  • Patent number: 4778327
    Abstract: A truck-mounted lifting mechanism is provided for loading containers, such as waste bins, on a truck so that the container can be positioned where its weight will be reasonably distributed between the front and rear wheels. The lifting mechanism includes a track extending along the length of the truck bed, a tray which can be moved along the length of the track while being restrained by the track from any vertical displacement, and a jack-up assembly attached to and supported by the movable tray. A pair of hydraulic cylinders attached between the tray and the jack-up assembly permit the controlled forward tilting of the jack-up assembly toward the truck cab. In use, the jack-up assembly is utilized to securely grasp the container to be loaded, and lift it vertically until the container bottom is above the upper surface of the truck bed. In this elevated position, the tray can be pulled by another hydraulic ram toward the truck cab to position the container over the truck bed.
