Blocking used to temporarily support a load while at rest is called what term?

• A. Pallet Jack
• B. Rollers
• C. Blocking
• D. Cribbing

Answer: (D)

Cribbing is the method of creating a temporary, stable support under a load by stacking interlocking blocks of lumber. It’s used when a load needs to stay in place and not shift or settle while work is done, so you build a solid, level base that distributes the weight safely to the ground. The interlocking arrangement and cross-bracing resist movement in all directions, which is exactly what you need for a load at rest.

Pallet jack is a tool for moving pallets, not for keeping a load from moving. Rollers help with moving or positioning a load, not with creating a stable, static support. Blocking is a general term for any piece placed under a load, but these blocks become cribbing when they’re arranged in an interlocking, braced setup to form a stable temporary support.
