The invention relates to a locking system for locking of a room that is provided with at least one and preferably two doors or openings, said locking system comprising a lock holder with a lock and two toothed wheels with teeth for insertion of a locking boom behind the door, and an arresting device that is connected to the lock for arresting the wheels in locked position. Furthermore, the invention relates to the use of the locking system for locking of for instance shipping containers.

Shipping system for temperature-sensitive materials. In one embodiment, the shipping system may include a frame defining an enclosure. The frame may include a bottom, a top, a front, a rear, a left side, a right side, a left corner gusset, and a right corner gusset. The front may serve as a door. Thermal breaks may be provided in one or more of the bottom, the front, the left corner gusset, and the right corner gusset. Vacuum insulated panels may be positioned along all sides of the frame. Many of the vacuum insulated panels may be encapsulated between the frame and an outer shell. A plurality of phase-change material assemblies may be positioned within the frame along all sides. Heat-spreaders may be positioned interior to the phase-change material assemblies. The shipping system may be dimensioned so that four such shipping systems may be seated on a prorate manual cargo sheet.

A latch for securing a component to a track in a base of air cargo equipment, such as a pallet or the floor of a unit load device. The latch includes a rigid support configured to be attached at the bottom edge of the component. The latch also includes a handle. The handle rotates relative to the support between an open position and a closed position. The handle uses a rotationally tapered locking cam to secure the component to the track. In one embodiment, the component is a door, such as a fabric curtain.

A safety door latch system is presented for a grain bin having a door frame. An inner door is connected to the door frame that is configured to move between an open position and a closed position. An outer door is connected to the door frame and is configured to move between an open position and a closed position. A safety mechanism is connected to the door frame and is configured to move between an open position and a closed position. When the inner door frame is moved to a closed position, a portion of the inner door engages the safety mechanism thereby causing the safety mechanism to move to the closed position. When the safety mechanism is in the closed position, the outer door may be latched to the safety mechanism. When the safety mechanism is in the open position, the outer door cannot latch to the safety mechanism.

The present disclosure provides a hinge, a freight container that includes the hinge and a freight container that includes a locking rod and optionally the hinge. The hinge includes a locking pin, a first wing, a second wing and a first hinge pin that pivotally connects the first wing to the second wing. The hinge further includes a pair of hinge lugs each having a first set of surfaces defining openings through which a second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which a locking pin reversibly travels. The locking rod is mounted to the door of the freight container, where the locking rod includes a cam that can move between a first predetermined position where the cam can engage the cam keeper and a second predetermined position where the cam is disengaged from the cam keeper and can travel past the end frame of the freight container and the cam keeper as the door travels into the volume of the freight container.

A cargo container includes a base, side walls and a rear wall on the base and a top attached to the side walls and the rear wall. A front frame is attached to the base, the side walls and the top. Left and right swing out doors are pivotally attached to the left and right sides of the front frame. A roll up door is attached to a top of the front frame, in between the left and right swing out doors. The container may be loaded and unloaded with the swing out doors and the roll up door open, providing a maximum size front opening, or with the swing out doors closed and the roll up door open, providing a reduced size front opening equal to the width of the roll up door.

A method is disclosed for storing and moving proppant. A supply of fracking proppant is provided at a remote location. A plurality of containers are provided to the desired location, each container having a top, a plurality of walls extending from the top and terminating at an outlet for discharge of proppant therefrom and a flow gate positioned adjacent the outlet to control flow of proppant from an interior volume of the container through the outlet. The plurality of containers are filled with fracking proppant at the remote location, then transported from the remote location to a well site location. The plurality of containers are staged at the well site location and the amount of proppant on hand at the well site location is tracked.

A lightweight shipping container includes two parallel side walls each having a top rail and secured on the opposite side to bottom rails of a floor frame, both bottom rails being coupled to one another by a floor, which is secured to and resting on a multiplicity of cross-beam members of the floor frame. A front end assembly is secured to one end of the top and bottom side rails and a door end assembly opposite the front end assembly is secured to an opposite end of the top and bottom side rails. The container further includes a roof secured to respective ones of the top rails of each of the two side walls. The floor includes a metallic cellular sandwich panel formed by a frame defining an interior portion of the panel and including a metallic cellular core of a multiplicity of metallic polygonal cells, and a skin covering both the frame and the metallic cellular core.

Certain aspects of the present disclosure provide a container, including: a floor; a plurality of vertical walls coupled to the floor; a ceiling coupled to the plurality of vertical walls; a first horizontal gate coupled to a first vertical wall of the plurality of vertical walls and comprising a first plurality of foldable portions; a second horizontal gate coupled to a second vertical wall of the plurality of vertical walls and comprising a second plurality of foldable portions; a third horizontal gate coupled to a third vertical wall of the plurality of vertical walls and comprising a third plurality of foldable portions; and a first vertical gate coupled to the ceiling and comprising a fourth plurality of foldable portions, wherein, when extended, the first horizontal gate, the second horizontal gate, the third horizontal gate, and the first vertical gate form a plurality of separate cargo volumes.

A cargo securement system for securing cargo in a container includes a number of upper and lower braces. The upper braces abut a ceiling of the container and the lower braces abut a floor of the container. The lower braces have a module engagement rail sized to slide within a rail guide of a module to guide the module to stowed position within the container and prevent movement of the module along a horizontal and a vertical axis. Bracing rods provide a compressive force to the upper and lower braces to provide a pressure fit that secures the braces and corresponding modules in place.
