Obstacle Clearance: Remove any obstacles, debris, or unnecessary items within the crane’s operational range to ensure a clear working space and prevent collisions or damage during operation.

Ventilation and Lighting Conditions: Ensure the work environment has good ventilation and adequate lighting. In particular, good lighting is crucial for the operator’s visibility and reaction ability, especially in enclosed or poorly lit environments.

Through a meticulous environmental assessment, potential hazards can be identified, and preventive measures can be taken to avoid accidents during operation.

Safety Measures in Overhead Crane Operation

Operating an overhead crane not only depends on the equipment’s stability but also requires the operator to strictly follow safety protocols. Ensuring the safety of the equipment, the operator, and the work environment is essential to effectively prevent accidents.

Safety Operating Procedures During Operation

• Slow Start: When starting, gradually increase the load to avoid rapid acceleration or stopping, which could impact the equipment and load with excessive shock.
• Maintain Clear Visibility: Operators must have a clear line of sight to the load and the surrounding environment. If visibility is obstructed, coordination with a signal person or use of auxiliary tools is required to ensure safety.
• Single Operator Responsibility: Each lifting operation should be the responsibility of a single operator to avoid interference from multiple people, reducing the risk of mistakes.
• Monitor Load: Always monitor the load to ensure it stays within the crane’s rated load capacity and avoid overloading.
• Avoid Collisions: Avoid collisions between the load and nearby structures, equipment, or personnel, especially in confined spaces, where careful control of the load’s height and swinging is necessary.

Using the Correct Load and Load Limits

• Know the Rated Load: Operators must be aware of the crane’s maximum rated load and ensure the load does not exceed the crane’s lifting capacity.
• Avoid Overloading: Overloading is strictly prohibited as it can damage the equipment and even cause accidents.
• Proper Load Distribution: For irregularly shaped loads, ensure the load is evenly distributed to prevent tilting or loss of control.
• Regularly Check Load Limiting Devices: Ensure these devices are functioning correctly and will alarm or automatically stop the operation in case of overload.

Safe Use of the Crane’s Control System

• Familiarity with the Control System: Operators must be familiar with the control panel and all control buttons to ensure safe operation.
• Avoid Over-operation: Avoid frequent or excessive use of the control system, such as sudden lifting speeds, which could place excessive pressure on the equipment.
• Use Safety Features of the Control System: Activate and use safety features such as overload warnings, collision detection, and automatic shutdown to increase operational safety.
• Identify and Address Faults Promptly: If the control system malfunctions, stop operations immediately and inspect the system to prevent worsening issues.
