A low profile holding tank-evacuable to a pressure differential of at least about 10 of mercury that includes a plurality of support structures, a peripheral wall, an upper outer layer of mild steel and a lower outer layer of mild steel, each of the upper outer layer and the lower outer layer is configured to be up to about inches thick. At least some of the plurality of support structures are required to be fixedly connected to upper and lower outer layers to prevent damages incurred on the low profile holding tank by repeated applications of the pressure differential of at least about 10 of mercury. At least some of the connections are required to be made from the outside of the tank via a welding, e.g., plug welding, technique.

A storage tank assembly for a work vehicle includes a frame assembly configured to couple to a structure of the work vehicle. The storage tank assembly also includes a storage tank configured to store a liquid. The frame assembly is configured to support the storage tank on the structure of the work vehicle. In addition, the frame assembly is configured to position a first portion of the storage tank above a wheel assembly of the work vehicle, the first portion of the storage tank is contoured to substantially match a curvature of the wheel assembly, and the frame assembly is configured to position a second portion of the storage tank laterally inward of the wheel assembly such that the second portion of the storage tank extends within a vertical extent of the wheel assembly.

A device for restricting liquid backflow through an overhead line on a tank and a method of using the device are provided. The device has a tubular housing with spaced internal baffle plates. The device is secured in place in the interior of an overhead pipe on the top of a tank on a tank truck or other vehicle used for transporting bulk liquid cargo. The device prevents liquid backflow from entering overhead piping due to sloshing action of the liquid during transport. The device allows air to flow through the device so that air may be supplied to the tank, as well as vented from the tank, through the device.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A temporary addition or injection system installed without the need for civil work comprising: one or more silos mounted on a trailer; optionally one or more transfer pots; and one or more control systems, wherein the one or more transfer pots and the one or more control systems are either (a) directly or indirectly connected to the one or more silos mounted on the trailer or (b) mounted adjacent to the one or more silos mounted on the trailer.

An example fluid storage system for a mobile waterjet system comprises a first tank having a first side and a second side opposite the first side. A second tank abuts the first side, and a third tank abuts the second side.

The present invention comprises a multi-featured trailer designed with transporting hazardous material in mind. The trailer design allows a driver without a hazardous materials transport license or commercial driver's license to legally transport the trailer when it contains hazardous material. It includes a unique hand-rail and bracket system designed to allow the trailer to employ standard sized rails which provides structural support and economic advantage. Further, the inventive trailer features means to accommodate several different tanks together or alone, comprising different capacities and sloped bottoms, in addition to tools and/or machines while employing the same frame, axles and wheels. Employing the inventive design further allows each tank trailer to be assembled to order providing a significant manufacturing advantage.

A mobile vessel for refueling an engine or tank of a vehicle at a remote refueling site. A refueling station is mounted to the mobile vessel and includes a movable platform mounted to a generally horizontal deck. The platform is movable between a deployed position and a stowed position. In the deployed position the platform extends away from the deck to provide a floor for the worker to stand on to connect the fuel dispenser to the engine or tank. In the stowed position the movable platform is folded from the deployed position towards the generally horizontal deck.

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.

A system for fastening a tension rod of a grain tank of an agricultural vehicle to a frame of the agricultural vehicle to which the grain tank is mounted. The tension rod includes an elongated body extending between a first connection end that is configured to be connected either directly or indirectly to the grain tank, and a second connection end including openings for respectively receiving fasteners. A first member is either configured to be mounted to the frame or associated with the frame. The first member includes (i) openings for respectively receiving the fasteners, and (ii) a first non-planar mounting surface. A second member includes (i) openings for respectively receiving the fasteners and (ii) a second non-planar mounting surface that is configured to be directly engaged with the first non-planar mounting surface to limit relative motion between the tension rod and the frame in an assembled state.
