AVANTI Service Lift for Wind Turbines
2.1 Tower top
Wire lengths depend on the tower height and
should be specified when ordering. The coils are
marked with their length; check for accuracy prior
to mounting. Do not pull wire over any edges.
Uncoil correctly (Fig. 5a).
Warning!
Do not pull wire over edges.
Important!
Place all wire coils on the top platform
when tower is raised or use the tower
mounting crane to place the wires on the
top platform before nacelle is mounted. (It
may also be possible to use the internal
tower crane to hoist wires).
1) Mount the Ø12 mm guide wire and the Ø8 mm
drive and safety wires using the shackles
supplied for the suspension beam at the top of
the tower, with the guide wire outermost on
either side. (Measures: See Fig. 6 and dimen-
sions page 45).
2) Fit the nuts and bolts. Lock with cotters.
3) Fit the top stop disc on the suspension wire
leaving at least 200mm between disc and
shackle (See Fig. 5).
4) Feed all wires to the bottom of the tower (See
Fig. 5).
IMPORTANT!
All wires are evenly uncoiled
as shown in Fig. 5a to prevent
looping.
