What weight can a single corner of a 4x4 crib stack hold?

A single corner of a 4x4 crib stack can hold a significant amount of weight, typically about 6,000 pounds. This capability comes from the structural integrity of the wooden beams and how they distribute the load across the cribbing. Crib stacks are often used in firefighting and rescue operations to stabilize loads, provide support, or create space in collapsed structures.

The weight-bearing capacity is essential for safety, ensuring that the cribbing does not fail under the weight of equipment or a trapped victim. Understanding this capacity allows responders to make informed decisions about how to effectively use cribbing in various emergency scenarios. Utilizing cribbing properly can prevent further collapses and ensure the safety of both victims and rescuers.

The options that represent lower weights do not align with the recognized standards and capabilities of properly constructed crib stacks, emphasizing the importance of knowing the correct specifications in rescue operations.
