Air suspension
!
WARNING
Risk of accident due to fully lowered or
raised vehicle!
Failure to set the air suspension to the
"Drive" position before starting off can res-
ult in a risk of accidents due to impaired
driving characteristics or vehicle collisions
in passageways.
► Always move the air suspension into
driving position before driving off. The
only exception is manoeuvring at
walking speed.
CAUTION
Risk of injury due to crushing!
When lowering the trailer, the clearance
under the trailer is reduced. Persons
between the road and vehicle parts can be
crushed and seriously injured.
► Avoid the danger areas.
► When operating the air suspension,
avoid having persons underneath the
trailer.
NOTE
Material damage due to grounding!
On vehicles with a large lifting height, the
distance between the ground and suspen-
sion elements is reduced when reaching
maximum lifting height. The spring ele-
ments on the axle could ground when
manoeuvring and be damaged.
► For vehicles with large lifting heights,
always put the air suspension in driv-
ing position.
KRONE trailers are equipped with an air
suspension system. The vehicle height
(e.g. to adjust it for a ramp) can be adjus-
ted in two ways:
○
Manually
○
Electronically controlled
Also observe the enclosed supplier
documentation.
Depending on the make and design of the
lifting and lowering valves, the following
functions can be carried out using the air
suspension's control lever:
Control lever
position
Function
Drive*
The trailer is always kept at the
same height, regardless of the
load.
Raised
The trailer is raised, e.g. to ad-
just it for a ramp.
Raised and
engaged
The trailer is raised to the max-
imum possible lifting height.
Lowered
The trailer is lowered, e.g. to
adjust it for a ramp.
Lowered and
engaged
The trailer is lowered down to
its mechanical limit (air sus-
pension bellow without over-
pressure)
Stop
The trailer height achieved via
lifting or lowering is main-
tained.
* The driving position cannot be set manu-
ally on electronically controlled air suspen-
sion. Instead, the ride height is automatic-
ally set at a driving speed of > 15 km/h.
The operating instructions for the air sus-
pension's control lever are shown as a pic-
togram on the control unit.
