Which term refers to a device used to temporarily support a load while at rest?

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

Answer: (D)

Cribbing is the method used to create a stable, temporary resting place for a load during rigging. By stacking timber blocks in an interlocking pattern, you build a flat, wide base that distributes the load and resists shifting, allowing the load to sit securely while you perform setup or adjustments. This is different from devices like pallet jacks or rollers, which are meant to move loads rather than hold them steady. Blocking can provide support as well, but cribbing specifically refers to the organized stack of blocks used to form a temporary, stable platform for a load. Always use sound lumber, place on solid ground, and ensure the stack is stable before relying on it.
