AVANTI Service Lift for Wind Turbines
8. What to do if the safety gripping device engages
If the safety brake engages simply disengage by
pushing down the lever (Fig. 16A) until it click.
However this is not possible if the service lift is
hanging on the wire - if so, see below.
DANGER!
In the event of lift wire breaks or hoist
fails, evacuate personnel from the
service lift.
The safety wire suspension and the attachment
between the safety brake and the service lift are
exposed to dynamic loads when a fall is blocked.
If the safety brake has locked and the service
lift is hanging on the wire, ascending is blocked.
Do as follows:
a) Remove the load on the safety wire by taking
the service lift upwards
– In the event of a power failure, operate the lift
manually as explained in section 7.2.
b) Manually open the safety brake by pressing
down the leaver (Fig. 16A) until it disengage. On
ground level perform test as specified in
section 5. e) of the Installation Manual section
and 5.6 of the User’s Manual before resuming
normal operation.
ATTENTION!
When the service lift has returned to
ground level, test the safety brake
function as specified in 5. e) of the
Installation Manual page 54 and 5.6 of
the User’s manual page 21.
CAUTION!
Replace any defective safety brake
components and return them for repair
to the manufacturer.
