Abstract: A rolling support for a stackable conveyor system, having a first conveying section and a second conveying section storable atop the first conveying section, comprises an axle, and first and second roller assemblies mounted on opposite ends of the axle. The axle includes a centrally mounted pivot shaft that extends normal to the axle for a pivotal connection of the axle near a rear end of a frame of the second conveying section. The first and second roller assemblies each include one or more rollers that are configured to mate with a pair of rails formed on elongate beams associated with a frame of the first conveying section. The rolling support supports the rear end of the second conveying section on the rails, with the front end and middle portion of the second conveying section frictionally supported on the rail. The rolling support allows the second conveying section to extend relative to the first conveying section once the front end of the second conveying section is elevated from the rails.
