ABSTRACT:
A portable conveyor assembly comprising an inclined conveyor having a lower end and an upper end. A pair of rear wheels support the lower end of the conveyor and a pair of caster wheels are spaced forwardly from the rear wheels and are suspended from a horizontal axle through vertical pivot shaft so that the caster wheels can freely rotate about the pivot shafts. An adjustable linkage interconnects between the axle and the conveyor, and a lead screw mechanism is operably connected to the linkage and acts to vary the angularity of the linkage and thus change the angle of inclination of the conveyor. A mechanism is associated with the linkage to prevent rotation of the axle and maintain the caster wheel pivot axes in a vertical attitude as the angle of inclination of the conveyor is changed.
