Adjustment of the overload controller (load cell)
WARNING!
Usually this device does need to be adjusted unless the device itself is replaced. The equipment
necessary for the replacement and adjustment of this component is such that these operations
should be carried out by skilled personnel.
AS THIS OPERATION IS VERY IMPORTANT IT IS TO BE CARRIED OUT BY SKILLED
TECHNICIANS ONLY.
The AIRO self-propelled articulated boom aerial platforms are
equipped with a sophisticated overload controller.
Normally the overload controller does not require any
adjustments, since it is calibrated in the factory before the
machine is delivered.
This device checks the load on the platform and:
▪
disables all movements if platform is overloaded by 20%
compared to the nominal load (drive and steering disabled
with platform lifted);
▪
with platform in transport position and overloaded by 20%
compared to the nominal load, only lifting is disabled;
▪
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.
Check operation at least once a year.
The overload controller consists of:
▪
deformation transducer ( A );
▪ electronic board ( B ) for the system calibration located inside
the platform control panel.
Operation check of the overload controller:
▪ when platform is completely lowered, load a charge evenly
distributed equal to the normal load allowed by the platform
(see paragraph “Technical features”). In this condition all
operations should be possible both on platform control panel
and ground control panel.
