INTRODUCTION GB
6.1 Driving off-the-road and on the
clamp silo
Danger of tilting on steep terrain!
When driving in the clamp silo and on terrain, be aware
of edges, ditches and loose underground! High danger of
tilting with no load on the tire edges of the outer tires!
6.2. Driving on the road
A particular danger on the road are sloping road verges.
Centrifugal forces resulting from fast cornering can have
a negative impact on the stability.
When driving on the road with the speed exceeding 25
km/h it is recommended to block the trailing axle.
Blocking the trailing axle will lead to a
higher smoothness of running and higher
safety!
It is not
allowed
to drive in too
steep a terrain!
The outer
tires
shall be on solid
ground!
Centrifugal forces
resulting from fast
cornering can tilt

13. Technique
13.1 Pendulum equalizer
The 8-wheel chassis has an excellent ground performance.
This feature is the basis for optimum and low ground
pressure!
13.1.1 Pendulum equalizer in direction of
motion
13.1.2 Pendulum equalizer in cross-direction of
motion
13.2 Hydraulic suspension with
automatic height control (option)
The hydraulic suspension is divided into two subsystems,
direction of motion left and right. The two spring cylinders
(1) at one side and the two gas storage tanks (2) form a
system. With a changed load, the height is controlled by
adding oil from the hydraulic block (3). The hydraulic block
is activated electro-hydraulically.
The hydraulic power is pro-vided by the LS-capable 3-way
current dividing coil (4) which is integrated in the on-board
hydraulic of the trailer.
The height is determined by the linkage of the height
control (5).
TECHNIQUE
- 18 -
0700_GB-TECHNIK-KA_549
TECHNIQUE GB
The regulation is carried out by the electronic system, a
Siemens LOGO (6), in the control box. The control system
requires a voltage of 12V and is secured by a fuse (7) 10
A. The diode (8) integrated in the cabling protects the line
from excess voltage (e.g. due to welding work).
13.3 Trailing axle
The trailing axle of the chassis 8-18SL differs significantly
from known trailing axle systems. The crank of a lever
between center of motion (1) and load application point
(2) is long. For the steering motion the sledge (3) must
travel sideward. The motions are smoother but need more
energy, too. This higher expenditure of energy has a posi-
tive impact. As with the „Standard“ steering type axle, the
turning out does not cause any problems. However, this
steering type can transfer more lateral forces.
In order to manoeuvre with the chassis 8-18SL the steering
type axle can be hydraulically centred. The centring force
is sufficient for up to 12 tons axle load (on the steering
type axle) on asphalt.
