A dunnage bag may have stripes on its sides that extend from a top edge to a bottom edge of the bag. When the bag is inflated, one or more of the stripes may be visible to a user viewing an end of the bag. A number and width of stripes visible to a user may indicate a width of the dunnage bag, a corresponding width of the gap within which the bag is positioned, and an amount the bag that is in contact with surfaces of adjacent cargo. The user may note an outermost visible and determine that the bag has a width within a range of widths associated with such outermost visible stripe, and whether such width allows for the bag to be used safely. If a stop stripe is visible, the gap is too wide for the bag.

A novel securing device includes a frame having an anchor, a tether coupled to the anchor, and an attachment device coupled to the frame. The attachment device is configured to facilitate selective attachment to a planar surface. In a particular embodiment, the attachment device is a magnetic attachment device. Optionally, the magnetic attachment device is encased between the frame and a cover that prevents scratching of the planar surface to which the device is secured. In another particular embodiment, the attachment device is a suction cup. The magnetic attachment device and the suction cup may be interchangeable.

A cargo restraint system includes a driving shaft, a first restraint, and a second restraint. The first restraint is operatively coupled to the driving shaft via a first indexing mechanism arrangement. The second restraint is operatively coupled to the driving shaft via a second indexing mechanism arrangement. The first and second indexing mechanism arrangements are arranged such that rotation of the driving shaft in a first rotational direction causes the first restraint to rotate between a lowered position and a raised position, and further rotation of the driving shaft in the same rotational direction causes the second restraint to rotate between the lowered position and the raised position. The first restraint may be axially offset from the second restraint to allow sequential loading and unloading of cargo.

Various embodiments of the present disclosure provide an electronic inflator configured to direct pressurized air into an inflatable object, to monitor the air pressure inside the inflatable object, and to automatically stop directing pressurized air into the inflatable object after determining that the air pressure inside the inflatable object has reached a preset pressure.

The present disclosure is directed to dunnage bags formed using polyethylene terephthalate (PET) and processes for manufacturing these PET dunnage bags. Generally, the PET dunnage bags of the present disclosure include a PET outer bag, an inner bladder enclosed within the PET outer bag, and a valve assembly that enables air to be introduced into (or escape out of) the inner bladder to inflate (or deflate) the inner bladder, thereby inflating (or deflating) the PET dunnage bag.

A dunnage bag air valve adapter can be coupled to a dunnage bag air valve to allow a user to inflate the dunnage bag using an inflation tool having an inflation tool head with which the dunnage bag's air valve may be otherwise incompatible.

A dunnage bag and load strap hanger apparatus includes a dunnage bag and load strap hanger and a handle mounted applicator block operative to support and affix the dunnage bag and load strap hanger. The hanger is fabricated from three distinct and separate parts: a generally planar support substrate, adhesive patches or regions on the support substrate, and release paper covering the adhesive patches. The support substrate in some embodiments is a sheet that is further divided into two contact members separated by a resilient coupler. Each contact member preferably has a contact body, a hanging loop distal to the resilient coupler, and in alternative embodiments an adhesive coating or other fasteners and affixers. In one embodiment there is one affixing surface, and a fastener to couple two contact members together to support a load strap. In another alternative embodiment a load strap is woven through a pair of slots.

A sheet of flexible material can be deployed or stored by unfurling or furling the sheet using one or more inflatables. After the sheet is deployed to, for example, cover a load on a flatbed trailer, the inflatable can be deflated for storage. A sheet that has been removed from the load can be stored by placing an inflatable along an edge of the sheet. The inflatable is pressurized, and the sheet is furled onto the inflatable by rolling the inflatable. The inflatable is deflated and rolled up with the sheet for storage.
