A proppant storage vessel has a container having a first end wall, a second end wall, a first side wall, a second side wall, a top wall and a bottom wall. The first and second end walls extend between opposite ends of the first and second side walls. The walls define an interior volume of the container. The walls have a rigidity suitable for retaining no less than 30,000 pounds of proppant therein. A top hatch is formed centrally on the top wall and is movable between an open position and a closed position. A bottom hatch is formed generally centrally on the bottom wall of the container and is movable between an open position and a closed position.

A storage container for bulk materials includes a rectangular bin containing a an open-ended chamber having a horizontal bottom wall, a pair of vertical side walls and a vertical rear wall, and a pair of parallel spaced centrally-arranged horizontal guide rails that extend longitudinally below the bin, which guide rails have forward end portions that extend outwardly beyond the bin front end. A ramp wall is pivotally connected with the forward end of the bin for displacement between a vertical first position closing the forward end of the chamber, and a downwardly inclined ramp position. A piston and cylinder motor arrangement is connected between the guide rail ends and the ramp wall for displacing the ramp wall between its vertical first and downwardly inclined second positions. The chamber side walls are spaced so that a front end loader can travel up the downwardly inclined ramp and into the chamber.

An innovative vessel 100 which is an all in one smart solution for vehicle storage, display, and transport. The vessel 100 maximizes vehicle loading and unloading access, with a fully automated sliding door system, allowing even large SUVs to be loaded, and all doors on all sides remain accessible. The innovative vessel is stackable, transportable by rail, ship, and truck, and can be used as temporary portable structures, or long term permanent ones.

A stand-alone, all-in-one refrigerator box and, more particularly, to a refrigerator box that provides a built-in ramp that is moveable between a stowaway position and an angled position in connection with the refrigerator box for loading and unloading the refrigerator box without having to disengage the ramp while the refrigerator door is being opened and closed.

A container for storing and transporting materials includes a container body having a generally rectangular configuration with bottom and side walls and a front and rear end defining an inner chamber. A generally rectangular ramp wall is pivotably connected with the container body adjacent the front end. The ramp wall pivots about at least one of a horizontal and vertical axis to provide pivotal movement of the ramp wall between closed and open positions, respectively. The ramp wall further has a height that is less than, equal to or greater than a height of at least one of the side walls and a width which is generally equal to a width of the container body. Preferably, the container further comprises at least one front end door that is pivotably connected with the container body to provide access to the inner chamber via the front end.

An expandable storage container comprises a floor and two longitudinal walls, each wall comprising at least one arm, with the wall connected through the arms to the floor so as to provide lateral extension of the longitudinal walls away from the floor. In certain embodiments, the arms are slideably or hingedly connected to the floor to provide lateral extension.

A modular particulate storage system includes a plurality of portable skids, wherein each skid includes an elongate rectangular base supporting a floor section and a wall section extending upward from the floor section. The plurality of portable skids are securable together in a side-by-side configuration to form a storage bay having a contiguous rectangular floor that combines the floor sections of the plurality of portable skids and a contiguous wall that combines the walls sections of the plurality of portion skids and extends along three sides of the contiguous rectangular floor. One side of the contiguous rectangular floor includes an open passageway into the storage bay. A skid may be formed as a trailer that may be lowered to be supported by the ground.

A crate assembly includes a crate having a base and an interchangeable cartridge supported by the base. The interchangeable cartridge is insertable and removable from the base of the crate. The interchangeable cartridge includes a cartridge base and a well. The well is formed by a floater base, side rails, a back board, and a front board. Energy damping components are selected to support a desired load and are disposed between the cartridge base and the floater base thereby providing cushioning to a load carried in the crate. Brace brackets attach to ends of the side rails. After loading a server rack, openings on the front board slide over end bolts of the brace brackets thereby providing toolless securement of the load within the well. Worn cartridges are replaced with new cartridges thereby extending crate life and cartridges are customizable depending on application to support different load dimensions or weights.
