Which item is used as a lower-friction surface under a load, typically made from pipe or round stock?

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

Answer: (C)

The key idea is reducing friction to move a heavy load more easily. Rollers provide a rolling surface under the load, turning what would be hard sliding into a rolling motion. The rollers are typically simple cylindrical pieces, often made from pipe or round stock, placed under the load to create a line of contact that allows it to roll rather than slide. This setup is commonly used in rigging to shift heavy objects with less effort, and it’s usually used in conjunction with cribbing to keep the load stable and in place. Devices like pallet jacks or forklifts move loads, but they rely on powered mechanisms rather than creating a rolling surface under the load. Cribbing stabilizes and supports the load, not primarily to reduce friction. So, the best answer is rollers.
