  • Patent number: 9028195
    Abstract: An apparatus for loading and unloading a truck with cargo includes a mounting frame for attaching adjacent to a truck doorway. The mounting frame includes a first guide member forming a first channel, a first support member slideably received within the first channel, a second guide member forming a second channel, and a second support member slideably received within the second channel. A platform for supporting the cargo is pivotally coupled to the first support member and to the second support member. A power driven lift elevator slides the first support member within the first channel and slides the second support member within the second channel to thereby raise and lower the platform. A power driven platform elevator pivots the platform respect to the first and second support members to move the platform between horizontal and vertical positions.
