What is the difference between a hoist and a boom on a crane?
The term hoist means a device used for lifting or lowering a load using a drum around which rope or chain wraps. It may be manual, electrical, pneumatic or hydraulic and may use chain, fiber or wire rope with a hook (and a pulley block for heavy loads). In one word, the load-lifting part of the crane. The boom (aka jib) is part of the crane structure that provides extra reach from the center of the crane.
