User’s, Installation and Maintenance Manual
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 genera-
tors (WTG).
Its use is limited to authorised personnel by AVANTI
holding the relevant training certificates.
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.
3.2 Scope
The system consists of a rack and pinion service
lift guided along a metal ladder and the necessary
accessories allowing the connection to the tower
and providing the control and safety functions
described in the manual. The accessories include:
mast supports (ties to the tower brackets), rest
platforms, mechanical stops, safe zone plates,
control stations and other electrical equipment. It
also includes the hardware necessary to make the
connections, labels and warning signs.
The mast sections, their supports and related
accessories may be assembled to the tower in the
tower factory and supplied later on site for final
installation. The cabin is supplied pre-assembled
and may be supplied to the tower factory or on site
directly. Final assembly, adjustment, installation
and verification of the service lift shall be made on
site.
The installation of the service lift shall only be made
by AVANTI or by a company trained and authorised
by AVANTI.
The system, as defined on this scope, is part of
machinery falling under Annex IV, section 17 of the
European Machinery directive and meets the
essential health and safety requirements. A
declaration of conformity of the complete system
integrated in the wind tower can only be issued
after the system has been fully incorporated.
In case the necessary information for the evaluation
is not supplied to AVANTI, a declaration of incorpo-
ration shall be issued. The wind tower manufac-
turer is responsible for ensuring full compliance of
the system once integrated in the tower in such
case. To do so, the instructions and requirements
stated in this manual shall be observed.
3.3 Exclusions
The service lift must not be used outdoor or in
potentially explosive atmospheres.
The equipment listed below is specifically out of
the scope and is needed for the safe integration
and use of the service lift.
- Fences to protect users from falling through the
service lift hole at platforms. They shall at least
comply with EN 14122-3, have non-slip rails or
steps facilitating access to the lift at platforms and
have no doors.
- Interlock systems for platform fence doors or
hatches (when existing) preventing any movement
of the lift if the door or hatch are not closed and
locked.
- Emergency lighting along the tower and user
portable light / helmet light as cabin uses perfo-
rated sheet to allow tower light inside.
Tower manufacturer’s risk assessment shall
include a service lift integration study.
