6.5.3 Extension of stabilizing jacks
Before extending the jacks of the Ruthmann-Steiger the working range and
the correspondingly necessary supporting basis must be fixed. The follow-
ing jack base positions are e.g. possible:

Full extension of stabilizing jacks,
All jack arms are completely extended horizontally.

Unilateral extension of jacks within vehicle profile,
The jack arms remain unilaterally horizontally completely in their
retracted position. They are extended horizontally on the opposite
side.

Extension of jacks on both sides within vehicle profile.
The jack arms remain completely retracted on both sides in hori-
zontal position.

Minimum jacking.
The jack arms remain completely retracted on both sides in hori-
zontal position. The rear jacks have ground contact
– the position
of the front jacks is variable / not relevant.
The jack arm must either completely be extended horizontally or complete-
ly be retracted horizontally. Intermediate positions for the horizontal exten-
sion are forbidden. The computer control recognizes, in relation to the de-
gree of extension of the jack arms and the interrogation of the ground-
contact of the jack-cylinders, the working range permissible for that jacking
situation.

For extension of the jacks there must be sufficient space available.

Keep sufficient distance to pits and embankments (see e.g. German
Standards DIN 4124 „Construction Pits and Ditches“).

The jack plates must have horizontal contact with the ground and must
not jam. They must be freely moveable during positioning procedure.

The Ruthmann-Steiger must not be able to slip.

In case of insufficient jack stroke the jack plates must be supported ac-
cordingly.

The jacks have to be extended at least until the boom movement is re-
leased by the main control. All jacks must have ground contact. For min-
imum jacking only the rear stabilizing jacks must have ground contact.
The position of the front jacks in this case is not relevant.

For the working range with „full jacking“, „unilateral jacking within the
vehicle profile“ or „jacking within the vehicle profile on both sides“ the
