A conveyor coupled to a skid motor vehicle operates to unload bulk granular material from a railroad hopper car. The conveyor has an obtuse configured frame supporting an endless belt extended about an idler roller and a driven roller. A hydraulic motor mounted on the frame supplied with hydraulic fluid under pressure from the hydraulic system of the motor vehicle rotates the drive roller thereby moving the belt relative to the frame and mount thereon. A pair of transverse tubular box members are secured to the bottom of the frame to accommodate forks attached to the skid motor vehicle whereby the skid motor vehicle can lift the conveyor and transport it to another location.
