In the context of shifting loads, what does the term 'chocks' refer to?

The term 'chocks' refers to support materials designed to prevent rolling or movement of loads, particularly in the context of shifting and securing items during transport. Chocks are typically wedged or placed under the wheels of vehicles, trailers, or other heavy objects to stabilize them and ensure they remain in a fixed position. This is particularly important in situations where a load could shift due to gravity or external forces, which may lead to accidents or damages.

In contrast, other choices pertain to different functions—lifting tools are intended for raising heavy objects, packaging materials are used for wrapping and protecting items during shipping or handling, and securing straps are designed to hold down loads but do not provide the same stabilizing function as chocks. Understanding the specific role of chocks is essential for ensuring safe transportation and proper load management.
