DANGER
DO NOT ACTIVATE THE EMERGENCY
STOP TO CUT THE ALARM AND
CONTINUE WORKING. UNLOAD THE
PLATFORM UNTIL THE ALARM STOPS.
5.2. LOAD CONTROL
When the permissible load on the work platform
is exceeded, the corresponding lights on the
control stations flash, an alarm sounds and all
the movements are stopped. The platform must
be partially discharged until the alarm stops.
If the overload was triggered by a collision with
an obstacle at a height, the platform may be
cleared using the auxiliary hydraulic group. This clearance procedure is strictly reserved for this
precise case.
1- Cut the diesel engine.
2- Use the auxiliary hydraulic group to make the appropriate clearance movement (See
Section 6.1.3
– Auxiliary hydraulic group). The telescope can only be lowered and
retracted.
3- Once the platform is cleared, restart the diesel engine and return the platform to low
position. Check that the platform or load control mechanism have not been damaged
before returning the machine into service.
-NOTE-
A cutout of all movements including those performed from the auxiliary group can be
configured in the system : Refer to §8.3.1 - Settings
5.3. CALIBRATION OF THE OVERLOAD PLATFORM SYSTEM
1. Put the machine on a firm and level surface; make sure the work
platform is horizontal.
2. Using the key switch select the upper or lower control panel
3. Check the maximum load allowed into the platform (
manufacturer’s
plate).
4. Remove all tools and accessories from the work platform.
5. Place a test weight equal to the maximum platform ca 10 kg
(240kg).
6. The overload light must flash and the alarm must sound.
If the alarm does not sound, slowly loosen the load spring adjustment
nut in counterclockwise direction with 17mm wrenches until the alarm
stops.
7. From the ground, lift manually the platform by about 5cm, the alarm
must stop.
