A storage vessel includes a body, two or more internal chambers or sections which may hold fluids or debris, one or more bulkheads 108 within the body of the storage vessel to separate the sections, and a roll off attachment apparatus. The storage vessel also comprises a series of ports and hatches to provide access to the sections within the storage vessel. The storage vessel can be moved to and from excavation sites using the roll off attachment apparatus which allows the storage vessel to be attached to or lifted onto a truck.

A storage silo for storing granular material has a container supported by a base, the container having a roof and at least one side wall for defining a storage space beneath the roof. The storage silo includes: (a) a feed port for receiving the granular material at a feed-port height lower than the roof; (b) an auger for moving the granular material toward the roof within the storage space, the auger receiving the granular material via the feed port; and (c) first and second auger motors for cooperatively driving the auger, the first and second auger motors being disposed at opposing ends of the auger. A processor determines power levels for the first and second auger motors to minimize torsional strain on the auger. Granular material can be discharged from a first storage silo into a second storage silo positioned for cascading with the first storage silo.

A collapsible storage silo having an expanded configuration includes: (a) a shell for circumscribing storage space and comprising a plurality of concentrically nested tubular members that are collapsible; (b) a lift system operable to slidably expand the plurality of concentrically nested tubular members to place the silo in its expanded configuration; and (c) a mast operable to support the lift system, The mast is pivotable between horizontal and vertical positions relative to a frame. A winch attaches to the mast and a cable extends between the winch and an outermost tubular member to expand the silo such that inwardly and outwardly projecting lips of nested members engage each other and a conical hopper engages an innermost tubular member. A flexible inner liner attaches between an outermost tubular member and the hopper. A collapsible roof has a flexible roof membrane and a plurality of radially extending foldable rib members.

A sulfur storage tank includes a bottom plate, an outer wall, and a cleanout door. The outer wall surrounds and is coupled to the bottom plate. The cleanout door is installed on the outer wall. The cleanout door includes an edge and a drain nozzle. The edge abuts the bottom plate. The drain nozzle is installed on the cleanout door. The drain nozzle defines a centerline offset from the edge. The drain nozzle is configured to gravity drain fluid from the sulfur storage tank.

An article reversing/discharging box 1 includes a box main body 2 that accommodates scrap, hook members 3, 4 having insertion holes 3a, 4a through which forks of a forklift are inserted above the box main body 2, and a reversing mechanism 5 capable of reversing the box main body 2. The reversing mechanism 5 includes a bottom plate 6 integrally extending from a lower end of the movable hook member 4 along the bottom surface 2d, and a hinge 7 provided at a distal end portion of the bottom plate 6. When the forks are inserted into the insertion holes 4a of the movable hook member 4 and the forks are removed from the insertion holes 3a of the fixed hook members 3, the box main body 2 is turnable about the distal end portion of the bottom plate 6 by the hinge 7.

A tank container includes a frame having a front end opposite a rear end that defines a rear plane, a vessel extending between the front end and the rear end of the frame, and a discharge valve assembly. The discharge valve assembly comprises an internal bottom valve, an adaptor, and a discharge valve. The internal bottom valve is positioned within an interior volume of the vessel and the discharge valve is positioned entirely within the frame and offset at least one inch from the rear plane. The adaptor curves downwardly between the internal bottom valve and the discharge valve.

The disclosure provides a bulk material container including a body and one or more first engagement elements. The body includes a plurality of side walls, a bottom, a cavity, and an opening. The plurality of side walls are coupled to the bottom, and the cavity, which is configured to receive a bulk material, is formed within the plurality of side walls and above the bottom. The opening is formed by the plurality of side walls spatially opposite of the bottom and is configured to discharge the bulk material when the bulk material container is at least partially inverted. The one or more first engagement elements are coupled to the bottom of the body, and the one or more first engagement elements are configured to receive one or more prongs of a transportation device or a bulk material unloading device.

A flexible tank fillable with a liquid having a base and at least one enclosing wall. The base has an upper surface and a lower surface, and defines a plurality of edges and a perimeter. The enclosing wall extends about the base and is attached thereto to, together with the base, define an enclosure. The inner brace assembly comprises at least one inner support member having a base wall attachment side and an encasing wall attachment side. The base wall attachment side is attached to the base spaced apart from the perimeter. The encasing wall attachment side is attached to the at least one enclosing wall spaced apart from the base fold.
