Mine Duty Drum Pulleys

Available on XT®, Tapered Bore or Q-D® Hubs.

2.MINE DUTY

Mine Duty drum pulleys were originally designed for the underground coal industry for longwall mining. Longwall conveyors have belt tensions that change depending on the varying length of the conveyor. The conveyor gets longer as it is extended along the cut in the coal seam. The uncertainty in the loading conditions leads to a conveyor pulley design that is actually stronger than the shaft it is mounted on.

Because of their heavy duty construction and proven track record in the underground industry, mine duty pulleys are often used above ground to take advantage of their added service factor. Van Gorp® standard mine duty pulleys are available in diameters ranging from 14″ to 60″ and face widths to 76″. Larger sizes available on request. Many types of lagging are available including SBR, Neoprene and Static Conductive Neoprene.

There are no ANSI/CEMA standards that govern the load ratings or material thickness of Mine Duty pulleys. The following chart compares the additional service factor that the VAN GORP® Mine Duty has compared to the ANSI/CEMA ratings for a standard pulley.
