4.5 SAFETY AND EMERGENCY DEVICES
These devices are an integral part of the platform and act in terms of security depending on the
configuration of the platform.
A) Moment limiting device
It is made up of an electronic system, which senses automatically the load in basket (max 250kg) and keeps
the horizontal outreach within the permitted measures, as to the angle of the main boom. Once reached
the max permitted measure, both the main boom lowering, the extraction of the extractable elements and
the jib boom lifting are stopped. To reset operations you have to retract the extractable elements and/or
lift the main boom.
IMPORTANT: This device is extremely important as to safety, since it avoids the rollover of
the machine and the structural overload.
B) Basket balancing device
It is a hydraulic device integrated in the main circuit by means of 2 oil-pressure cylinders which keep the
basket balanced automatically in every working position of the boom. In case the basket is not balanced
perfectly, it is possible to act by hand, following the procedure described below.
ATTENTION: CARRY OUT THE CORRECTION OF THE BASKET LEVELLING WITH CARE AND
WITHOUT MATERIAL IN THE BASKET. THE PLATFORM HAS TO BE IN REST POSITION
Procedure:
1. stabilize the platform
2. lift the main boom for having approximately an angle of 2° (no more)
3. Depress the bottom “Basket Levelling” and simultaneously depress the function key “Cage rotation
right” (the working cage moves upwards - cage up) or “Cage rotation left” (the working cage moves
downwards - cage down) until you have corrected the level of the basket
