Abstract: An open top debris collection and transport cart with a hitch connector at a first end wall, a pair of wheels at an opposite second end wall, and a bottom panel connecting the end walls. The second end wall is outwardly angled from the bottom panel terminating in a top end, the wheels being positioned adjacent to the ground when the bottom panel is supported on the ground or when the bottom panel is rotated to a vertical orientation and the top end contacts the ground. An elevatable boom connectible to a work vehicle and having a mating hitch connector is provided. Elevating the boom slightly when the hitch is connected supports the cart by the wheels in contact with the ground surface allowing the work vehicle to move the cart. Further boom elevation rotates the bottom panel to a vertical orientation thus dumping the cart contents.

Abstract: A bodyweight stabilizing locomotive device includes a frame configured to support locomotive movement and a stabilizing assembly carried by the frame. The stabilizing assembly has a first spring assembly with a first spring constant, a second spring assembly with a second spring constant different from the first spring constant, and a third spring assembly with a third spring constant different from the first and second spring constants. At least one of the first, second, and third spring assemblies includes lockout means which prevent extension of the one of the first, second, and third spring assemblies beyond a maximum extension.

Abstract: A bodyweight unloading locomotive device includes a frame configured to support locomotive movement, and an unloading assembly carried by the frame. The unloading assembly includes a spring having a fixed end coupled to the frame and an opposed free end, a cam assembly mounted to the frame for rotational movement, a first tether extending from the free end of the spring to the cam assembly, and a second tether extending from the cam assembly to a load. The unloading assembly exerts an unloading force on the load with respect to the frame.

Abstract: A bodyweight unloading locomotive device includes a frame mounted on wheels for locomotive movement. The frame has opposed left and right sides and a harness for supporting a user between the left and right sides. An unloading assembly is carried on each of the left and right sides, wherein the unloading assemblies each includes a sprung arm having a fixed end fixed to the respective left and right side, and an opposed free end. The assemblies further each include a cam assembly mounted on the free end of the sprung arm and a tether routed through the cam assembly and extending to the harness. Each of the unloading assemblies exerts an independent unloading force on the harness with respect to the frame.
