ABSTRACT:
An apparatus for loading objects on a pallet has a first horizontal frame structure movable vertically relative to an upright support. The first frame structure supports a second horizontal frame which is movable horizontally in respect to the first frame structure. The second frame supports a carriage which is horizontally movable relative to said second frame in a direction perpendicular to the horizontal movement of the second frame and is provided with an angularly movable catching element such that said catching element by the displacement of the second frame in one horizontal direction and the displacement of the carriage in a horizontal direction perpendicular thereto may be located over an object located at a loading area within the area of said first frame structure, then lowering said first frame structure and activating the catching element, elevating said first frame structure and displacing the second frame and the carriage to the desired unloading position. If necessary the catching element is the angularly shifted and finally the first frame is lowered and the catching element de-activated.
The first frame is rectangular and is open at one end thereof and may have the second frame and the carriage thereof substituted by a shuttle table and may be provided with means to detachably receive a cross bar assembly to adapt the apparatus for transferring several objects loaded upon said shuttle table to a position above the unloading area and by means of said cross bar forcing them off the table in such position.
