ABSTRACT:
An ice rake and hoist are disclosed. The ice rake is suspended over an ice storage bin by two pairs of cables, one pair on each side of the rake. The cables of each pair are joined together and connected to a chain which passes over a sprocket for connection to a counterweight and winch. Both sprockets are provided on a common shaft to insure that the ice rake remains level during movement of ice into and out of the storage bin.
