Which device is a grooved wheel that changes rope direction attached to a frame?

• A. Snatch Block
• B. Hoist
• C. Fall Zone
• D. Pulley

Answer: (D)

A pulley is a wheel with a groove that guides rope and directs its path. When it’s mounted on a frame, it acts as a fixed pulley, simply changing the rope’s direction so you can pull from a convenient location without altering the load’s motion. The description fits a pulley because the key feature is the grooved wheel that redirects rope. Snatch blocks are also a type of pulley used in more complex rigging (often openable for threading rope and can function as movable blocks), hoists are lifting devices with drums and motors, and a fall zone is a safety area.
