ABSTRACT:
Freight handling apparatus for unloading stacks of beverage containers supported on pallets within bay wells of a beverage delivery truck having floors tilted inwardly and downwardly toward the center of the truck includes a wheeled frame having an upstanding mast on which a vertically movable carriage is supported mounting a pair of forwardly projecting lifting forks engageable with the pallet load. A hydraulic lifting jack is operable for raising and lowering the forks. A hydraulic tilting jack acts between a set of rear wheels and the back of the frame for selectively elevating the back of the frame relative to the front so as to angle the fork tines downwardly from horizontal to correspond in inclination to that of the floor of the bay wells. The downward angling of the fork tines enables them to be inserted into the correspondingly angled pallet load, and the forks thereafter elevated to lift the pallet load for subsequent removal from the bay well. The apparatus also has a self-stowing feature wherein the fork tines are insertable into suitable hangers mounted to the undercarriage of the truck and the lifting cylinder being double acting for lifting the frame into engagement with the truck undercarriage for transport by the truck when not in use.
