ABSTRACT:
A compact powered manlift cart suitable for usage in building interiors for raising and supporting an operator at elevated heights. The cart has front and rear wheels of which one front and one rear wheel are driven by a two-speed drive motor through a chain and sprocket drive train. Power driven front and rear steering assemblies allow the front and rear wheels to be steered independently of one another making the cart highly maneuverable. A lift mast for raising and supporting the operator includes a lift bucket wherein the operator stands during operation of the cart and also includes telescoping mast sections driven by a motor through a cable and pulley arrangement. The mast is extended and retracted for positioning the lift bucket at various heights up to a maximum height for supporting the operator for overhead work. A hand operated control box with a single control rod allows the operator to selectively control the speed and movement of the cart and movement of the mast while standing in the lift bucket or while separated from the cart.
