Emergency manoeuvres
Before starting the emergency procedures, it could be useful to
contact C.M.C. Service and communicate errors data.
In case of emergency, the controls of the MEWP aerial part should be
performed by the operator on the ground.
4.6.1
Emergency buttons
In case of emergency, push the emergency button
: the MEWP engine
switches off and all operations are disabled. This button has priority over
all other commands.
The emergency button has a mechanical locking device, therefore, to re-
store normal working conditions, it must be unlocked by turning it clock-
wise.
On the machine, there are emergency buttons in the following positions:
•
on the centre of basket control station;
•
on the centre of radio control station;
•
on the left side of outriggers control station.
In order to secure the machine, perform the following procedures in the
chronological order indicated:
1. recovery of the aerial part;
2. closing of the stabilizers;
3. retraction and travel of the tracks.
4.6.2
Emergency bypass
In case of the basket operator pressed the emergency button and were
unable to reset this button at the original position (due to blackout, fainting
or other), it will be possible to disable that safety function through
the
“emergency bypass” under the yellow cap
(Picture 29) located on the
left side of the switching on/off box.
The ground operator removes a safety lead seal and disable the emergen-
cy through
an internal on/off lever.
It will be care and responsibility of the operators, at the end of the
operations, to reset the original conditions, including the resealing
with seal compulsorily branded “C.M.C.”.
4.6.3
Hydraulic system failure
In case of emergency (fuel run out and/or breakage of a hydraulic part),
you can use the electric engine (*optional) or the electropump (*optional), if
installed.
If the electropump is started, carry out the recovery operations through the
emergency control station (Picture 15).
In case of absence of this optional, the manual pump can be used for
emergency recovery of the MEWP. Bring the manual pump handle and in-
sert it in the proper point of pumping (Picture 20).
