A commercial driver is preparing to transport a load of coiled steel. Which of the following securement methods is specifically recommended for preventing longitudinal movement of the coils?
- AUtilizing corner protectors on tie-downs to prevent abrasion.
- BPlacing dunnage between the coils to increase friction.
- CWrapping the entire load in a heavy tarp to compress it.
- DUsing chocks and cradles to prevent rolling and movement.
Show answer & explanationAnswer & explanation
Correct answer: D. Using chocks and cradles to prevent rolling and movement.
Coiled steel, especially when placed on its side (eye to the side), has a strong tendency to roll longitudinally. Chocks and cradles are specifically designed to fit the curvature of the coils and prevent this rolling motion, thus preventing longitudinal movement.
Why the other options are wrong
- A. Corner protectors prevent tie-down damage but do not secure the load against movement.
- B. Dunnage increases friction but is not the primary method for preventing the rolling motion of coils.
- C. A tarp might offer some compression but is not a primary securement device for preventing heavy coiled steel from rolling.
Coiled Steel Securement
Specialized methods for securing heavy, cylindrical steel coils to prevent rolling and shifting.
- High risk of rolling/shifting.
- Chocks and cradles are essential.
- Tie-downs must be properly positioned and tensioned.
Memory trick: Round and heavy, cradles hold steady.
