3.3 Emergency control stations
3.3.1 Outriggers control station
Picture 39: hydraulic distributor of
stabilization control station.
Through the control station in Picture 39, located on the
left side of machine frame, it is possible to perform
manual stabilization/destabilization of the machine and
to widen/narrow the tracks (par. 4.4.2.1).
The machine in travel position is meant with the
basket on the rear.
In addition, there is an emergency red mushroom-
shaped button EB (Picture 39) that blocks the machine,
removing the power supply to the control circuits. This
button has priority over all other commands; thus, it
allows only manual descent to the ground. The
emergency button has a mechanical locking device;
therefore, it must be unlocked by turning it clockwise to
reactivate the normal machine working.
