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

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.

A bulk material shipping container in one embodiment including a pallet, a bottom compartment mounted on the pallet, a top compartment mounted on the bottom compartment and movable from a retracted position relative to the bottom compartment to an expanded position relative to the bottom compartment, a plurality of top compartment supporting assemblies configured to support the top compartment in the expanded position relative to the bottom compartment, and configured to release the top compartment from the expanded position to enable the top compartment to move downwardly into the retracted position, a material unloading assembly, a material loading assembly, and an extension assembly.

In one embodiment, the present invention provides a collapsible hopper bin having a dispensing portion and a storage portion. The dispensing portion includes first and second opposing side walls and first and second opposing end walls. The storage portion includes first and second opposing side walls and first and second opposing end walls. The storage portion first and second side walls are hingedly attached to the dispensing portion first and second side walls. The storage portion first and second end walls are hingedly attached to the dispensing portion first and second end walls. The collapsible hopper bin has a collapsed position and a filled position. The storage portion first and second end walls and first and second side walls are substantially horizontally flat along the top of the dispensing portion in the collapsed position.

The present disclosure provides a transport case, which includes a case body, the case body being internally provided with a containing space for containing materials; the case body includes a supporting framework and a protective coating, the supporting framework being coated with the protective coating, wherein the supporting framework is made of a metal material, and the protective coating is made of a plastic material. The problem in the art known to inventors of low pressure bearing capacity of the transport case is solved.

An automated gate actuator system is provided for use in selectively opening and closing a gate that dispenses proppant from a proppant container during the course of a hydraulic fracturing operation. A lever arm is pivotally mounted for movement to place a drive gear in contact with a driven gear to open and close the gate. The gate may be remotely or autonomously actuated in this manner utilizing an electronic control triggered by human and/or sensor input.
