Moving diverse materials through tough conditions.Whether transporting raw coal or metals at a mine,or bulk materials and finished goods at a port,heavy (or bulk) conveyors often endure abrasivecontaminants under dirty, wet conditions that challenge component reliability.

Unlike medium conveyors, heavy conveyors are slow moving applications, so high operating temperatures and rotational speed are typically not factors affecting performance. But external temperature, heavy loads, shock loads and contaminants can significantly reduce service life for bearings and other components.
