It is strictly forbidden to use the MEWP
when the load limiter warning is on. Re-
move the exceeding load from the basket
until the acoustic signal and the relative
light go out.
4.4.5.3 Slowdown of the aerial part maneu-
vers
Slowdowns can be set by software for start and end
of each aerial part maneuver (lifting/lowering of arms,
extension/retraction of arms, clockwise/ anticlock-
wise rotation of the turret, opening/closing jib), valid
in the following conditions:
o Arm angle;
o Arm extension;
o Opening jib;
o Pre-alarm condition (90% of the block);
o Approaching the turret angle to a curve
change zone.
4.4.5.4 Anti-crash system
When the machine is stabilized in the predefined ar-
eas, both with tracks resting on the ground and
raised, the stabilizers with their curved structure can
reach a height greater than that of the machine
frame.
Furthermore, the engine pack with the fuel tank has
a considerable bulk, which comes out from the rear
shape of the chassis.
The anti-crash system, supplied as standard device,
does not allow the aerial part (pantograph, boom, jib)
to have accidental impacts with these bulky parts
mounted on the frame and the stabilizers, blocking
the movements operated by means of logic parame-
ters set via software.
When activated, it is signalled by the warning light 6
(Figure 9) on the electronic panel of the radio control
or wired remote control.
When the warning light 6 will be flashing and
will be associated with an audible alert, the
machine will be in "anti-crash block” (colli-
sion danger). In order to unlock the machine,
it is necessary to press the parking button P
on the radio control together with the desired
manoeuvre.
If, during the descent of the pantograph or booms, the
machine gets blocked (anti-crash warning light on), it will
be necessary to continue the closing operations by press-
ing and holding the parking button P simultaneously to
the desired operation. The sudden or intentional release
