DJ Products' CartCaddy motorized cart is designed to work with equipment and carts that are attached to a steering system and that move in a straight line. While providing directional force, the cart mover steering mechanism maintains the route of the cart. The motorized cart is extremely successful in both assembly lines and other applications, such as moving a cart in and out of a paint booth or an oven.
