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

The term that best describes blocking used to support a load temporarily while at rest is cribbing. Cribbing involves the use of wooden or plastic blocks, or other materials, stacked in a way to create a stable and secure platform to support loads, particularly in construction, rigging, or heavy lifting scenarios. This technique is essential for ensuring safety during operations where equipment or materials need to be supported while not actively being moved.

In contrast, bracing often refers to structural support that is used to prevent movement rather than providing a stable base to hold a load in place. Chocks are typically used to prevent the lateral movement of items rather than to support a resting load. A support beam denotes a more permanent structure designed to hold weight but does not imply the temporary, adjustable nature of cribbing, which is specifically designed for situations where loads need to be secured or stabilized for short durations.
