7.3.8 Platform overload controller operation check
The AIRO self-propelled aerial platforms, X series, are equipped with a sophisticated platform overload controller.
Normally the overload controller does not require any adjustment,
since it is calibrated in the factory before the machine is delivered.
This device checks the load on the platform and:
 it disables all movements if the platform is lifted and
overloaded by 20% approx. compared to the nominal load
 with platform in transport position and overloaded by 20%
compared to the nominal load, it disables lifting only
 it warns the user of the overload condition by means of the
platform audible alarm and warning light
 by removing the exceeding load, the machine can be
operated again.
The overload controller consists of:

Deformation transducer (A) (load cell)

Electronic board (C) for the device calibration located inside
the box on the platform
Operation check of the overload controller:
 When platform is completely lowered and with extension deck
retracted, load a charge evenly distributed equal to the max.
nominal load allowed by the platform (paragraph “Technical
features”). In this condition all operations should be possible
both from platform and ground control panel.
 With platform completely lowered, add to the nominal load an
overload of 20% of the nominal load and carry out the lifting
operation. In this condition the red alarm light and the audible
alarm turn on.
If the platform is at a height from the ground higher than that
indicated in chapter “
Technical features ”, the alarm condition
locks the machine completely. To operate the machine again,
remove the excessive load.
7-9: Overload controller
Check operation at least once a year.
The system needs calibration:

in case of replacement of one of the items composing the system
 when, following an excessive overload, even after removing the excessive load, the danger condition is reported anyway.
