Double beam bridge cranes are essential in various industries, including construction, manufacturing, and warehousing. These cranes are designed to lift and transport heavy loads efficiently, but improper operation can lead to serious accidents, equipment damage, and operational downtime. Ensuring safety while operating a double beam bridge crane is not only a legal and ethical responsibility but also a critical factor in maintaining productivity and protecting assets.
This article outlines essential safety guidelines to follow when operating a double beam bridge crane, ensuring smooth and secure material handling operations.
Understanding the Double Beam Bridge Crane
A double beam bridge crane consists of two parallel girders supported by end trucks and equipped with a trolley and hoist for lifting. The crane moves along a runway system, allowing for horizontal and vertical movement of loads. Due to its robust design, this type of crane is ideal for handling heavy loads and demanding applications. However, its complexity requires a disciplined approach to safety.

Pre-Operational Safety Measures
Before operating a double beam bridge crane, it is essential to conduct thorough checks and preparations to ensure a safe start:
1. Inspect the Crane and Equipment

• Conduct a visual inspection of the crane, trolley, hoist, and runway system for any visible damage or wear.


• Check for loose bolts, cracks, or deformation in structural components.


• Ensure the hoist ropes or chains are free from kinks, fraying, or corrosion.


• Verify the proper functioning of brakes, limit switches, and emergency stop controls.

2. Verify Load Capacity

• Confirm the crane's rated load capacity and ensure it is not exceeded.


• Avoid using the electric overhead travelling crane for lifting loads that are unbalanced or improperly secured.

3. Conduct Operational Tests

• Test all controls, including the hoist, trolley, bridge movement, and emergency stops.


• Check the alignment of the crane and runway system.


• Ensure warning signals, such as horns and lights, are functioning properly.

4. Assess the Environment

• Remove any obstructions from the crane's travel path and the surrounding area.


• Ensure adequate lighting and visibility in the workspace.


• Be mindful of overhead power lines or other hazards in the crane's vicinity.

Operational Safety Guidelines
When operating a double beam bridge crane, adherence to safety protocols is crucial for minimizing risks:
1. Qualified Operators Only

• Only trained and certified personnel should operate the crane.


• Operators should have a clear understanding of the crane's controls, load limits, and safety features.

2. Use Proper Signaling

• Establish clear communication protocols between the operator and ground personnel.


• Use standardized hand signals or radio communication to ensure precise instructions.


• Assign a designated signal when the operator's view is obstructed.

3. Maintain Control During Lifting

• Position the hoist directly above the load to avoid side pulling, which can destabilize the crane.


• Lift loads slowly and steadily to prevent sudden jerks or swinging.


• Avoid abrupt starts, stops, or directional changes.

4. Ensure Secure Loads

• Use appropriate lifting slings, chains, or hooks, and verify they are properly attached.


• Balance the load to prevent tilting or slipping during lifting and transportation.


• Avoid dragging loads along the floor or across obstacles.

5. Avoid Overhead Movement

• Never move loads over personnel or occupied areas.


• Ensure all workers remain at a safe distance from the load and crane.

Emergency Protocols
Being prepared for emergencies can make a significant difference in minimizing harm during unexpected situations:
1. Stop Operations Immediately

• If a malfunction or hazard is detected, stop the crane and secure the load.


• Do not attempt to operate the crane until the issue is resolved.

2. Follow evacuation procedures

• In case of an imminent danger, such as a structural failure, follow established evacuation protocols.


• Ensure all workers are accounted for and in a safe location.

3. Report and Document Incidents

• Report any accidents, near-misses, or equipment failures to supervisors immediately.


• Maintain detailed records of incidents for future reference and improvement of safety measures.

Post-Operational Safety Measures
After completing crane operations, certain steps are necessary to ensure long-term safety and equipment reliability:
1. Secure the Crane

• Park the crane in its designated position and switch off the power supply.


• Ensure the hoist and trolley are positioned securely and not left in mid-air.

2. Perform a Final Inspection

• Check the crane and equipment for any signs of wear or damage that may have occurred during operation.


• Address any maintenance needs promptly.

3. Update Maintenance Logs

• Record the crane's usage, inspections, and any issues encountered during operation.


• Schedule regular maintenance and servicing to keep the crane in optimal condition.

Key Safety Tips for Double Beam Bridge Cranes

• Always prioritize safety over speed or efficiency.


• Keep unauthorized personnel away from the crane's operating area.


• Stay updated on industry regulations and standards for crane safety.


• Continuously train and retrain operators to enhance their skills and awareness.

Conclusion
Operating a double beam bridge crane requires a proactive approach to safety at every stage of its use. From pre-operational checks to post-operational measures, each step is vital for ensuring the well-being of workers, protecting equipment, and maintaining productivity. By adhering to these safety guidelines, businesses can create a secure working environment and maximize the value of their investment in double beam bridge cranes.
