Hoist or hoist can mean:-

A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. "Overhead" lifting operates under special legal restrictions.

For a given Rated Load wire rope is of lighter weight per running foot but is limited to drum diameters far large than the liftwheel over which chain may function. Therefore a high-performance chain hoist may be of significantly smaller physical size than a wire rope hoist rated at the same working load. High speed lifting (60 ft./min +) requires wire rope over a drum because chain over a pocket wheel generates fatigue inducing resonance for long lifts.
