Yo-yo, pile-up, or pilewind, hoists use yo-yo type devices instead of helically grooved drums. The yo-yos lines are coiled into overlapping layers of cable in the narrow slots. The pile-up drum hoists are usually used in low load. As the hoists are narrower than helically grooved drum hoists, these can be used in the places with limited space. Pile-up drum hoists can be mounted in many locations including ceiling, floor or wall mounting. Typical applications are to have a pile-up drum hoist with many pulleys to control a batten. Since the line is piled up on itself, this type of drum hoist provides a zero fleet angle solution.
