To optimize load distribution on multi-axle units.
To provide for auxiliary axle pick up when the axle is not need to use.
So it can provid operating economies and improved
maneuverability.
To permit automatic level. With automatic height sensors,
there is no change in vehicle height from an unloaded to a fully
loaded condition. GUOMAT air spring permits the cargo space to be designed
with a higher top and a lower floor without interfering with the
tires while still staying within maximum vehicle height limits.
A constant height is maintained when it use at loading docks
and for trailer pick-ups.
