Air Bag Definition & Functions• Introduction:

• A dunnage air bag is a poly bladder surrounded by numerous plys of paper, equipped with an inflation valve, and is used to minimize front-to-back load shifting in tractor trailers, railcars, and overseas containers.

• Characteristics of an Air Bag

• Compacting or positioning the lading• Compacting and positioning takes place during air bag inflation. The air bag

surface pushes uniformly out against the load. As the air pressure increases, it overcomes frictional forces, eliminating small voids remaining in the load. No matter how tightly a load is positioned, either by fork truck or by hand, a build-up of small voids will remain. These voids are eliminated by air bag compacting/positioning.

• Cushioning the lading• The second characteristic of air bag bracing is the cushioning that occurs during

impact. For example, when a railcar is humped, the compacted lading in the front half acts as one unit rather than individual units which can slam into one another. The rear half of the load is cushioned by squeezing the air bag, increasing its internal air pressure, until equalization of forces occurs. The cushioning effect diminishes the shock of impact.

Air Bag Definition & Functions

• Repositioning the lading• When the forward motion of the lading ceases, repositioning of the lading begins.

After the lading moves forward, squeezing the air bag, the internal pressure is greatest. The increased air pressure is reduced by pushing the lading back to its original position when the forces stop. Both the cushioning and repositioning of the load will take place in a fraction of a second.

• Enlarging the void size after inflation

• The fourth characteristic of air bag bracing is its ability to fill an increased void as the lading settles. Even with rigid products, which have been tightly loaded, settling takes place. In-transit vibration causes the lading to loosen. With other types of bracing, constant pressure cannot be exerted on the load. Air bags have the ability to expand, thus maintaining somewhat reduced but continuous pressure.
