A material handling device is provided. The material handling device includes a bottom, a frame, a wall, an a plurality of wheels. The bottom includes an upper surface and a lower surface. The frame includes an upper surface and a lower surface. The wall surrounds the bottom and the frame, and includes an inner surface, an outer surface and an inner shelf attached to a lower portion of the inner surface. The inner surface includes an upper surface attached to a portion of the lower surface of the bottom, and a lower surface attached to a portion of the upper surface of the frame. Each wheel is attached to the lower surface of the frame.

A motorized kayak cart is provided. The cart has a frame for supporting the hull of a kayak, a motor that drives two opposing wheels mounted on the frame, and stabilizing bars that contact a ground surface on which the cart rests and slides along the ground surface in order to maintain the cart in an upright position when the cart is in motion so that the cart does not tip over when in use.

The transport device provides a front wall, rear wall, two side walls, and a bed for storage of transported contents. Handle apertures located within the side walls and rear wall are strategically placed to allow the user to manipulate the transport device. The handle apertures enable users to easily position and manipulate the transport device for transporting items and use as a scoop. Storage recesses are found on the rear wall and side walls on the transport device. The elevated storage recesses allow storage above items transported on the bed of the transport device.

A surface walker for human beings consisting of a chassis holding four articulated, movable limbs for walking. Each limb rests on foot, ski or float. Chassis is topped with cushioned seat whereon user lies prone on chest and belly with access to limbs, which are activated with arms and legs. Chassis height and limb length are adjustable. User regulates walking gait, limb stride and motion frequency of limbs. Walker advances on land and water and diverse landscapes. Design incorporates optional computer-controlled power assistance for walker motion and use of mechanical hand for enhanced traction and anchoring effects.

A hand-powered vehicle is provided for transportation and entertainment purposes. The vehicle has a frame supporting a pair of side wheels that are driven by the user. The frame includes a front portion and a pair of side portions extending rearwardly to the side wheels. The side portions of the frame do not extend rearwardly past the side wheels. The user sits on a seat that is supported by a portion of the frame extending rearwardly from the front portion and between the two side wheels. A third wheel is provided under or behind the seat, and that wheel is preferably a caster that is coupled to the frame at an angle to a vertical axis. The side wheels have hand grips extending therefrom, and the hand-powered vehicle is configured to be propelled by a user applying a force through the hand grips to rotate the side wheels.

A vessel for transporting cargo has a first hull and a second hull that are slidably coupled together to be movable between an extended position and a retracted position that is shorter in length. Wheels are coupled to the vessel. The wheels can contact an underlying surface of the vessel when the vessel is oriented at an acute angle relative to the underlying surface. The wheels are free of contact with the underlying surface when the vessel is parallel or substantially parallel to the underlying surface.
