Abstract

A trim chain guard assembly mounted on a mining machine configured to protect the trim chain from mined material directed against the trim chain at at least one of the non- cutting sections along the trim chain path of travel. The present invention is also directed to miners comprising a trim chain and at least one rotor arm for breaking mined material away from a target surface. The mined material broken from the target surface is directed toward the trim chain thereby potentially damaging the trim chain. The miner further comprises a guard positioned to at least partially cover the trim chain blocking at least some of the mined material directed to the trim chain by the at least one rotor arm.
