DANGER
IT IS ESSENTIAL TO COMPLY WITH
THE
ALARM SIGNAL AND TO
ESTABLISH A MORE STABLE
CONFIGURATION.
IN CASE OF THE MACHINE TIPPING
OVER, THERE IS A RISK OF SERIOUS,
EVEN FATAL INJURY.
3.3. SAFETY DEVICE AND ALARMS
3.3.1 EMERGENCY STOP
The machine is fitted with 2 emergency stop buttons:
- One on the upper electrical box.
- One on the lower electrical box.
Pushing one of these buttons cuts off the electric feed supply of the aerial work platform.
3.3.2 BUZZER
The buzzer is situated on the lower electrical box. It is activated by the detection of one of the
safety devices and by the push button situated in the upper electrical box.
3.3.3 INDICATOR LIGHTS
The light indicators are situated on the upper electrical box. Each one has an important meaning
that the operator should take into account, for these indicators are connected to the safety
devices of the machine.
3.3.4 SLOPE DETECTOR
3.3.5 CHAIN SLACK DETECTORS
The machine is fitted with a chain slack detector safety system. The
lowering movement of the mast is stopped as soon as an obstacle
prevents the mast from lowering correctly – cages placed on an
obstacle, poor adjustment of rollers, broken chains, etc...
As soon as the risk situation is detected, lowering of the mast
is stopped. The red indicator light of the alarm corresponding
to the chain slack situated on the upper electrical box, lights up
and the buzzer rings.
The operator is warned of the danger and
must before any operation analyze where the source of detection of
the chain slack comes from. He must then raise the mast to retighten
the chains. If the phenomenon persists, do not continue, and
immediately alert the appropriate personnel to assist the occupants
of the aerial work platform.
In work position, when
the platform is inclined
at 2° compared to
horizontal, the detector
triggers the buzzer.
The
indicator light
corresponding to the
incline of the machine
situated on the upper
electrical box lights up.
Triggering of the alarm signals indicates that the aerial work platform has reached its stability
limits. No function must be activated except those needed to bring the platform back to a more
stable configuration, in other words to lower the mast and retract the arm.
