3.6 Safety devices
3.6.1 Top obstruction device
The top obstruction device is installed on the top of the
service lift.
The device fully covers top cabin face. The cover is
provided with a hatch in case of evacuation.
When top obstruction device is activated, service lift will
stop ascent as a consequence of one of the top
obstruction device switches triggered, this happens
when the lift encounters an obstacle. Descent will be
possible, for instance to remove the obstacle. The service
lift features three top obstruction device switches in order
to improve its sensitivity.
Optionally, top obstruction device could feature yellow
flexible side covers.

3.6.3 Bottom obstruction device
The bottom full plate obstruction device is installed on
the bottom of the service lift.
The device fully covers bottom cabin face. The cover is
provided with a hatch in case of evacuation.
When bottom obstruction device is activated, service lift
will stop descent as a consequence of one of the bottom
obstruction device switches being triggered, this
happens when the lift encounters an obstacle or touches
the ground. Ascent will be possible, for instance, to
remove the obstacle. The service lift features three
bottom obstruction device switches in order to improve
its sensitivity.
In order to put the service lift on the ground, the bottom
obstruction device functionality can be bypassed with the
bottom obstruction override switch in the user control
box. To do so, turn the bottom obstruction override
switch while pressing the DOWN button.
Optionally, bottom obstruction device could feature

3.6.4 Overload detection device
An overload detection device is built into the traction
hoist. In case of an overload, it will prevent up the
movement of the service lift (by interrupting control) and
a buzzer will sound until overload condition is eliminated.
The overload detection device adjustment procedure is
explained in the Installation and Maintenance Manual.
