General information
Pic. 18 Air-suspension
1 Air bellows

The raising / lowering device consists of
air bellows (Pic. 18 /1) that prepare the
trailer for loading / unloading by taking in
or releasing air.
Air-suspension is also used to keep the
driving level of the trailer in "driving
mode" at the same height, irrespective of
its load. Filling and releasing is controlled
by using a pivoted lever.
The axle assembly is controlled by the
raising/lowering valve at the same time.
