AVANTI Service Lift for Wind Turbines
The service lift purpose is to transport persons
plus their tools and equipment to the most con-
venient height for performing work in wind turbine
generators (WTG).
Its use is limited to authorized users.
The access to the WTG and consequently to the
service lift is controlled and forbidden to public
access.
The service lift is used primarily to transport
technicians, their tools and spare parts from the
bottom platform (or lowest accessible point) to the
top platform (or highest accessible point).
It is also used to access intermediate platforms
where inspection and service of WTG connecting
bolts and other equipment is made.
5.2 Function
The service lift uses a traction hoist to ascend and
descend a wire rope suspended from a beam
within the wind turbine along a defined travel path.
A fall arrest device is attached to the service lift and
ascends and descends with it on a second
suspended wire rope, called the safety wire rope.
Ascent and descent of the service lift is controlled
from within the service lift via a manual mode or
from outside the service lift in an automatic send
mode.
An overload limiter prevents ascent of the service
lift in the event of an overload of the traction hoist.
Two tensioned wire ropes act as guiding means
along the travel path of the service lift.
5.3 Service lift models
This User’s Manual and Installation Manual
describe the following models:
• SHARK L AECO sliding door with 533 Lbs
(240kg) lifting capacity, AECO control box,
traveling cable (optional) and slack rope sensor.
5.4 Temperature
Operating temperature
5ºF to +140ºF (-15ºC to +60ºC).
Survival temperature
-13ºF to +176ºF (-25ºC to +80ºC).
Low temperature kit is also available. Operational
temperature for low temperature kit
-13ºF to +104ºF (-25ºC to +40ºC).
5.5 Accessories
In order to fulfil the essential health and safety
requirements from the regulations the design of
the wind turbine and its components shall comple-
ment the safety systems supplied on the service
lift making the ensemble safe as a whole.
A detailed evaluation of compliance to the EHSR
and a risk assessment shall be completed. Avanti
shall verify the compliance to such requirements
prior to installation. Systems that may be consid-
ered to complement the service lifts are:
5.5.1 Fences & guards
The service lift hole must be adequately protected
to prevent people from falling or being injured by
the movement of the service lift. The fences and
guards design shall comply with the relevant
standards and local regulations.
5.5.2 Safety system for landing access doors
The service lift hole must be adequately protected
to prevent risk of falling. When the service lift is not
at the landing, access doors shall not be able to
open. Such function may be achieved by using
interlock systems on access doors linked to the
position of the service lift.

the side panels inside the lift (Fig. 8).
5.7.4 Automatic operation switch
A switch situated inside the pendant control
holder. It prevents the lift from being controlled
from the inside when the control is in automatic
mode.
5.7.5 Overload limiter
The overload limiter is built into the wire rope
traction system and will prevent upward travel in
the event of an overload. A warning signal
(buzzer) is triggered which will stop only when the
cause of the overload has been removed.
Possible reasons for activation of the limiter:
- The service lift is overloaded or
- the service lift encounters an obstacle during
upward travel.
Operator intervention:
- Reduce the load to below the overload limit, or
- lower the lift until it is free of the obstacle and
remove the obstacle before using the lift again.
5.7.6 Fall arrest device
Service lifts for personnel transportation must be
equipped with a fall arrest device which will
prevent the load from falling.
Fall arrest device type ASL.The fall arrest devices
ASL are opened manually (Fig. 7).
The speed of the safety wire rope passing
through the device is continuously monitored,
and the jaws automatically close in the event of
sudden excessive speed.
This protects the service lift from
a) Traction wire rope breaks and
b) Hoist failures.
The fall arrest device can also be engaged
manually in an emergency by pressing the
Emergency stop button. The window is used to
monitor the function of the centrifugal force
mechanism during operation.
5.7.7 Yellow flash (optional)
An optional set of flashes can be mounted on the
top and at the base of the lift. The flashes indicate
when the lift is in movement (Fig 9a).
4.7.8 Emergency light (optional)
An emergency light can be installed to provide
illumination inside the lift with and without electric
supply. The operation modes can be selected
by means of a switch (Fig. 9b).

At the top of the cabin frame a top obstruction
detection device switch (works as a top limit stop
switch) will stop upward travel when activated (Fig. 11).
Downward travel will still be possible. A top stop bar
which activates the top obstruction detection device
switch is installed below the traction wire rope
attachment.
ATTENTION!
When the top obstruction detection
device switch is engaged, activate the
DOWN switch until the top obstruction
detection device switch is released.
5.7.12.2 EMERGENCY top limit switch
Deactivates control if the top obstruction detection
device switch fails (Fig. 11). Manual downward travel is
possible.
CAUTION!
Do not use the service lift until the top
limit stop switch fault has been rectified.
5.7.11.3 Bottom obstruction detection device
The bottom obstruction detection device switch (Fig.
12) stops downward travel if the service lift
encounters an obstacle or t o uches the ground.
Upward travel will be possible, for instance to remove
the obstacle. In order to put the service lift on the
ground, the contact plate’s operation can be bypassed
with the key switch in the control box.
5.7.11.4 Top obstruction detection device
The top obstruction detection device switch stops
upward travel in case the service lift:
- Type 1: encounters an obstacle.
- Type 2: the switch also works as a top limit stop
switch. A top stop end bar is installed bellow the
guiding wire rope attachment and activates the top
obstruction detection device switch.
Downward travel will be possible, for example, to
remove the obstacle.
5.8 Safety devices for fences with
doors (optional)
Safety devices for fences include devices to prevent
people from accessing the service lift area, unless the
service lift is safe to be accessed. The device also
guarantees that the service lift does not when the
protective fence doors are open. There are two types
of safety devices for fences:
5.8.1 Guard Locking System
The Guard Locking System uses a system of security
locking switches installed on the fences. Another
position switch detects the correct position of the
service lift on the protected platform. The service lift
cannot operate until all the protected fences are
closed and locked.

AVANTI Service Lift for Wind Turbines
The fences remain closed and locked until the service
lift is stopped and properly positioned on the platform,
actuating the position switch of the platform. In this
position, the guard locking can be unlocked while
pressing the green light button.
The interlock control box has a main switch. Turn the
switch to the OFF position to cut the power to the
service lift. The main switch must be set to OFF when
the lift is not in use, when leaving the wind turbine and
while the wind turbine is running. It must be set to OFF
before starting an electrical generator.
Consult the AVANTI Guard Locking System Manual
for further information.
5.8.2 Trapped-key Interlock System
The Trapped-key Interlock System uses a system of
security locks installed on the fences. These locks can
be opened by using a key placed into the lift.
The key also activates the On/Off general switch
placed into the service lift cabin. The key is linked to
the lift by means of a wire rope, and cannot be
detached from it except using cutting tools.
The key cannot be taken out from the On/Off general
switch in the lift, unless it is in Off position, and
therefore, the lift is stopped. In the same way, the key
cannot be taken out from the fence lock unless the
fence door is closed, and the door actuator is put into
the door lock.
The fences remain closed and locked until the service
lift is stopped on the platform, and the key is trans-
ferred from the lift cabin to the fence lock.
Consult the AVANTI Trapped-key Interlock System
Manual for further information.
5.9 Slack rope sensor
Installed on the top of the service lift, over the
traction hoist, when engaged it will remove power
from service lift. It detects slack traction wire rope.
5.10 Anchor points
