4. Lifting axles: lifting axle functions and their
operation
What do we mean by “lifting axles”?
Simple: lifting axles are axles that can lift themselves o the ground by means of lifting
bellows. However, an axle can have lifting axle functions without having lifting bellows.
Without these lifting axle bellows, only the pressure in the air suspension is reduced, which
means that the axle no longer carries a load, but still rests on the ground under its own
weight. We therefore distinguish between “lifting axles” and “lifting axle functions”.
9Lifting axles: axles equipped with lifting bellows, and thus capable
of detaching from the ground.
9Lifting axle functions: all (automatic) functions related to
manipulating the pressure in the air suspension bellows, even
without the axle being visibly detached from the ground.
Lifting axle control: manual operation of the lifting
axle(s)
Purpose of this function: to manually lift and lower any lifting axles on the trailer by using
the Smartboard.
This function only works on vehicles equipped with lifting bellows. When these are not
tted, this function does nothing.
The lift axles always return automatically to the conguration congured by STAS from a
speed of 15 km/h.
