Abstract

A chain guide for a driving chain of a winning plow or the like, the chain guide being provided with a chain guide element which is arranged in spatial proximity to the sprockets at a driving or return station and is against the chain transversely to the direction of movement of the latter, provision is made according to the invention for the chain guide element to have at least one pressure roller which can be adjusted against the chain links of the driving chain, as a result of which the wear on the chain guide element is considerably reduced.
