    Abstract: The disclosed warehouse loader has two platform sections. One section is hinged to a deck where the operator stands when moving the loader. The other section is hinged to the first section and can be aligned with the first section to create a platform that extends outwardly from the deck and can be accessed by the operator directly from the deck. The second section is narrower than and folds against the first section. A spring-loaded latch holds the first section in an upright position, with the second section folded against it. A manually-operable positioning hook engages receptacles in the platform sections, making it easier to fold the sections. To retrieve a spilled article, the loader is first positioned at an open location adjacent the spilled article. The platform is extended into the open location. The operator can then stand on the platform while retrieving the article.

  • Patent number: 7699141
    Abstract: The invention is a device mounted on a forklift to provide the operator with information of the distance from the pallet load to the upright part of the fork/tines. The invention has a source of a range determining signal such as sonic waves but other signals such as infra red or radar waves may be used. The emitted signals hit the palletized goods and are reflected to a detector or sensor and processed. The range information is transferred to a distance display device. The range/distance between the upright part of forklift tines and the palletized load combined with knowledge of the length of floor parallel tines of the forks will provide information to prevent any excessive penetration of the pallet hollow which excessive penetration can cause damage to either truck trailer walls, warehouse structures, or other palletized loads.

  • Patent number: 6241453
    Abstract: A satellite vehicle for moving pallet units (P) in and out of storage with transportation vehicles (F) is configured as a motor-driven lift-truck (1) with several parallel, adjacent and height adjustable fork arms (2). The position of said fork arms (2) in relation to the pallet can also be adjusted. At least two fork arms (2) are mounted on the lift-truck (1) in such a way that they can be displaced laterally, crosswise to the longitudinal direction of the arms. All of the fork arms (2) have pallet-receiving elements (3) which float crosswise to the longitudinal direction of the arms. The lift-truck (1) and the fork arms (2) are provided with ultrasound sensors (17, 18) for measuring and correcting the direction of travel and the lift-truck (1) is equipped with a rotation rate sensor (19) for measuring the angle and a cable drum (5) with a power and signal cable (6) for supplying propulsive power and for exchanging signals for measuring displacement.

  • Patent number: 6179541
    Abstract: This transfer device is to be supported by the tines of a forklift and supports a load such as a lumber pack to be transferred to a rack cell which have an anchor bar at its opening. The device comprises an underframe having tine receivers, and a mainframe which is movable with respect to the underframe towards the cell opening and which has hooks to hook onto said anchor bar. Said mainframe has rollers on which the load is supported. The system is motorized; first, the load remains centered with respect to the underframe when the mainframe is first shifted laterally of the forklift to hook onto the anchor upper bar of a selected rack cell because the frame rollers rotate in a direction opposite to the shifting direction; then the mainframe rollers rotate in the opposite direction to transfer the load into the rack cell.

  • Patent number: 5478196
    Abstract: A method for handling conventional stacks of baked goods trays for the baking industry. A platen is moved underneath side-by-side stacks of trays. The platen supports the underside of the stacks of trays and prevents lateral movement of the bottom of the stacks by guiding the platen into channels that exist in the bottom of the trays. The platen is attached to an upright which is tiltable and which extends along one side of the baked goods trays when on the platen to support the stacks along their vertical height. Tilting of the upright causes the platen to lift and the trays to tilt against the upright where they are supported underneath and along the side and thus can be moved and handled. By utilizing the split platen and the tall tiltable upright with a motorized vehicle, an economical and efficient method of handing baked goods tray stacks is possible, eliminating significant manual labor and risk of worker injury.
