Abstract: Material handling apparatus comprises a mobile frame defining a longitudinal axis and a raised load compartment on the mobile frame substantially in alignment with said longitudinal axis, and having open front and rear ends. A material handling bucket is pivotally mounted to a carriage mounted for longitudinal movement in an axial direction. A drive is provided driving the carriage bidirectionally in the axial direction. A cam surface is defined substantially continuous with the open front end of the raised load receiving compartment and continuing to a location vertically therebelow. The bucket is arranged for simultaneously pivoting and riding along the cam surface and the load compartment in response to the movement of the carriage for alternatively loading material through the open front end of the load receiving compartment and clearing the load receiving compartment of material loaded thereupon through the open rear end thereof.
