Components: Inspect the electrical components, including wiring, connectors, and power supply systems. Check for any signs of wear or damage and ensure that all electrical connections are secure.
• Load-Handling Equipment: Inspect the slings, hooks, and other load-handling equipment for any signs of wear or damage. Ensure that the load-handling equipment is suitable for the intended load and is in good working condition.

Operating Procedures

Once the pre-operation inspection is completed and any issues are addressed, the following operating procedures should be followed when operating a gantry or bridge crane:
 

• Personnel Training: Only trained and authorized personnel should operate gantry and bridge cranes. Operators should be familiar with the specific crane model they are operating and should be trained in safe operating procedures.
• Load Capacity: Before lifting any load, verify that the crane can safely lift and move the load. Consult the crane's load capacity chart and ensure that the load does not exceed the crane's rated capacity.
• Clear Communication: Establish clear communication between the crane operator and any personnel involved in the lifting operation. Use hand signals, two-way radios, or other communication devices to ensure that everyone is aware of the lifting operation.
• Clear Pathways: Ensure that the area where the crane will be operating is clear of obstructions, including personnel, equipment, and materials. Clear pathways should be established to prevent any interference with the crane's movement.
• Safe Lifting Practices: Use proper rigging techniques when attaching loads to the crane's hook or lifting attachments. Ensure that the load is properly balanced and secured before lifting.
• Avoid Sudden Movements: Operate the crane with smooth and controlled movements to prevent sudden jerks or swings of the load. Avoid abrupt starts and stops to maintain stability during lifting operations.
• Overhead Clearance: Be mindful of overhead obstructions, such as beams, pipes, or other structures, when operating a gantry or bridge crane. Ensure that there is adequate overhead clearance for the crane and the load being lifted.
• Emergency Procedures: Familiarize yourself with the crane's emergency procedures, including how to safely lower a load in the event of a power failure or equipment malfunction.

Post-Operation Procedures

After completing a lifting operation with a gantry or bridge crane, it is important to follow post-operation procedures to ensure that the crane is properly secured and ready for future use. The following post-operation procedures should be followed:

• Shutdown Procedures: the gantry crane should be parked on the shutdown line, secured with clamps, and the hook raised to the upper position; the bridge crane should park the trolley between the two tracks with the hook raised. No load should be suspended from the hook.
• After operations: Set the controller to zero, disconnect the power, and securely close and lock the control room doors and windows.
• Post-Operation Inspection: Conduct a post-operation inspection to verify that the crane is in good condition and free from any damage or issues that may have occurred during the lifting operation.

Additional Considerations

• Specific load requirements: Follow any special handling procedures for hazardous or delicate loads.
• Weather limitations: Adhere to wind speed and other weather-related restrictions.
• Training: Provide regular operator training and refreshers on safety procedures.
• Maintenance: Implement a comprehensive maintenance program to prevent equipment failures.

By following these operating procedures for gantry and bridge cranes, operators can ensure the safe and efficient operation of these essential lifting devices. It is important to prioritize safety at all times when operating gantry and bridge cranes to prevent accidents and injuries in industrial settings.
