A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A liquid storage vessel having a base with a bottom and an interior floor; a continuous side extending vertically from the base and having an interior surface, the bottom and continuous side each including an internal layer and an external layer separated by a material barrier, and configured such that the interior layers form an inner containment liner, and the external layers form a continuous exterior structural shell enclosing the inner containment liner. A top is affixed to the continuous side and has an interior ceiling. Access to the tank interior is provided by one or more manways. Mounting and connecting structures enable the tanks to be stacked directly atop one another and then structurally connected. The exterior structural shell is fabricated from high performance fiber reinforced concrete, and the inner containment liner is fabricated from a geopolymer concrete blend.

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.

A charging port 5 in an upper part is covered in an openable and closeable manner with a lid body 6 of a sliding door type (sliding type) that reciprocates horizontally. The lid body 6 reciprocates in conjunction with a movement of an operation member 50 provided in a side part of a container vessel 3 or at a location close to the side part. It is preferable that the charging port 5 includes an opening that is long along a length direction of the container vessel 3, and the lid body 6 reciprocates horizontally in a width direction of the container vessel 3 to open and close the charging port 5.

This disclosure provides a discharge actuation apparatus that is configured to not only fully open and close a sliding gate of a bulk material container, but also move the gate pin to a neutral position with respect to a keeper slot of the bulk container and a receiver slot of the discharge actuation apparatus to ensure proper alignment of the receiver slot and the keeper slot with the gate pin of the bulk container to reduce the likelihood of damage to the receiver or the bulk container during the container's replacement on to the receiver.

A container may comprise a support frame with sides and at least one of the sides being an open side defining an opening, a flexible panel configured to at least partially cover the open side of the support frame, and a panel mounting assembly configured to removably mount the panel over the opening. The panel mounting assembly may comprise at least one panel mounting element including a leverage structure configured to provide a fulcrum edge along at least a portion of the opening, with the at least one portion of the panel being tensionable over the fulcrum edge. The panel mounting element may also comprise a tensioning structure mountable on the leverage structure and configured to selectively apply tension to the at least one portion of the panel with the thicker thickness over the fulcrum edge of the leverage structure.

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.
