A lift tray is slid externally from the vehicle and lowered to the ground for access to the lift tray and raised to the level above the ground floor of the vehicle and slid into the vehicle to its transportation position. The lifting tray apparatus comprises a first pair of opposed slides (3) adapted to be connected to the floor (2) of the vehicle. A pair of swing arms (8), adapted to slide along the first slides (3), each having a free end connected to a second pair of slides (9). The lift tray is adapted to slide along and between the second slides. Each swing arm is in the form of a parallel linkage and has operating means connected across one of its diagonals. When the lifting tray is slid externally of the vehicle, by altering the length of the diagonal, the swing arm moves the lifting tray between a ground engaging position and a position above the floor of the vehicle. In an alternative embodiment, bowden cable pull the tray along the slides.</p> |
