A container door electronic seal system for sensing abnormal opening/closing of a container door comprising a retainer, on which a locking rod installed outside the container door is seated, and a handle hatch, which binds or unbinds a handle seated on the retainer, according to the present disclosure, comprises: an electronic seal, which binds the retainer and the handle hatch, and which wirelessly transmits the abnormal opening/closing information of the container door to the outside; a first connector electrically extending from the electronic seal; a second connector, which is installed on the container door, and which is electrically connected to the first connector; and a first sensing unit electrically connected to the second connector to sense whether the handle hatch is opened/closed. According to the present disclosure, a sensing unit, which senses abnormal opening/closing of the container door, is installed on the container door and is recycled, thereby making it possible to implement an electronic seal system that can sense abnormal opening/closing of the container door with little costs.

A container comprises a container body, wherein a side face of the container body is provided with a container door, wherein the container door is engaged with a corner column on the container body and is fixed to the corner column via a hinge and is connected to a J-shaped strip column arranged on an outer side of the corner column. The corner column is connected to the J-shaped strip column via a corner block arranged on an end portion thereof, wherein the corner block, the corner column and the J-shaped strip column define a long strip-shaped space, the long strip-shaped space being provided with a management module. The management module comprises a radio positioning/communication system.

The double-walled waste container provides an open-top roll-off container being rectangular in shape and having latching door portions at one end. The container employs a double wall construction to minimize damage, improve strength, and reduce weight. Additionally, the container provides a plurality of drain apertures which extend a full length of the container to drain off accumulated liquids and to prevent corrosion of the container.

A construction material transport container includes four side doors that form substantially all of two side walls of the container. The container includes transversely disposed forklift pockets that can be used to load the container onto a flatbed truck. With the container on a truck and the side doors open, new construction materials can be loaded onto the container from both sides. Both the container and the new materials can be delivered to a job side by a single delivery using a truck-attached forklift. The empty container can then be used as a receptacle for recyclable materials. The container further includes roll-off or hook lift vehicle tracks configured so that the container can be picked up and hauled to a recycling or refuse center. A rear door of the container can be opened so that the container can be tilted by the vehicle to offload the used material.

A modular door assembly is provided and includes a storage container and a modular door. The storage container includes a body defining an interior storage space, a door opening positioned at a door end of the body that is communication with the interior storage space, and a pair of container doors each secured to the door end of the body by a container door hinge. The container doors are movable between a container closed position to cover the door opening and a container open position allowing access therein. The modular door is removably attachable to the door end of the body and closes the door opening with the container doors in the open position.

A vacuum system for use in excavation operations. The system uses a tank having an open end that is closed by a door. The door is opened and closed by a door lifting assembly made up of an upper linkage arm, a lower linkage arm and a hydraulic cylinder. A socket is formed in the upper linkage arm, and a shaft housing is formed in the lower linkage arm. The shaft housing engages with the socket to latch the door closed. The upper linkage arm is attached to the door at a first pivot axis and is attached to the lower linkage arm at a second pivot axis. The lower linkage arm is attached to a side of the tank at a third pivot axis. When the door is open, the second pivot axis extends below a reference plane that contains the first and third pivot axis.

Embodiments described herein include layered mesh containers and methods for using the containers to safely transport and dispose of airbag inflators having ammonium-nitrate-based propellant. For example, a container is provided that can hold multiple airbag inflators and withstand up to 4 moles of matter being deployed from an inflator having ammonium-nitrate-based propellant. The container can contain the inflator and any shrapnel associated with the explosion while also venting gases expelled as a result of the explosion. Various container designs are provided, along with methods for using these containers.

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.

A container may have a floor, a ceiling, a first side wall, and a second side wall, a first end wall, and a second end wall. The first side wall, the second side wall, the first end wall, and the second end wall may be formed from a container wall for reducing an effective radar cross section of the container. The first side wall and the second side wall in a longitudinal direction of the container mid-height between the floor and the ceiling may be foldable inward into the interior of the container. The first side wall may include a first cladding board that is permeable to radar rays and reduces the effective radar cross section of the container. The first cladding board may have a reflective agent that reflects radar rays and can be aligned to be at least partially inclined relative to a plane of a main extent of the first cladding board.
