How do you properly crib and block a load to prevent movement during lifting?

• A. Cribbing is optional if the load looks stable.
• B. Crib the load only once at the end.
• C. Use loose, off-the-shelf blocks and no chocks.
• D. Use multiple layers of solid cribbing, ensure even load distribution, place chocks or wedges where required, and verify stability before lift commencement.

Answer: (D)

Preventing movement during a lift comes down to creating a stable, multi-layered cribbing system that distributes the load evenly and locks it in place before you start the lift. Build several layers of solid cribbing, arranged so the weight rests on a square or rectangular pattern that shares the load evenly and avoids any single block bearing too much. Each layer should be solid, with no gaps or loose pieces, and the arrangement should be stable under the weight you’re lifting. Use chocks or wedges where needed to prevent forward, backward, or lateral movement, effectively locking the load against shifting as the lift begins and proceeds. Before you lift, verify the setup by gently testing for stability—there should be no noticeable movement—and keep the cribbing and chocks in place throughout the entire operation. This disciplined approach reduces the risk of cribbing failure and load movement, which are common causes of injuries and equipment damage.
