Rigging blocks are commonly known as what?

• A. Gears
• B. Pulleys
• C. Bearings
• D. Sheaves

Answer: (B)

In rigging, the essential idea is to redirect force and create mechanical advantage using a wheel that rope runs around. A rigging block is the housing that holds that wheel and provides attachment points, and in common practice that whole assembly is simply called a pulley. The wheel inside is specifically known as a sheave, but the term pulley is the standard name for the block-and-wheel assembly used in lifting and rigging. Gears imply toothed gears for transmitting motion, bearings are rotating-support components, and a sheave refers to the wheel itself—not the entire block. So the common, correct term for rigging blocks is pulleys.
