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

the trailer!

The gas pressure shall be checked every two years and

the filling shall be completed!

Maintenance work at the gas storage tank

shall be carried out by experts only!

A special filling and checking device is necessary to

check the gas pressure and to refill the storage tank. For

checking the gas filling, the oil side of the storage tank

shall be pressure-free. Therefore the spring cylinders

need to be lowered completely with the manual mode

of the control device. Pre-stress of the gas storage tank:

20 bar +/-2 bar!

The storage tank shall be filled with nitrogen only. The

utilisation of oxygen or air may cause explosions!

12.2.4 Pressure control valve of the suspension

systems

The suspension circuits are equipped with pressure control

valves which absorb pressure peaks by blows. The valves

are positioned in the hydraulic block at the chassis front.

The pick-up pressure of the valves shall be checked every

year! Procedure:

1. Connect a manometer to the backside of the measuring

point of the left suspension circuit

2. Fully extract the spring cylinders by aid of the manual

steering mode until the pressure control valve is

triggered.

3. Read out the manometer: psoll= 170 +/-10 bar

4. Repeat this action for the right side!

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
