™
Air Lift System
The Auto-PosiLift
™
feature is programmed to automatically
lift an axle when only one (or two axles on the CBX69) are
required. The system senses that only one or two axles are
necessary to carry the load
(Figure 26)
.
The Auto-PosiLift
™
tractor power is engaged.
With the power on the trailer parking brakes released
(no vehicle motion required), the system's pressure sensor
in the air valve system reads the air spring pressure and
determines to automatically raise an axle or leave all axles
in the down position
(Figure 27)
.
The Auto-PosiLift
™
tractor power is disengaged.
With the tractor power off, or the trailer parking brakes
engaged, the system automatically deploys all axles to
the down position
(Figure 27)
.
The Auto-PosiLift
™
vehicle is in transit.
When the vehicle is in motion, the position of the lift
axle will remain constant (either up or down). In the event
of a loss of power, all axles will automatically deploy to
the down position
