The present disclosure relates to a foldable container which includes a pair of side walls disposed side-by-side; a guide rail disposed in a direction transverse-crossing between lower ends of the one pair of side walls to guide movement of at least one of the side walls; an upper plate and a lower plate, wherein each of the upper plate and the lower plate is divided into at least two unit plates that are rotatably connected to each other so as to be folded by the movement of the side wall, and wherein each of the upper plate and the lower plate connects upper ends of the pair of side walls to each other and connects lower ends of the one pair of side walls to each other; and a door rotatably connected to each of a front end and a rear end of the side wall.

Systems, methods and apparatuses for inspecting a tank containing a flammable fluid are provided. The system includes a vehicle having a propeller, a latch mechanism, a pressure switch, and an inspection device. The system includes a control unit in communication with the propeller, the latch mechanism, and the inspection device, and electrically connected to the pressure switch. The control unit powers on responsive to the pressure switch detecting an ambient pressure greater than a minimum threshold. The control unit receives, from the latch mechanism, an indication of a state of the latch mechanism. The control unit determines that the cable used to lower the vehicle into the tank containing the flammable fluid is detached from the vehicle. The control unit commands the propeller to move the vehicle through the flammable fluid. The control unit determines a quality metric of a portion of the tank.

A container energy storage system is provided in this disclosure. The system includes a container and a plurality of functional assemblies. The container includes a container frame and a bottom plate. The container frame is formed a plurality of openings and a hollow main body. The bottom plate is disposed at the bottom of the container frame and is fixedly connected to the container frame. The functional assemblies are disposed in the hollow main body and located above the bottom plate.

An apparatus, system and method for securing wheeled shipping carts within a shipping container. The apparatus, system and method for securing wheeled shipping carts within a shipping container secures the shipping racks across the width of the container and vertically, and then end-to-end inside the length of the container from the fixed end of the container to the doors as the container is loaded. In addition, the system and method secures wheeled shipping carts within a shipping container using a securing apparatus installed within the shipping container to constrain the wheeled shipping carts both vertically and horizontally in location during transport.

Embodiments of a large container may include a container base and a circumferential container wall. An upper end of the wall is closed by a container cover in the form of a metal disc. An annular, circumferential support element is secured at an upper end region of the wall. The disc spans the upper open end of the container wall. A lower side of the disc is welded to the support element and/or to the upper end region of the container wall by a continuous first welding seam. An upper side and/or an edge of the disc is welded to the support element by a continuous second welding seam. The first and second weld seams have respective first and second roots which merge into one another or at least come together.

A functional training rig kit includes a box and a plurality of components adapted to fit within the box. At least some of the components and the box include elements by which the components are adapted to be attached to the outside of the box to provide at least one functional training rig attached to the outside of the box.

A lightweight barrier insert door is attached to an enclosure, such as a shipping container that holds a product to be fumigated, such as during transport of the product to a new location. The barrier insert door fits within the doorway of the container to provide a sealed barrier to mitigate leakage of a fumigant from the interior of the container. The barrier also includes air intake ports to maintain the structural integrity of the container and to provide ambient air to the interior. Additional ports allow for connection for fumigant entry, monitoring, and/or an exhaust hose to be connected to or through the barrier for the fumigation process. The barrier can be height adjustable to account for shipping containers of various sizes and can be connected with fumigant exhaust and release systems for the safe release thereof.

A method for joining shipping containers together to create a modular structure includes providing a first shipping container and a second shipping container; removing a wall of the side of the first shipper container to create a first opening; removing a wall of the side of the second shipping container to create a second opening; positioning the first opening adjacent and opposite to the second opening; aligning the first opening with the second opening; after the aligning, securing the first shipping container to the second shipping container to create the modular structure; and securing an inner flashing around an inner periphery of the first opening.

A container assembly comprises a container and a base and is configured to be transported horizontally to a work site where it is raised to a vertical working orientation. A hoppered container floor directs material to a discharge opening in a center of the floor of the container. A plurality of chutes is fixed to the container assembly and each slopes downward and outward from a chute input, located under a central portion of the hoppered floor, to a corresponding chute output. A distributor assembly mounted under the discharge opening receives granular material from the discharge opening and directs same into any one of the chute inputs. When loaded on a gooseneck trailer the container extends over the hitch assembly providing increased volume and capacity.

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.
