6.5.4 Boom movements
Boom movements are only permissible, if the jacks of the Ruthmann-
Steiger are properly extended.
Danger!
Other persons, things and the Ruthmann-Steiger can be
endangered through Steiger movements. The Ruth-
mann-Steiger can be damaged so much by touching e.g.
an obstacle that the safety of the personnel in the work-
ing cage is no longer guaranteed. Important construc-
tion components (e.g. bolts, hydraulic components etc.)
can be damaged or ripped down so that it can lead to
serious accidents. The operating staff has to ensure
during all movements of the Ruthmann-Steiger, that it
does not endanger itself or other persons! It is not per-
mitted to touch obstacles / things with the Ruthmann-
Steiger, with the working cage or the with the booms.
Steiger movements are only permissible, when the
working range can be seen over. This concerns the area
below the working cage, too.
Pre-condition:
extend the jacks of the Ruthmann-Steiger properly.
In case of proper jacking the following pilot lamps will shine at operating
