AVANTI Service Lift for Wind Turbines
5. Inspection before initial use
An officially recognised expert must:
a) Inspect the lift as specified in section 12.1 of
the User’s Manual.
b) Carry out a test run with the maximum rated
load.
c) Overload test: The test load depends on the lift
motor. Load the cabin as follows:
Motor L402P: load kg 320 (125% of lifting
capacity + weight of power cable). Motor
L502P: load kg 420. When an attempt is made
to start the lift, the platform should stop, and
the buzzer in the connection cabinet should
sound.
– If not, see Appendix A: “Adjusting instructions
for overload limiter” on page 55.
d) The guide, drive and safety wires as well as the
top and bottom wire fastenings must be tested
at full length as part of the initial test run.
e) Testing of the safety brake safety gripping
device:
Important!
Before testing, the tightening spring be-
neath the access platform must be re-
moved. Remember to secure it again after
testing (Fig. 13a or 13b pages
50-51) !
DANGER!
If the safety brake safety gripping
device is engaged, it must not be
possible to pull the safety wire up-
wards!
1) Engage the safety brake by pressing the
stop button – the handle should jump to the
“ON” position (Fig. 15).
Should it nevertheless be possible to pull the
safety wire upwards, the safety brake must
be replaced and sent to the supplier for
testing.
2) Reopen the safety brake by pressing down
on the lever. On top of the lift, pull up the
safety wire with a quick jerk – the safety
brake should now engage automatically; if it
does not, replace it and return to the
supplier for testing.
f) If guide wires are mounted using the tripod,
tighten the tripod wire locking device.
The results from this test must be
recorded in writing and saved for later
reference (Appendix B page 59).
