MAN.241 Rev.5 ENG - Use and maintenance manual S23 page 47 of 127
Avoid contact of the aerial part with fixed
objects (buildings, etc.) or with moving ob-
jects (vehicles, lifting equipment, etc.).
4.4.5.1 Moment limiter (*optional)
Thanks to a moment limiter device (anti-
tipping device fitted as standard on this
MEWP), all operations bringing the ma-
chine over the working diagram are inef-
fective.
When the maximum allowable outreach is almost
reached (90%), the pre-alarm indicator 7 lights up
(Picture 9).
When the maximum allowable outreach is reached
(see the working diagram in Picture 2), the alarm in-
dicator 15 lights up (Picture 9) and boom lifting/ex-
tension operations are blocked.
4.4.5.2 Load limiter (*optional)
Moreover, when the MEWP exceeds its
maximum permitted capacity (200 Kg/441
lb.), the logic system detects the overload
and stops the work operations, warning
with a continuous acoustic signal.
During the movement of the MEWP aerial part,
reaching the maximum load selected, the load limiter
safety device activates:
o Overload until 20 Kg (signaled by the lighting
of the intermittent block light 23 – Picture 9
and by an intermittent acoustic warning): in
this case, operations remain active, even if
these two signals warn the user about the
danger; the signals will stop only removing the
overload from the basket.
o Overload > 20 Kg (indicated by the fix lighting
of the block light 23 – Picture 9 and by a con-
tinuous acoustic warning): the load limiter
safety device stops all operations of the ex-
tendable structure.
➔ The operator must remove the overload from
the basket to continue the work with the
MEWP.
