anchor points inside the cabin, in order to prevent falling
risks. In case of need of evacuation, the evacuation
procedure will be followed.
3.6.21 Rescue pendant control
1)
Rescue pendant control is only mandatory if rescue
route of service lift can be somehow blocked. A blocked
rescue route is an event where:
• A person is unconscious inside the service lift,
blocking the bottom hatch,
• the rescuer is below service lift, and
• the service lift is stopped halfway through a platform
hole, blocking rescue route since platform has no
extra hatch.
There shall be one rescue pendant control per
WTG; and it shall be stored in the WTG
bottom platform. A clearly visible sign shall
indicate its exact location.
Note
1)
: In case of send or send/call configura-
tion, the rescue pendant control will not be
available.
It features three buttons: UP, DOWN and emergency
stop button. When necessary, pendant control is
plugged to cabin bottom socket. It has a 4 m long cable
that permits service lift to be powered up/down that
same distance. When plugged, pendant control does
not override any safety switch. If any of them is trig-
gered, no running will be possible; including the ob-
struction device switches. Therefore, there is no risk of
moving service lift hitting rescuer. Pendant control
overrides cabin control box, and service control box if
installed.
