What is the maximum average box crib slope for lifting and moving?

The maximum average box crib slope for lifting and moving is typically established at 10%. This slope is crucial for maintaining stability and safety during rescue operations involving structural collapse scenarios. A slope of 10% ensures that the cribbing is secure and that the load is adequately supported, minimizing the risk of shifting or failure under weight.

This consideration is essential in rescue operations where personnel may be working in uncertain environments, as any excessive angle could lead to potential instability of the cribbing system, making it hazardous not only for the load being lifted but also for the rescuers involved. Thus, adhering to this 10% limit helps ensure efficient and safe lifting operations.
