10.2 Supporting plates with relieving
The supporting plates are made of plastic. The bottom is rubber impreg-
nated. It reduces the risk of damages of the ground and increases the skid
resisting properties. Through the relieving on the upper side of the support-
ing plates we obtain a higher degree of safety against a “slump” of the
Ruthmann-Steiger. The recessed grips mounted on the supporting plates
facilitate the handling of the plates.

When using in general the supporting plates, take also in consideration
a change of the slipping risk owing to e.g. influence of the weather such
as snow and ice in winter or humidity by rain and/or fog. Hereby the skid
resisting properties can be reduced.

The supporting plates must not be damaged and must be free from ice,
oil, grease or other lubricants.

Please observe the general information concerning the admissible sur-
face pressures. Take also in consideration admissible surface pres-
sures, which are changing due to e.g. influence of the weather.

It is not allowed to heap up several above mentioned supporting plates
under the jack plates!

It must be assured that the jack plates are exactly inside the relieving of
the supporting plates after the positioning of the Ruthmann-Steiger.

It is not allowed to press the supporting plate in the earth on one side by
exceeding locally the admissible surface pressure of the ground. Be-
cause of that the supporting plates might so incline that the stabilizing
jacks might roll-off or might be damaged. - Danger of tilting! -

The operating staff are now as ever reliable for the safe positioning
of the Ruthmann-Steiger. The use of the supporting plates does not
replace the duty of the operating staff to exercise care.

If necessary the Ruthmann-Steiger must be secured against slipping
through other suitable measurements.
