User’s, Installation and Maintenance Manual
Before using the service lift, if it has not been used for a
long period of time:
• Clean all the parts of the service lift of accumulated
dust.
• Grease the shafts, pinions and rack.
11. Installation
11.1 WTG requirements
The following information is necessary for the correct
integration of the service lift inside a wind turbine tower.
11.1.1 Height and angle
The service lift can be installed on towers up to 150 m
high, and with a maximum inclination angle to the ladder
axis of ±2º and of ±0,5º for every 3 m of ladder.
11.1.2 Lift holes at platforms and air gap to tower parts
The service lift must have an air gap of at least 25 mm
around it along the tower to avoid collision with tower
components and to avoid finger trapping. The wind
tower manufacturer must verify this as part of the
integration process not only in the static position but
also considering possible movement of components
inside the tower as a consequence of the tower sway.

10. Storage
The storage conditions shall be agreed with customer. If
special storage requirements are needed, customer
shall specify them to AVANTI prior to delivery. The
following conditions shall be considered.
10.1 Before installation of service lift
on WTG tower section
Keep the service lift in its original packaging until it is
mounted on the WTG tower section.
Avoid direct contact of package with floor by placing a
pallet under it. Position the pallet on a stable ground.
Store the service lift in a dry place and protected from
rain (i.e. in roofed areas). In corrosive environments (i.e.
near the sea or in foggy places) store indoors.
Store in a clean and ventilated place, free of negative
influences of chemical and water vapours or other
corrosive substances.
Store between -30ºC and 80ºC (survival temperature). If
possible, avoid sudden temperature changes.
Handle the service lift with care and store in a safe place
in order to avoid unintended damages.
Do not stack.
Should any of these conditions not be maintained, the
service lift could be spoilt with dirt or other substances,
which could start corrosion before even the service lift is
put into operation.
Store the package so that its labelling is clearly readable.
10.2 After installation of service lift on
WTG tower section
After installing the service lift in the WTG tower section,
confirm that the service lift is properly attached to the
ladder (i.e. pinions are engaged with rack, and rollers
and anti-derailment brackets are mounted).
Close top and bottom holes of WTG tower sections with
covers to prevent water entry.
10.3 During WTG tower erection
During the erection of the WTG tower sections, and
while there is risk of rain entry, protect the service lift
with wrapping film to prevent water entry.
If WTG tower erection is left uncompleted, close the top
hole of the WTG tower section with a cover.
In case that the inside of the WTG tower sections is
washed, protect the service lift with wrapping film to
prevent water entry.
10.4 After service lift is put into service
If the service lift is not going to be used for a long period
of time:
• Clean all the parts of the service lift using
non-abrasive brushes.
• Clean the pinions and racks thoroughly and grease
them to prevent corrosion.
