ABSTRACT:
Powered material handling apparatus comprising an elongate carriage having two trucks which are located respectively at its ends, said trucks having wheels which are arranged to enable the carriage to travel laterally of its length along a pair of spaced-apart tracks on the floor surface. The trucks are constituted as upright structures, having vertically-movable cross-heads which are connected with each other by a pair of heavy cross beams. Power means, carried by the trucks, actuate the cross-heads to raise and lower the same and also the cross beams connected thereto. On the cross beams there are fork structures having tines which extend laterally away from the beams and are adapted to support sheared plate sections as well as other stock material. The fork structures have heavy-duty, anti-friction roller means which engage the beams and enable the fork structures to be readily moved along the latter by moderate manual power when no load is being supported. The fork structures are reinforced, and the anti-friction roller means are strongly constructed to enable these parts to withstand heavy metal loads.
