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 certified technicians. 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 connect-
ing bolts and other equipment is made.
3.2 Scope
•
The Octopus service lift system consists of
the following subsystems:
•
Cabin.
•
Traction and fall arrest systems.
•
Guiding system.
•
Control, safety and power systems
(including an interlock system on platform
fence doors).
•
A rescue pendant control

1)
In case of send or send/call configuration,
the rescue pendant control will not be
available.
Each of the subsystems listed above and their
components are described in detail throughout
the document.
The system fully complies with essential health
and safety requirements of European Machinery
directive.
There are two different configurations for
working temperature ranges; in particular, there
is a standard configuration and a low
temperature configuration where traction
system and main control box components are
chosen specifically.
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.
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 applicable
harmonized standards following the
manufacturer recommendations.
This will require supply of interface components,
including but not limited to:
• Ladder system.
• Brackets for ladder sections.
• Platform fences with doors.
• Power supply protection.
The wind turbine manufacturer shall also
provide any additional relevant warning,
instruction and / or training specific to the
integration of the service lift necessary for its
safe and correct installation.
Tower manufacturer’s risk
assessment shall include a service
lift integration study.
