AVANTI Service Lift for Wind Turbines
Tightening torque required: 6Nm for 8mm traction
rope grip plus half-bushings, 20 Nm for 12mm
guiding wire rope grip. See Annex B.
2 pieces protection bushing included in the top limit
device set must be installed only in the 8mm wire
rope. To install it, just put the 2 pieces together
around the wire rope in the position where the
wirelock are going to be fixed.
Apply the torques indicated with lubricated screws
(not dry). Only use lubricant type ‘Molykote G-Rapid
Plus’ or similar which ensures no damage to screws.
2) Uncoil wire ropes correctly (Fig. 3).
All wire ropes are evenly uncoiled as shown in
Fig 3 to prevent looping and kinks.
Ensure that no obstacles are in the way of the
service lift. Do not pull wire over edges.
3) The wires must be uncoiled carefully as descend-
ing them one by one to the bottom of the tower in a
controlled way.
Once the wires are securely attached to the top
suspension beam, take the tip of the first guiding
wire, pass it through its corresponding hole in the
yaw platform and manually lower it in a controlled
way while another technician in direct communica-
tion guide you from the ladder and help avoiding
obstacles if necessary.
When the first guiding wire is fully installed under
bottom platform (see section 3.3.4), repeat the
process with the other one.
Then descend successively the traction and the
safety wires and install them according to sections
3.5 and 3.6.
When descending wires keep the lowering
speed and direction always under control to
prevent it from causing damage to or becom-
ing blocked in one of the tower’s components.

system’s wire rope inlet opening.
3. Push the UP button on the cabin
operation control (manual control from
inside the cabin) and feed wire rope
through until the traction system starts
pulling. Ensure that the wire rope
can exit without obstruction!
4. Continue feeding the wire rope under-
neath (round) the back guide wheel and
over the front guide wheel.
5. Let the traction wire rope pass through
until it is slightly tightened.
6. Feed wire rope through cabin bushings
and then through the platform floor
towards the basement.

Installation Manual
3.6 Securing the traction
and safety wire rope
The traction wire rope is fastened as described in
point 3.6.1 below and the safety wire rope is
fastened as shown in point 3.6.2.
Apply the torques indicated with lubricated
screws (not dry). Only use lubricant type
‘Molykote G-Rapid Plus’ or similar which
ensures no damage to screws.
3.6.1 Traction wire rope counterweight
An 11kg (25,25 lb) weight is mounted approximately
200mm (7,87 in) below the bottom platform on
the traction wire rope hold by means of two wire
rope grips torqued to 6 Nm (see Annex B).
Excess of wire rope is coiled with at least three
strips (see fig. 14a and 14b).
3.6.2 Safety wire rope push spring
Steps to install the push spring are detailed
below (see fig 15):
1. Feed the safety wire rope through the bottom
platform hole.
2. Ascend the service lift 50 cm.
3. Activate the fall arrest device.
4. Perform manual descent so that the weight of the
service lift is transmitted to the safety wire rope.
5. Compress the spring to 40 mm and fix with cable
ties.
6. Feed the safety wire rope through the compressed
spring.
7. Pull the safety wire rope downwards by hand as
much as possible.
8. Place and fasten the two wire rope grips (torqued
to 6Nm according to Annex B).
9. Cut the cable ties so that the spring decompresses
to 55 mm.
Optionally, the push
spring can be
replaced by two or
three 11 kg
counterweights
(depending on the
configuration) as
the used on the
traction wire rope.
3.6.3 Traction and safety wire ropes grounding
To allow the rotation of the traction wire rope and
provide the proper grounding of it, a “rotating
grounding unit” may be used. See picture below:
To install the rotating ground unit: prior to counter-
weight installation, insert the traction wire rope
through the unit and fix it in a suitable position below
the lower bracket by means of the two M8 screws in
the lower part of the unit. Torque required is 4Nm
(see Annex B).
The earthing cable is then
attached to the unit by
another M8 screw
located on the top of it.
Torque value is not
specified for this
screw, just ‘snug-tight’
required.
The safety wire rope‘s lower
end can be grounded by
simply connecting the
earthing cable to the wire
by means of an appropriate
bracket, similarly to the
top end of the wire ropes.
See picture to the right:
Ensure that counter-
weight and wire rope
coils can rotate freely.
Before fastening
the safety wire
rope carry out
the fall arrest
device test.

3.7 Wire rope fix alignment
Having mounted the service lift, the wire ropes,
and the power cable, adjust the wire rope fix
alignment during the first run.
The wirefixes are made of two parts. Theses
two-piece concept allows the wirefix to be installed
at any moment, without having to introduce it
through the bottom end of the wire rope but just
putting the 2 pieces together around the wire rope.
There are 2 installation windows located on
the rear of the service lift. These shall only be
used during installation and maintenance
tasks.
In order to avoid risks, turn the power supply
off from the service lift before opening the 2
installation windows. Do not turn the power
supply back on until the windows are closed.
Besides, in order to install/adjust wirefixes, the
lift’s door has to be opened. People have to
be always attached to the anchor point when
using the lift. Confirm you are properly
secured before opening the door.

The final position of the wire rope fixes shall be
adjusted with the help of the installation tool
(item number AT00011211, see Fig. 17) and
following the procedure below. The distance
between wirefixes is 1220 ± 2 mm.
1. Put the installation tool inside the lift and
ascend to the installation position of the first
pair of wirefixes.
2. Turn the operation selector to 0FF position,
push emergency stop switch, and then open
the two installation windows.
3. Install the first pair of wire fixes to the tower
structure using the holes provided.
4. Attach the left end of the installation tool to
the left guiding wire rope (see Fig. 18).
5. Attach the right end of the installation tool to
the right guiding wire rope (see Fig. 19).
6. Slide the installation tool downwards until it
contacts the wire rope fixes (see Fig. 20).
