A foldable shipping container adjustable between an unfolded condition in which said container is suitable for use as a cargo container, and a folded condition for when said container is not being used to store or ship cargo. The foldable shipping container having ways for controlling the rate at which the panels collapse.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

An apparatus for sealing a vacuum tank door. The apparatus comprises a circular flange attached to a door panel of a vacuum tank, a horizontal crossbar connected to the center of the door panel and a lifting assembly. The lifting assembly comprises an upper linkage arm, a lower linkage arm, and a hydraulic cylinder. Activation of the hydraulic cylinder causes the linkage assembly to move downwards pulling on the horizontal crossbar and pulling the vacuum tank door towards the tank. Activation of the hydraulic cylinder also causes a connection point of the lower linkage arm and the upper linkage arm to move over-center of the connection between the lower linkage arm to the to the tank creating a tight seal between the vacuum tank door and the tank.

System for joining containers for a first container (1) with doors at the front and rear thereof and a second container (2) with at least one door at the rear thereof, attached by the smaller sides, which comprises four hooks (3) on the four corners of the containers (1, 2), a plurality of sheets (4, 5) on the interior edge at the rear of the containers (1, 2) fixable to both and which cover the entire interior perimeter of the containers (1, 2), and means for adjusting the identification number of the containers (1, 2).

The means for adjusting the identification number can comprise a series of electronic screens (101, 102) on each container (1, 2) with two control units (102, 202), power sources, and communication means between the control units (102, 202) and optionally a contact (103, 203) in the support area of a sheet (4, 5).

A housing for inspecting and replacing a wear plate maintained within the interior of the delivery unit compartment without entering the confined space compartment.

A cargo container having a plurality of weighing sensors disposed under a plurality of floor panels for accurately weighing the contents within the cargo container and displaying an accurate weight of the contents of the cargo container for shipping purposes.

A foldable container enables the entire height of a folded state thereof to be one fifth of the entire height of the state of being folded, such that the height of an international standard container can be satisfied even though empty containers are stacked in five stages. To this end, the hexagonal foldable container can include an upper panel part and a lower panel part respectively forming the upper surface and lower surface thereof; a left panel part and a right panel part respectively forming the left surface and right surface thereof, and respectively folded; a front panel part and a rear panel part respectively forming the front surface and rear surface thereof; and a fixing bar provided at the outer surface of the rear panel part.

A modular facility formation system includes any number of modules that may be coupled to one another to create a facility. Walls of the facility may be provided by one or more removeable walls, the walls of a shipping container, or a combination thereof. When installed within a shipping container, upper and lower braces are pressure fit into the shipping container without penetrating the container. The lower braces are configured to engage guidance mechanisms of the modules to guide the modules into a stowage position within the shipping container and to secure the modules in place. The modules may be configured with a pre-determined internal configuration corresponding to a defined function of the room within the facility.

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.

A hollow container or box formed from a top panel, a first side panel, a second side panel, opposed end panels, and a base panel placing the container or box in a fully assembled position. The second side panel is releasably coupled to the base panel and each of the other panels are hingedly coupled to one another. Upon rotating each of the opposed end panels, the top panel, the first side panel, and the second side panel relative to one another and various axis rotation in combination with releasably detaching the second side panel from the base panel, the container or box is transitioned from a fully assembled position into a flat, parallel orientation, fully collapsed position.
