ABSTRACT:
A chain guide for guiding a chain within a chain hoist. The chain guide includes a substantially elongated body having an inner side and an outer side, along with first and second extremities. The substantially elongated body is made of a substantially flexible material for curving the substantially elongated body into a substantially arched configuration about a given wheel of the chain hoist. The chain guide also includes first and second chain receiving portions provided adjacent to the first and second extremities respectively of the substantially elongated body, on the inner side thereof. Each chain receiving portion comprises a pair of shoulders protruding from the inner side of the body and defining an open channel shaped and sized for slidably receiving a portion of the chain. The chain guide also includes a deformable connecting portion for interconnecting the first and second chain receiving portions of the chain guide. Also described is a chain hoist provided with the chain guide.
