Question 1

What is the purpose of shoring? Explain how you would use it.

Answer 1

Shoring is used to protect the cargo floor and to distribute load pressure over a greater area on the floor. Shoring can often make the ifference between being able to carry a given load and not being able to; however, it is important not to exaggerate the effectiveness of shoring. Some vehicles have a tread width too narrow to allow the wheels to rest on the treadways. In this case, shoring must be used to reduce the contact pressure on the walkway to an allowable weight limit. In general, shoring is required for all wheeled platforms and dolliesand for any item of cargo whose contact pressure exceeds the floor limitations.
