  • Patent number: 5172804
    Abstract: A bridge device spanning the distance between a set-up station and a machining center for transporting pallets between the two locations. The bridge is pivotedly coupled to the set-up station allowing the bridge to rotate between a horizontal operating position and vertical storage position. Placement of the bridge in a horizontal position allows pallets to slide across the bridge over rollers incorporated into guide tracks which form a part of the bridge. When the bridge is not in use the bridge is stored in a vertical position by lifting one end of the bridge. A hydraulic dampener allows ease of bridge movement between the operating and stored position. A collapsible support stand supports the bridge in the operating position and folds flush with the main frame of the bridge when placed into the storage position.
