  • Patent number: 5887680
    Abstract: Pallet level loading apparatus with a three-sided opened top enclosure and a bottom in which a cantilever-supported lifting platform is vertically movable. The lifting platform is driven by a hydraulic system housed in the rear wall of the enclosure. The platform may be locked in position at a predetermined height within the three-sided enclosure to permit its movement from place to place by a hand pallet or forklift. The apparatus further includes a torsion shaft. The torsion shaft arrangement distributes eccentric loads on the cantilever supported lifting platform so that the platform will not experience lateral tilt. Two vertical guide masts are arranged for receiving a roller arrangement of the lifting platform in order to prevent front and back platform tilt.
