A container floor assembly includes a floor unit, a blocking member and a limiting member, wherein the blocking member is supported on the floor unit, and the limiting member detachably connects the floor unit and the blocking member in a manner of restricting a relative lateral movement of the blocking member and the floor unit. Each of the blocking member and the floor unit is provided with a limiting structure, the limiting member is detachable and connected to the limiting structures in the blocking member and the floor unit simultaneously. The floor unit includes a floor body and a floor chassis, the floor body is mounted on the floor chassis, and the blocking member is supported on the floor body.

Systems and methods for delivering a requested payload using an autonomous delivery vehicle are described herein. In some embodiments, a cargo system for use with an autonomous delivery vehicle can include a frame defining a cargo space having an opening. A plurality of partitions can be positioned within the cargo space and configured to divide the cargo space into compartments. In some embodiments, the partitions are movable so that the cargo space can be divided into efficiently-sized compartments based on, for example, size characteristics of the payload. The cargo system can further include an access system configured to selectively define an aperture over the opening of the cargo space. The access system can vary the size and position of the aperture to provide access to only a selected one of the compartments regardless of the size and/or position of the selected compartment.

A tank assembly for a helicopter is provided. The tank assembly comprises a retractable tank for storing liquid or other substances. The retractable tank comprises an upper frame structure. The tank assembly further comprises an attachment mechanism attached to the upper frame structure and configured to engage a main rotor transmission of the helicopter to suspend therefrom. A helicopter comprising a fuselage, a main rotor transmission, and a tank assembly is also provided.

A sealing structure and a refrigerated container having same. The sealing structure comprises a base, a protruding portion, a deforming portion, and connections through holes. The base is a bar having a predetermined thickness. The protruding portion and the deforming portion are on a sealing surface of the base, and are configured to protrude outwards relative to the sealing surface and extend lengthwise along the base. The deforming portion extends by the same length as but higher than the protruding portion. When the deforming portion is subjected to a force toward the sealing surface, the height decreases. The holes are between the protruding portion and the deforming portion along the base. The holes are spaced apart from each other in the lengthwise direction of the base. The performance of the sealing structure improves hermeticity of products, reduces quality risks, and ensures pressure-resistance installation and anti-weathering performance that extends service life.

A fluid storage tank has a base structure, perimeter columns extending upward from the base structure and a flexible bladder contained within the perimeter columns to define a boundary of the tank. The base structure is arranged to be supported on a supporting foundation to span a bottom of the tank. The upright columns are releasably coupled to the base structure and extend upward at circumferentially spaced apart positions about a perimeter of the tank in a working position of the columns. The upright columns are collapsible from the working position to a transport position in which the columns are arranged to be bundled alongside ne another. The flexible bladder is coupled to the upright columns and contains a fluid within the tank in the working position while being collapsible within the columns into the transport position.

A gas turbine storage container is composed of a horizontal cylindrical shell with openings at two opposite ends of the cylinder, outside is designed with frames to keep it fixed and has straps to install ropes when hoisting. The inside of the cylindrical shell is pumped with inert gas and contains desiccant. The engine is housed in a mount that can be fixed to the inside of the box, and has wheels to make it possible to move it out of the box. A sensor system that measures the temperature and humidity status inside the cylindrical shell can provide information about the quality of the gas stored in the cylindrical shell in real time without opening.

Methods and apparatuses for shipping of fabricated rectangular wooden modules used for construction of a wood frame structure and for shipping of other bulky items are described. In particular, the disclosure features a modified shipping container for shipping the fabricated rectangular wooden modules and methods of loading, transporting, and unloading the fabricated rectangular wooden modules. The modified shipping container features a removable header system and a removable cover. The fabricated rectangular wooden modules include a module length axis, a module width axis, a bounded wood perimeter, and joists or rafters oriented perpendicularly to the module length axis, and are stacked as cargo in the interior of the container such that joists or rafters of the fabricated rectangular wooden modules are substantially vertical and the length axes of the modules are substantially parallel to a length axis of the container.

A corrugated corner element including at least some of a portion of material extending from a first terminal end to a second terminal end; a first corner element leg having one or more alternating ridges and grooves; a second corner element leg, extending from the first corner element leg, the second corner element leg having one or more alternating ridges and grooves; and a score mark formed in the portion of material, extending from an area proximate the first terminal end to an area proximate the second terminal end, wherein the score mark provides a line or portion along which the corrugated corner element may be bent or folded.

The present disclosure provides several novel improvements to freight storage and transportation services. In one detailed though non-limiting aspect, methods and means for safely and efficiently adjusting the interior volume space of an otherwise fixed-volume storage and transportation container are provided.

The invention is directed to a portable container system comprising a container which comprises a floor, four upwardly-extending sidewalls, wherein at least one of the sidewalls is hinged to allow the at least one sidewall to open outwardly, and a top wall. The system also comprises a plurality of skids contained within the container. Each skid comprises a base and one or more upwardly extending members; and one or more cabinets mounted on the base or one or more upwardly extending members, wherein the one or more cabinets comprise: control power distribution panel cabinets, human-machine interface cabinets, programmable logic controller-redundancy cabinets, network cabinets, or remote I/O cabinets.
