▪ mechanical device
      mechanical device used primarily for raising and lowering heavy loads but occasionally for moving objects horizontally. It usually consists of a block and tackle—a combination of one or more fixed pulleys, a moving pulley with a hook or other similar means of attaching loads, and a rope (or cable) between them. Motive power for a hoist may be either manual or supplied by an electric motor. Electrically powered hoists, commonly mounted to the floor or wall, are used for varied lifting and hauling operations in factories and warehouses. See also block and tackle.
