A hoist is used to perform which of the following actions?

• A. Turn a drum
• B. Run a load fall
• C. Hoist a mass
• D. Lower a load

Answer: (C)

A hoist is designed to lift loads vertically. In structural steel work, its purpose is to raise a mass into position, using a rope or chain wound on a drum or through pulleys. While the mechanism may turn a drum or allow controlled lowering, the action most characteristic of a hoist is hoisting a mass—lifting it upward to where it’s needed. Lowering or letting a load fall are separate operations or functions of other equipment or controls, not the primary purpose of the hoist.
