A container refrigeration unit (10) is provided. The container refrigeration unit includes a container (20), a curtain (30), a seal element (40) and a sealing adapter (50). The container includes sidewalls defining an open end (26) and a curtain track (27) proximate the open end. The curtain is sized to cover the open end. The sealing adapter is fittable to the curtain track. An entire periphery of the curtain and an entirety of the seal element are sequentially fittable to the sealing adapter.

A tarp apparatus includes a bendable and foldable heavy duty tarp designed to cover the exposed end of receiver boxes and waste haulers to keep refuse in during transit. The tarp apparatus folds for easy storage, is made of heavy duty geotextile or any pliable material, and is reinforced with webbing for strength, with grommets and loops for additional attachment points. In addition, attached webbing and hooks easily secure the tarp apparatus to receiver boxes and/or waste hauler trucks while attached cam buckles or ratchets tight the tarp apparatus securely to the receiver boxes and/or waste haulers.

A fabric closure for the open end of an air cargo container having a fabric door and a fastening system for connecting the opposed side edges of the fabric door to couplings attached to the container. The fastening system includes at least one fabric pocket, a protective strip attached to the outer surface of the pocket, and a connecting strap for being secured around a respective coupling. The connecting strap passes through the fabric pocket and is engaged with a hook and loop fastener portion on the protective strip.

A method of loading a flexible enclosure, and the flexible enclosure. The enclosure has a floor, a sealable port, and a top enclosure. The top enclosure has an opening that is sealingly closable with an airtight closure. The method includes the steps of selecting a parking location for the enclosure, and positioning the enclosure over the parking location. Equipment, such as a vehicle is loaded in the enclosure. The enclosure is sealed, and the internal atmosphere of the enclosure is modified, such as lowering the oxygen content of the interior atmosphere.

A door and locking system for a rear opening of a long bed trailer, the rear opening having a top edge, a bottom edge and first and second side edges, the door and locking system has a canvas door configured for mounting adjacent to the rear opening of the long bed trailer. The canvas door can move between a closed position in which the canvas door moves to close the rear opening and an open position in which the canvas door moves to open the rear opening. A locking system secured to the edges of the rear opening can move between a locked position, in which the locking system is in locking engagement with the canvas door in the closed position to secure the canvas door against the edges of the rear opening to close the opening for retaining fluidizable product in the long bed trailer and an unlocked position, in which the locking system is free from locking engagement with the canvas door to allow the canvas door to move into the open position.

Methods of transporting a plurality of freight containers are disclosed, including stacking one or more containers on a transportation vehicle, where one or more of the stacked containers is a vertically collapsible container in a collapsed position, where at least one of the vertically collapsible containers includes: a frame assembly including: a plurality of rectangular frame members; a plurality of articulated vertical frame members disposed between the rectangular frame members; and where the articulated vertical frame members are positioned and arranged to retract to within the frame assembly; a lifting mechanism positioned and arranged to elevate the rectangular frame members from each other; and where the lifting mechanism is disposed between the uppermost rectangular frame member of the frame assembly and the lowermost rectangular frame member of the frame assembly.

An air cargo container has a tubular head rail extending across the front opening of the container. Sliders are provided in or on the head rail. A curtain door has sheet of flexible material and flexible straps attached to the sheet. The straps are attached to the sliders. The curtain door may be opened and closed via the sliders sliding along the head rail.

A curtain closure for the cargo opening of an air cargo container and the air cargo containers that have the same. The curtain closures include a fabric layer, and at least one of an insulating layer or a reinforcing layer attached to the inside of the fabric layer.

Embodiments of the invention described herein thus provide systems and methods for improved securement of a cargo cover/flexible door to a cargo container. The systems generally provide securement using cooperating frame securement features positioned on the cargo container and securement plates positioned on door straps of the cargo cover.
