A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A logistics apparatus for transporting frac sand, frac liquid, and/or drill cuttings between a terminal and a well pad. The apparatus includes a container having a top and bottom. The top having one or more inlet port for receiving frac sand and a liquid outlet. The inlet orts can be secured by watertight covers. The bottom of the container is configured as a hopper having an opening secured by a railcar gate. The apparatus, in position having the railcar gate at bottom, can be used to store and transport frac sand. The apparatus can be inverted for transporting the frac liquid.

A manway gate assembly couples to a tank and provides a liquid tight seal. The manway gate assembly includes a gate selectively slideable in a first linear direction between an open position, a closed position, and/or an intermediate position between the open position and the closed position. The manway gate assembly includes one or more locking members arranged adjacent to the gate and moveable between a locked position and an un-locked position. When in the locked position, the one or more locking members apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction to seal the gate to the tank and provide a liquid tight seal.

The present invention relates to a container for holding bulk material, having a closable inlet for the bulk material in the upper closure of the container, a cross-sectional geometry narrowing in the outlet direction for the bulk material, an outlet tube for the bulk material arranged subsequently in the outlet direction, a first reversible mechanical closure device (A), which is arranged in the transition region from the container body to the outlet tube or in the outlet tube itself and, by opening, releases the bulk material from the interior of the container, and a second closure device (B) which reversibly closes the mouth of the outlet tube, the second closure device being a cover which is pressed flush onto the mouth of the outlet tube by means of a closure device, there being a seal which seals the outlet tube in a gas- and liquid-tight fashion from the external environment at least on the contact surface of the cover with the mouth degree of the outlet tube, wherein the cover is screwed onto or is pressed with a clamping ring or a bayonet closure onto the mouth of the outlet tube.

A bulk material shipping container unloader having an expandable supporter, a pallet receiver supported by the extendable supporter, a material director supported by the pallet receiver, and a bulk material container gate mover supported by the pallet receiver.

In accordance with presently disclosed embodiments, systems and methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

A system for covering fluid containment tanks to contain vapors and minimize evaporation of the vapors into the surrounding atmosphere. The system includes a flexible cover and restraint elements, guiding rails which support the cover over a tank and provide guidance for extending and retracting the flexible cover, a belt drive extends the leading end of the flexible cover and a drivable drum provides a way to retract the flexible cover and upon which the flexible cover will be rolled and stored, and a method to locate tank elements beneath the flexible cover system to prevent operating interferences.

Method of handling proppant at a well site using a plurality of modular proppant containers in which first and second modular proppant container in a filled state are removed from delivery transport vehicles and transferred to first and second cradle positions on a support structure using one or more heavy-duty handlers. Proppant is discharged by gravity feed from the outlet of the first and second modular proppant containers and directed to a hopper until the modular proppant containers are in an empty state.

The present invention is directed to a cover assemblies for use with containers such as large dumpsters or roll-off containers. The cover assembly generally includes a cover portion, a frame portion, and one or more mounting arms. The cover is coupled to the frame, and the frame is movable with respect to the mounting arm from a first position to a second position, wherein the first position comprises a closed position and wherein the second position comprises an open position.
