AVANTI Service Lift for Wind Turbines
3.1 Purpose
The service lift purpose is to transport persons plus
their tools and equipment to the most convenient
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 techni-
cians, 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.
3.2 Scope
This manual contains instructions for one
version of the Dolphin lift:
• Dolphin A-V164 CE version.
An EC type-examination by a Notified Body
according to the Machinery Directive
2006/42/EC was performed
The product details are described along this manual.
The product consists of:
• A service lift, which is formed by: a cabin, a
traction system, a fall arrest device, a control
system, and safety devices.
• A guiding system along the tower, which is
formed by: a pair of steel guiding wire ropes, wire
fixes attached to the tower and roller wire guides
on the service lift.
3.3 Exclusions
The service lift shall not be used outdoor or in
potentially explosive atmospheres. The service lift is
not designed to carry a person on its top.
Unless otherwise agreed with Avanti, the wind
turbine manufacturer is responsible of integrating the
service lift and ensuring compliance with the
essential health and safety requirements as stated on
the 2006/42/EC Machinery Directive and the

3.15.1 Full sliding door
Main access to the cabin is done through the full
sliding door installed on the front. The full sliding
door opening dimensions are 2100 x 570 mm. It
features a guard locking system that:
• Prevents service lift to travel if the door is
open. This opening condition is monitored by
the guard locking switch.
• Permits door to be opened only when
service lift is levelled with a platform. This
levelling condition is monitored by the plat-
form level switch which is triggered by the
safe zone plates located in each tower
platform level.
It is possible to manually release guard
locking system in order to open main door
between platforms for maintenance tasks or
installation of WTG parts.

User’s Manual
3.19 Manual descent system
The service lift is provided with a lever allowing
manual release of the electromagnetic motor brake.
Once the motor brake is released, the service lift
descends with a controlled speed limited by a
centrifugal brake installed between the motor shaft
and the gear box. The manual descent buzzer will
sound while the service lift descends.
3.20 Fall arrest device
The service lift is equipped with a fall arrest device
which will be triggered in case of an overspeed
condition. The speed of the safety wire rope passing
through the device is continuously monitored, and the
jaws are automatically closed in the event of sudden
excessive speed.
This device protects the service lift against traction
wire rope breakages or traction system failures. The
fall arrest device can also be engaged or disengaged
manually by acting directly on the fall arrest device
levers.
- A foldable step is provided for access to the fall
arrest device levers. The user must observe all safety
precautions and check that the lift doors are closed
before climbing on it.
- To engage the fall arrest device: Turn the stop
lever counter clockwise.
- To release the fall arrest device: Turn the release
lever clockwise.

3.21 Overload limiter
A lifting force limiter is built into the wire rope
traction system and will prevent upward travel
in the event of overload. In case of overload,
the lift’s upward travel will be blocked, and a
buzzer will sound in the main control box. The
buzzer will stop only when the cause of the
overload has been removed.
• Reduce the load to below the overload limit.
3.22 Warning light
A set of warning lights is mounted on the top
and at the base of the lift. The flashes warn that
the lift is moving.
3.23 Acoustic buzzer
An optional audible signal can be installed with
the same warning function.
3.24 Anchor points
The service lift is equipped with two anchor
points inside the cabin. During operation
personnel shall hook themselves up to the
anchor points inside the cabin. In case of need
of evacuation, the evacuation procedure must
be observed.
There is an external anchor point 1) outside the
cabin to facilitate the evacuation and rescue
operations.
3.25 Internal light
The service lift is equipped with a light inside the
cabin. The light is on when the lift is powered,
and it is also battery packed in order to
illuminate the inside of the cabin in case of a
power failure (once charged).
3.26 Control cable management
3.26.1 Travelling cable
The travelling cable pulley straightens the cable
at all possible positions of the service lift. The
travelling cable pulley is mandatory for send/call
configuration.
The travelling cable pulley has two arms at-
tached to the guiding wire ropes. This way, the
guiding of the pulley improves.
On entering and starting the lift, the buzzer
may sound briefly. This is due to temporary
load peaks occurring as the lift takes off.
The control box is designed not to activate
the buzzer or stop the lift because of peak
loads caused by the cabin swinging.
Attempting to run an overloaded lift is
prohibited!
Performing a manual descent in case of
an overloaded lift is prohibited!

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:
