A fuel trailer configured to store and process fuel. The fuel trailer includes a frame with wheels; a fuel tank mounted to the frame, and a fuel system downstream from the fuel tank to move the fuel from the fuel tank. The fuel system can include filters that remove contaminants from the fuel, pumps to move the fuel, and redundant fuel lines. A dispensing end can be positioned to dispense the fuel to an outside device.

This invention is a specially designed and shaped liquid storage tank that attaches directly to the lift arms of the skid steer or track loader. The storage tank holds a portion of the weight of the liquid in the storage tank directly over the tank treads or caterpillar tracks of the skid steer thereby greatly improving the stability of the skid steer to allow successful navigation of very rugged terrain even with a full load of liquid in the storage tank. At least thirty percent of the storage capacity of the storage tank is positioned behind the attachment plate or quick attachment plate of the skid steer or track loader. The invention may include a hydraulic water pump which can be used to spray water from the storage tank to fight wildfires. The invention may include a hydraulic power generator. The invention may include a fuel pump.

A transportation trailer can include a cargo tank with a shell that includes an outer wall, an inner wall, and an insulating core between the outer wall and the inner wall. The shell can be unsupported by structural rings, and the cargo tank can be a frameless cargo tank. The cargo tank can be formed by decoiling respective coils of inner-wall material, outer-wall material, and insulating-core material, joining the inner-wall material, the insulating-core material, and the outer-wall material to form a sandwich-type panel, and welding the sandwich-type panel to form the shell.

A vehicle with a carpet cleaning system comprises a plurality of operational units mounted within the vehicle, including a blower pump unit, a vacuum recovery tank unit, a reel and tank unit, and an auxiliary tank unit. The operational units are mounted on a stainless steel mounting frame that defines zones for mounting each of the operational units. The mounting frame having attachment points that align each of the respective operational units which facilitates the initial assembly of the unit. The mounting frame is secured to the floor through a minimal number of opening extending through the floor. The operational units are secured with a multiplicity of threaded connectors to the frame. The separation of the individual operational units from direct attachment to the floor dramatically reduces corrosion of the vehicle and equipment, facilitates the initial assembly and minimizes maintenance and repairs.

A mobile cart includes a frame; a front pair of wheels and a rear pair of wheels. At least one carrier is movably attached to the frame and configured to receive a drum thereon. The carrier is movable between a transport position, wherein the carrier is supported upon the frame, and a loading position, wherein the carrier is oriented generally upright. A corresponding at least one motorized drive member is attached to the frame and to the carrier, the motorized drive member being configured, when actuated, to move the corresponding carrier between the transport position and the loading position.

The present invention is directed to a rigid cover for a dump trailer tank having a storage region with an open top used to transport bulk material. The rigid cover includes cover side walls having a top wall perimeter and a bottom wall perimeter and is configured along the bottom wall perimeter to correspond in shape with the open top of the trailer tank. The rigid cover includes a cover top connected to the cover side walls along the top wall perimeter and includes one or more ports in the top. The rigid cover includes cover fasteners mounted along the bottom wall perimeter configured to secure the plurality of cover side walls to the trailer tank so the traditional storage region of the trailer tank is transformed into an expanded storage region that allows storage of more bulk material than could otherwise be stored in the trailer tank alone.

The present invention relates to a self-propelled vessel assembly (3) that includes a self-propelled vehicle (11) that includes an open-box bed (14). The self-propelled vessel assembly (3) further includes, a vessel (50) that is reversibly received (and reversibly resides) within the open-box bed (14) of the self-propelled vehicle (11). The self-propelled vessel assembly (3) additionally includes, a pump assembly (59) that includes at least one pump (62) and at least one conduit (e.g., 71) that is in fluid communication with the interior volume (56) of the vessel (50). The pump assembly (59) resides on a support structure (47) that is reversibly attached to the self-propelled vehicle (11).

A structurally supportive belly pad is connected to a rounded trailer and configured to support the same near the rear end of the trailer. The belly pad may be arcuately curved complementary to the curvature of the rounded trailer. However, if the belly pad were laid flat, it includes a pair of parallel legs aligned in a generally longitudinal direction with a plurality of transverse ribs extending therebetween. The shape of the belly pad is configured to provide structural support for the trailer which is beneficial especially when the trailer is raised and lowered, typically through hydraulic mechanisms.
