Pile-up or Yo-yo hoists allow the lift line to wrap on top of itself in a narrow slot. This type of hoist is normally used for low loads in applications such as banner hoists.
Pile-up or Yo-yo hoists allow the lift line to wrap on top of itself in a narrow slot. This type of hoist is normally used for low loads in applications such as banner hoists. They may also be used when there are space problems that preclude the use of drum type hoists.
The wire rope winds on top of itself, changing the effective diameter of the drum, causing the lifting speed to change as the drum turns. The change in speed may make these hoists unacceptable for some applications. There is some crushing of the wire rope as it winds on itself, leading to higher wear than a wire rope in a grooved drum.
