ABSTRACT:
Each of the tines of a fork lift truck is provided with a sleeve which is telescopically slidable thereover. A cross member joins the sleeves at their inner ends closest to the truck. A mechanical linkage is mounted on the truck and attached to the cross member. Extension of the linkage causes the covering sleeves to be tine extensions thus permitting a load carried thereon to be forwardly extended relative to the lift truck. A bail member having a rectangular perimeter is pivotally mounted at its rear on the lift truck to the rear of the tines and is positionable either in a substantially vertical position adjacent the front of the lift truck or in a horizontal position where the front cross member rests on the top surface of the sleeves. A cross slatted pallet carrying a load is positioned across the forwardly extending tines with their sleeve covers. Each of the sleeves is provided with a fixed lug on its top side. The lugs, transversely aligned, are adapted to engage one of the pallet cross slats and thus fix the pallet with respect to the tines and their sleeve covers. The forward end or cross member of the bail in its horizontal position acts in effect as a pusher of the load to thereupon strip the load of the pallet from the pallet when the extended sleeves are retracted.
