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.

Systems and methods relating to the safety of railway cars carrying flammable materials. A rail tank car having an inner tank and an outer protective wall surrounding the inner tank is provided. The outer surface of the inner tank and the inner surface of the outer protective wall are separated by a gap. A low emissivity coating is applied to one or both of the outer surface of the inner tank and the inner surface of the outer protective wall. Existing rail tank cars with a similar construction can be retrofitted by spraying the low emissivity coating inside the gap to thereby coat at least one of the inner surface and the outer surface. Preferably, the low emissivity coating has an emissivity coefficient of, at most, 0.8.

The invention provides a quickly deployable fabric cover over rectangular containers to protect contents from stationary or mobile activities. Operated by a single person to secure or unsecure the cover and to cover or uncover the container minimizes time and energy to protect container contents from inclement weather events or transportation.

An agricultural vehicle includes a chassis, a plurality of ground-engaging elements, and a liquid holding tank. The liquid holding tank includes a first bladder disposed within an interior of the liquid holding tank, the first bladder defining a first chamber within the first bladder, and a second chamber defined between a wall of the liquid holding tank and an outer surface of the first bladder. A method of forming a liquid holding tank of a vehicle includes disposing a first bladder within an interior of the liquid holding tank, a first chamber being defined within the first bladder and a second chamber being defined between an inner wall surface of the liquid holding tank and an exterior of the bladder, and causing both of the first chamber and the second chamber to be in fluid communication with a delivery system of an application system of the vehicle.

A bulk fluid storage container includes a frame assembly having a lower rectangular frame, first and second wheel assemblies extending from opposite ends of the lower rectangular frame, and an upper rectangular frame member arranged in spaced relation to the lower rectangular frame member by a plurality of vertically extending posts. The bulk fluid storage container also includes a fluid storage vessel having first and second end walls held in spaced relation by first and second side walls, a top wall and a bottom wall, which defines a fluid storage volume. A baffle assembly having a plurality of baffle plates is disposed in a space relationship in the fluid storage volume. The frame assembly provides an exoskeletal structure which surrounds the fluid storage vessel and is configured to support a second bulk fluid storage container in a vertically stacked relationship.

The invention relates to a container for transporting a vehicle therein, which is essentially rectangular in construction with a first and a second end face, two long sides, a bottom, and a top, wherein the container has a floor element, a frame structure, and at least two cover elements, wherein the at least two cover elements cover the end faces, the long sides, and the top of the container when in the closed state, and the floor element covers the bottom of the container, and wherein the frame structure builds on the floor element and, in the region of the top, the at least two cover elements are hinged to the frame structure in such a way that they can be swung upward away from the floor element when the container is in an open state.

This disclosure relates to a barrier assembly that can be selectively secured near an opening of a cargo container and selectively deployable near the opening of the cargo container (e.g., along the rear and/or side of the cargo container) to control access to the space therein and to help secure cargo contained within the space. The barrier assembly can include one or two panels that can permit the barrier assembly to wrap, bend, or flexibly extend around cargo. In at least some examples, at least one panel can be hingedly affixed to a side of the cargo container, such that the panel can rotate between a stowed position and a deployed position. In examples, the panel is also slidably connected to the side of the cargo container, such that a fore-aft position of the panel can be adjusted and customized to the cargo.

An eco-friendly detachable container including a base assembly having a metallic plate attached to a support panel; telescopic corner posts; side panels; a top panel; a first door assembly; a second door assembly; a locking mechanism. The detachable container is vertically adjustable. The support pane, the telescopic corner posts, the side panels, the top panel, the first door assembly, the second door assembly, and the locking mechanism are made entirely from recycled plastic, virgin plastic, or regrind plastic. The metallic plate is made of a recycled aluminum.

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.
