<p>Material handling apparatus comprises a mobile frame (12) defining a longitudinal axis and a raised load compartment (16) on the mobile frame (12) substantially in alignment with said longitudinal axis, and having open front and rear ends (24, 26). A material handling bucket (30) is pivotally mounted to a carriage (44 or 160 or 180) mounted for longitudinal movement in an axial direction. A drive (46, 48 or 170 or 182) is provided for driving the carriage (44 or 160 or 180) bidirectionally in the axial direction. A cam surface (60, 61) is defined substantially continuous with the open front end (24) of the raised load receiving compartment (16) and continuing to a location vertically therebelow. The bucket (30) is arranged for simultaneously pivoting and riding along the cam surlace (60, 61) and the load compartment (16) in response to the movement of the carriage (44 or 160 or 180) for alternatively loading material through the open front end (24) of the load receiving compartment (16) and clearing the load receiving compartment (16) of material loaded thereupon through the open rear end (26) thereof.</p> |
