What term describes blocking used to support a load temporarily while at rest?

Blocking used to support a load temporarily while at rest is best described by the term "cribbing." Cribbing refers to the process of stacking materials, such as timber blocks, in a specific manner to create a stable support structure for loads that need to be held in place without movement. This technique is particularly essential in various construction and engineering applications where safety and stability are critical while a load is not actively being hoisted or manipulated.

The other terms relate to similar concepts of support but do not specifically denote the practice of providing temporary support in the way cribbing does. For instance, bracing typically involves providing support to prevent movement or collapse but doesn’t necessarily mean a temporary hold while at rest. Chocks are often used to stabilize objects (like vehicles) to prevent rolling but are not typically described as a block for supporting a static load like cribbing would be. Support beams refer to structural elements that carry loads over a distance but are meant for permanent or semi-permanent support rather than temporary use.
