AVANTI Service Lift for Wind Turbines
4.7 Overload limiter
a) In case of an overload, the lift’s upward travel
should be blocked, and a buzzer should sound
in the connection cabinet.
STOP
Attempting to run in an overloaded lift is
prohibited!
Performing a manual descent in case of an
overloaded lift is prohibited!
b) Remove enough of the load to make the
buzzer stop and enable upward travel.
!
On entering and starting the lift, the buzzer
may sound briefly. This is due to temporary
load peaks occurring as the lift takes off.
The overload limiter is designed not to activate
the buzzer or stop the lift because of peak loads
caused by the cabin swinging.
If the problem persists have a certified
technician adjust the overload limiter (Refer
to “Regulation of overload limiter” Appendix
in Installation and Maintenance Manual).
4.8 Manual descent
If a power failure or an operation fault etc.
interrupts the hoist, a manual descent is possible
from inside the cabin.
1. The lever is attached underneath the cabin top.
Turn it down.
2. Push the lever upwards the full way. The service
lift moves downwards. The built-in mechanical
overspeed limiter limits the pace of descent.
3. To stop, simply loosen the lever.
4. After manual descent, the system must be
5. checked by a certified tecnician.
STOP
During the manual descent, the doors,
window and hatches of the lift shall be kept
closed. Don not extend body parts outside
the cabin during travel.
!
During manual descent if the bottom
obstruction device hits an obstacle, the
brake release lever is mechanically
disengaged so the further descent is
disabled. The system is automatically reset
once the obstacle is removed.
4.9 Fall arrest device
To lock the fall arrest device in an emergency:
• Pull down the red handle.
If the fall arrest device engages, simply disengage
it from inside the cabin until the fall arrest device
is unlocked by:
• Pulling the black handle downwards.
• However, this is not possible if the safety wire rope
is under tension. If this is the case:
1. Remove the load on the safety wire rope by
pushing the UP button taking the lift upwards a
few centimetres.
2. Manually open the fall arrest device until the fall
arrest device is unlocked by:
• Pulling the black handle downwards.
In case of no power and the fall arrest device is
locked with the safety wire rope under tension
evacuate the lift according to the “Evacuation
guide”.
