AVANTI Service Lift for Wind Turbines
4.4.1 Bottom platform
1. Turn the main switch ON of the platform control box.
2. Close the bottom platform fence door.
3. Insert the trapped key inside the switch on the user
control box and turn it ON.
4. Close the service lift door.
5. Press the UP button using the send tool.
4.4.2 Top platform
1. Close the top fence door.
2. Insert the trapped key in the switch of the user control box
and turn it ON.
3. Close the service lift door.
4. Press the DOWN button.
4.5 Operation from the platform control
boxes
1. Turn the trapped key switch to ON.
2. Close the door of the cabin and of the platform fence.
3. Press and hold the UP or DOWN button to
ascend or descend the cabin.
4.4 and 4.5: When actuating UP or DOWN
buttons, response of cabin is delayed for 5
seconds while the warning lights are flashing
and an acoustic signal will sound,in order to
warn personnel in the surroundings that cabin
is going to move.
Transportation of people is forbidden if the
operation is controlled from a platform control
box.
Before closing the lift door, ensure that your
equipment (i.e.lanyards) do not get trapped/
tangled with the closing door and/or with
surrounding elements.
To prevent the lanyards from tangling
with surrounding elements, keep them
properly attached to your body harness.
To prevent the lanyards from tangling with the
moving service lift, do not get close to the
hoistway.
4.6 Fall arrest device
If the fall arrest device engages simply disengage it by
turning the “Unlock” lever clockwise until the
fall arrest device is unlocked.
However, this is not possible if the safety wire rope is
under tension. If this is the case:
1. Remove the load on the safety wire rope by pushing
the UP button ascending the service lift a few
centimetres.
2. Manually open the fall arrest device by turning the
“Unlock” lever clockwise until the fall arrest device is
unlocked. In case of power failure and the fall arrest
device is locked with the safety wire rope under
tension evacuate the lift according to the evacuation
procedure.
The safety wire rope and the attachment
between the fall arrest device and the service
lift are exposed to dynamic loads when a fall is
prevented. When the service lift has returned to
the bottom platform, test the fall arrest device
functionality. Replace any defective fall arrest
device components and return them for repair
to AVANTI.
4.7 Manual descent
In case of power failure, a manual descent without
power can be performed. To do so:
1. Verify that the fall arrest device is unlocked.
2. Check that there are no obstacles or persons in
the travel zone.
3. Take the manual descent actuator from its holder
and insert it on the lever extension tube.
4. Push the manual descent actuator upwards. The
service lift will start descent and a buzzer will sound.
5. To stop the manual descent, stop pushing upwards.
During the manual descent, the door and
hatches of the lift shall be kept closed.
Use the walkie-talkie to report about the manual
descent.
During the manual descent, stop the service lift
just before reaching the bottom platform floor.
This way, the bottom obstruction device will not
get damaged.
4.8 After use instructions
1. Bring the service lift all the way down, until the
bottom obstruction device stops the cabin.
2. When leaving the wind turbine, turn the main
switch in the bottom platform box to the OFF
position to cut the power to the service lift.
Before leaving the WTG, ensure the lift is
positioned in the bottom platform.
Risk of material damage. Do not place the
service lift on the rubber bumpers.
The power cable and traction/safety wire
ropes could get tangled in WTG internals.
