Overview
Balancing loads is essential for safe and efficient lifting. Poor load balancing can cause the crane to tip, the load to sway, or the rigging to fail. Ensuring correct load balancing is key to maintaining crane stability and preventing mishaps.
1. Calculate the Load’s Center of Gravity
A load’s center of mass must be identified and accounted for before lifting. An unbalanced load. Align the crane’s lifting point with the load’s center of gravity. This will help prevent swaying, tipping, and shifting during the lift.
2. Use Appropriate Rigging Techniques
The way the load is rigged plays an essential part in keeping the load stable during lifting. Use rigging tools like slings, spreader bars, and shackles to help distribute the load evenly. The right rigging setup is critical for maintaining load stability and ensuring a safe lift.
Be Cautious with Asymmetrical Loads
Asymmetrical loads can pose a unique challenge for balancing. If lifting an asymmetrical load, make sure to adjust the rigging to compensate for the uneven weight distribution.
Improperly balanced asymmetrical loads can easily shift, leading to accidents or equipment damage.
4. Perform a Test Lift to Check Balance
Before fully lifting the load, do a small lift to verify that the load is stable and won’t shift. A trial lift helps ensure that the load is secure and balanced before proceeding with the full lift. Use the test lift to make sure the load is evenly distributed and properly aligned with the crane’s lifting point.
5. Communicate with the Crane Operator and Crew
Clear communication between the rigger and the crane operator is essential for preventing accidents during the lift. Use hand signals or radios to coordinate movements and ensure the operator knows when to lift, stop, or adjust the crane. Keeping the entire crew informed ensures the load remains balanced and stable throughout the lift.
