Before operating a gantry crane, it is essential to ensure the safety and functionality of all components. A thorough pre-lift inspection helps prevent accidents and ensures smooth lifting operations. The key areas to inspect include:
Lifting Machinery and Equipment
Verify that all lifting machinery is in good working condition with no performance issues.
Confirm the appropriate lifting method and binding technique based on the weight and center of gravity of the load.
Ground Preparations
Assemble temporary work platforms on the ground whenever possible to minimize high-altitude assembly risks.
Check access paths, whether permanent or temporary, for potential safety hazards and address them promptly.
Load Handling Precautions
Use a single sling for lifting small items, avoiding multiple objects on a single sling.
Ensure equipment and small accessories are securely fastened to prevent them from falling during the lift.
Wire Rope Usage
Do not allow wire ropes to twist, knot, or contact sharp edges directly without protective padding.
Ensure wire ropes are kept away from electrical components.
Rigging and Load Binding
Select appropriate slings for the load, and secure all bindings firmly.
Maintain an angle of less than 90° between slings to reduce strain.
Dual Crane Operations
When using two gantry cranes for lifting, ensure each crane's load does not exceed 80% of its rated capacity.
Final Safety Measures
Attach safety guide ropes to the load before lifting.
Once the load is in place, apply temporary measures to secure it against wind or tipping before releasing the hook.
Adhering to these steps ensures the safety of personnel and the integrity of the equipment during gantry crane operations.
