ABSTRACT:
A lift arrangement is mounted adjacent the doorway of a vehicle. The arrangement includes a first electrically powered screw jack mounted to the frame of the vehicle adjacent one side of the doorway and a second electrically powered screw jack mounted to the frame of the vehicle adjacent the other side of the doorway. A first support bracket is positioned adjacent the lower end of the first jack. A second support bracket is positioned adjacent the lower end of the second jack. A platform has a pair of connecting portions disposed adjacent opposite ends of the platform. Each connecting portion engages one of the brackets to support the platform in a generally horizontal manner. The first and second jacks are simultaneously activated by a single switch to lower and raise the platform between a position adjacent the ground surface and an elevated position.
