Question: 1 / 400

What is the weight rating of a 3 by 3 box used for cribbing?

50,000 pounds

55,000 pounds

The weight rating of a 3 by 3 box used for cribbing is determined by its ability to support substantial weight safely. In the case of a 3 by 3 box composed of solid wood or a similar robust material, the 55,000-pound rating reflects the designed load-bearing capacity for safe use in scenarios such as stabilizing vehicles or heavy machinery. Cribbing is critical for ensuring safety in lifting and stabilizing operations; thus, an understanding of these ratings is essential for any personnel involved in such tasks.

While the other choices represent high weight capacities, they exceed the standardized rating for this specific size of cribbing. Using a box rated higher than necessary might lead to a false sense of security, but engineers and safety guidelines are based on tested and confirmed ratings; therefore, recognizing the correct rating is vital for operational safety and efficiency.
