ABSTRACT:
A conveyor system includes an extension section that slides inwardly and telescopes outwardly of a main section of conveyor. The extension motion is powered by at least one hydraulic ram. The conveyor has a stem that lowers to a loadable height by the retraction of double hydraulic rams upon a steel internal core. The conveyor then lifts vertically in a cantilevered manner upon a vertical ram and then rotates 360 degrees parallel to the plane of a truck bed using a cooperating gear plate and a hydraulic motor with a chain. Paddles push material secured to a chain drive or alternately a belt and the chain drive or belt moves through a series of sprockets or rollers in a continuous manner. The paddles eventually return to their initial location.
