Superstructure stability
The stability of the superstructure is ob-
tained by a variety of constructive meas-
ures and components.
► Do not make any changes to the deliv-
ery condition of the superstructure.
► Use the intended tensioning devices.
► Observe the instructions from the load
security certificates concerning the
components used.
Dangers while driving
There is a risk of impact on bridges, in tun-
nels or with other structures. Persons can
be injured or the vehicle, the transported
goods, and the structure can be severely
damaged.
► Observe the vehicle dimensions incl.
the transported goods.
► Observe the permissible passage di-
mensions (height, width).
Dangers when manoeuvring, coupling
and uncoupling
When manoeuvring or coupling and un-
coupling, there is a lethal risk of crushing
for persons standing between the tractor
unit and the trailer as well as in the coup-
ling area.
► Only drive in reverse when nobody is
endangered.
► Only manoeuvre with a guiding assist-
ant.
► Before uncoupling, secure the trailer
additionally with wheel chocks against
accidental movement.
► Instruct all persons to leave the area
between the tractor unit and the trailer
during the coupling procedure.
Dangers when parking and unhitching
Accidental trailer movements, unstable
ground and poor securing at night can
cause serious accidents and injuries.
► Actuate the parking brake when un-
hitching.
► Also use wheel chocks on the wheels.
► When parking the trailer in a public
traffic area during the hours of dark-
ness, the vehicle should be particularly
marked in accordance with the legal

Incorrect load distribution as well as im-
properly secured loads can lead to danger-
ous road handling and serious accidents or
damage to the vehicle.
INFO
Observe the load distribution plan for op-
timum loading. The load distribution plan
is individually calculated for every trailer.
Using the load distribution curve, you can
read the distance that must be maintained
between the front wall and the load.
► Observe the specified axle loads and
drawbar loads.
► Secure the load in accordance with the
applicable regulations.
► Ensure that the load securing aids are
not damaged and are functional.
