4. Description of equipment
4.1 Purpose
The service lift described in this User’s Manual
serves the following purposes:
- transportation of staff and material inside wind
turbine systems, lattice towers for wind turbines,
and telecommunication towers.
- transportation for mounting, inspection and
repairs.
The service lift may be used to transport two
persons plus their tools and equipment to the
most convenient height for performing work on the
tower.
The service lift is designed for permanent installa-
tion in one specific tower.
The lift is not designed for use
- in silos,
- at drilling sites,
- as a permanently installed facade lift,
- as a crane lift,
- in environments with explosion hazards.
4.2 Function
The service lift uses a traction hoist for ascending
and descending on a wire secured to the building.
Two safety brake safety gripping devices secure
the service lift to a separate safety wire.
Upward and downward travel is controlled from
inside the service lift in manual mode, from the
remote control transmitter in remote mode
(optional), or from the outside in the automatic
mode (optional).
A lifting force limiter prevents upward travel in the
event of an overload of the traction hoist.
Two guide wires on either side of the service lift
prevent the lift from swivelling/tilting.

4.5 Accesories
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:
4.5.1 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.
4.5.2 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.
