1
Prior to inflation, the load is solidly supported
on landing pads. These pads protect the Air-Caster's
torus bag from being crushed when the load is at rest.
Step
2
When air is applied to the Air-Caster, the torus bag
inflates, creating a seal against the floor surface
and raising the load.
Step
3
When the pressure within the chamber is sufficient
to offset the load's weight, air evenly escapes between
the flexible torus bag and the floor. The load
is literally floated on a thin, nearly frictionless
cushion of air, .003 to .005 inches (.08 to .13mm)
thick.
