Abstract: A belt support apparatus for supporting a conveyor belt may include at least one support arm assembly operably connected to a base member. A slider bar having a belt support surface for supporting the conveyor belt is connected to a distal end portion of the at least one support arm assembly. In one form, the support arm assembly is configured to allow the belt support surface of the slider bar to be moved relative to the base member in different lateral and vertical positions via a plurality of different modes of adjustment. The plurality of different modes of adjustment may include movement of the slider bar in an arcuate path relative to the base member and translational shifting of the slider bar, including in an oblique direction that extends obliquely relative to a vertical direction and a lateral direction perpendicular to a conveyor belt travel direction.
