For each stabilising beam the last manoeuvre shall be the lowering of the
stabiliser.
Remember that the crane may only exceptionally operate at full power up to a
maximum inclination of the base of 5.7° equal to an angle of approximately 10% and
only to a boom extension equal to 11 m.
NOTE: DO NOT OPERATE THE EXTENSION OR RETRACTION CONTROL WHEN THE
STABILIZERS ARE RESTING ON THE GROUND.
DANGER OF OVERTURNING
It is also necessary to keep to the following rules for stabilisation
:
A) Before using the crane, make sure all of the stabilisers are completely
extended and resting on the ground, independently whatever the sector you
are operating in.
B) The wheels of the vehicle must not be completely off the ground.
Whenever working off the road, on soft ground or asphalt, arrange
distribution plates under the stabilisers (supplied on request) or planks of
wood of a suitable thickness to reduce the pressure.
Check that the stabiliser supporting surface is suitable because should one of
the stabilisers sink in, the vehicle will overturn. In particular, make sure the
stabilisers do not rest on drain covers, over cavities or on any surface that is
not sufficiently resistant.
In difficult working conditions, the crane transmits a force to the stabiliser
which may be as high as 16000 daN.
DANGER OF SHEARING
GENERAL NOTE ON SAFETY:
WHEN OPERATING THE STABILIZERS, MAKE SURE ALL LIMBS ARE KEPT WELL
AWAY FROM THE DANGER AREA TO PREVENT CRUSHING. IN PARTICULAR
KEEP YOUR HANDS ON THE CONTROLS, WELL AWAY FROM ANY MOVING
PARTS AND KEEP YOUR FEET OUTSIDE THE AREA WHERE THE CRANE IS
STANDING.
