What measures help prevent load rotation or side load during hoisting?

• A. Use a single sling to simplify the setup.
• B. Use multiple slings symmetrically, a spreader or lifting beam, and ensure the load’s CG aligns with the hoisting point; monitor orientation during lift.
• C. Attach the load directly to the hook without spreader or slings.
• D. Rotate the load during lift to verify balance.

Answer: (B)

Preventing load rotation and side loading comes down to keeping the lifting force balanced and distributed so it acts through the load’s center of gravity. Using multiple slings arranged symmetrically shares the weight evenly and reduces any single-point moment that could tip or twist the load. A spreader bar or lifting beam helps maintain the proper geometry, keeps the slings in the right planes, and prevents the load from twisting or bending the lifting point. When the load’s center of gravity is aligned with the hoisting point, the lift creates minimal rotational moments, helping keep the load oriented correctly as it rises. Monitoring the load’s orientation during the lift lets the operator detect any undesired rotation early and adjust before side loading or tipping occurs.

Single sling setups tend to introduce tilt and rotation because the force isn’t distributed or aligned with the CG. Attaching directly to the hook without a spreader or slings concentrates the force at a single point, increasing the risk of rotation and side loading. Rotating the load during the lift is not a preventive measure and can destabilize the rigging.
