  • Patent number: 5577568
    Abstract: A self-propelled handtruck including a frame and having at least one driven wheel and at least one non-driven wheel such that the handtruck may be selectively positioned in either a self-propelled position or an operator-propelled position. The frame includes a vertical frame member. A drivetrain mounting structure is secured to the vertical frame member. The drivetrain mounting structure preferably provides for selective positioning of the same along the vertical frame member so that the center of gravity of the handtruck may be varied as desired. A drivetrain is secured to the drivetrain mounting structure, the drivetrain being operable to drive the driven wheel. Preferably, the driven wheel is mounted on the frame of the handtruck by at least one wheel mounting plate. The wheel mounting plate includes one end which is fixedly secured to the vertical frame member. Moreover, the wheel mounting plate may be mounted for selective positioning of the wheel mounting plate along the vertical frame member.
