Introduction

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. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism. Most hoists couple to their loads using a lifting hook. Today, there are a few governing bodies for the North American overhead hoist industry which include the Hoist Manufactures Institute (HMI), ASME, and the Occupational Safety and Health Administration (OSHA). HMI is a product counsel of the Material Handling Industry of America consisting of hoist manufacturers promoting safe use of their products.
