rope, preventing loss of key.
Optionally, the platform fences can be equipped
with an electrical switch monitoring system, that
disables control of the elevator in case one platform
fence is open, which is composed by a manual
actuated mechanical lock connected to switch
cutting power to lift when it is opened, or with a
guardlocking system keeping the door locked while
the service lift is not at the platform. The door is
unlocked when the service lift is at the platform with
the lift detection switch activated. The ready light is
ON when the door is closed.
During emergency use, for example, power cut, need
of evacuation or rescue, the door guard locking
switch can be unlocked by acting the mechanical

while travelling.
3.6.11 Bottom hatches
Bottom hatches can be opened from both sides,
thus allowing egress and ingress from underneath.
Bottom cabin hatch opens inwards, and bottom
obstruction device hatch opens outwards.
Each of them has a safety switch that interrupts
control when hatch is opened.
Once top hatches and ladder access door are open,
clear area is at least 500 x 500 mm, and ladder
becomes totally accessible.
3.6.12 Top hatch
Top hatch can be opened from both sides, thus
allowing egress and ingress from above.
It has a safety switch that interrupts control when
hatch is opened.
Top obstruction device hatch opens outwards.
Once top hatches and ladder access door are open,
clear area is at least 500 x 500 mm, and ladder
becomes totally accessible.
Direct evacuation to ladder is possible at
any position along the WTG.
3.6.13 Bottom obstruction device
Bottom obstruction device interrupts descent if:
• It encounters an obstacle.
• It reaches the bottom platform.
Ascent will still be possible, for instance to remove
the obstacle. In order to put the service lift on the
ground, the contact plate functionality can be
bypassed with the override bottom obstruction
device switch located on the cabin control box. To
do so, turn the override bottom obstruction switch
key while pressing the down button.
Release the DOWN button as soon as the
rubber bumpers hit the floor. Otherwise
the service lift or the installation may get
damaged.

3.6.21 Rescue pendant control
Rescue pendant control is only mandatory if rescue
route of service lift can be somehow blocked. A blocked
rescue route is an event where:
• A person is unconscious inside the service lift,
blocking the bottom hatch,
• the rescuer is below service lift, and
• the service lift is stopped halfway through a platform
hole, blocking rescue route since platform has no
extra hatch.
There shall be one rescue pendant control per
WTG; and it shall be stored in the WTG
bottom platform. A clearly visible sign shall
indicate its exact location.

Warning buzzer
3.6.20 Anchor points
The service lift features two anchor points inside the
cabin.
Each anchor point may only be used by one
STOP
user simultaneously.
During operation users must hook themselves up to the
anchor points inside the cabin, in order to prevent falling
risks. In case of need of evacuation, the evacuation
procedure will be followed.
Note 1): In case of send or send/call configuration, the rescue pendant control will not be
available.
It features three buttons: UP, DOWN and emergency
stop button. When necessary, pendant control is
plugged to cabin bottom socket. It has a 4 m long cable
that permits service lift to be powered up/down that
same distance. When plugged, pendant control does
not override any safety switch. If any of them is triggered, no running will be possible; including the obstruction device switches. Therefore, there is no risk of
moving service lift hitting rescuer. Pendant control
overrides cabin control box, and service control box if
installed.

installation/maintenance tasks below the suspended
cabin. T his kit i s located o n th e cabin’s top.
It consists in a M14 screwed rod, that must be inserted
through a hole of the top rollers assembly and along a
rung of the guiding ladder, and finally blocked with a
M14 nut.

4.8 Overload limiter
!
!
a) In case of an overload, the lift’s upward travel
should be blocked (L95 versions), and a buzzer should
sound in the connection cabinet.
Attempting to run in an overloaded lift is prohibited!
STOP
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 (L95 version).
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 an a certified
technician adjust the overload limiter (Refer to
“Regulation of overload limiter” Appendix in
Installation and Maintenance Manual).
4.10 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”.
4.9 Manual descent
If a power failure or an operation fault etc. interrupts the
hoist, a manual descent is possible from inside the
cabin.
Brake release lever in L95
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 checked
by an expert
Pull to UNLOCK (Black) Pull to LOCK (Red)
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.

ppendix B: Stomp-test Instruction
A
Supplementary way to inspect the ASL during Daily Inspection before Operation
Purpose 2. Test Step
This instruction is a supplementary part of the Daily Lift
Checking to be used by authorized users and Certified
technicians. The information describes a recommended
and supplementary way of how to check the over speed
triggering and arresting function in the Avanti Safety Fall
Arrest Device model ASL. Second, the test also
documents that the Safety Brake maintains its grip on
the Safety Wire after engagement. This extra testing we
name the “Stomp-test”.
This stomp-test-method is supplementary to the given
daily obligation in your manual explaining “to descend
the lift, manually engage the FAD (Fall Arrest Device),
verification by short no-powerdescent, unloading the
FAD again by ascending and observing centrifugal weigh
unit through the window during lift use”. With the
“Stomp-test” we test the ability of the FAD to trigger in
case of over speed and arrest the load.
Tools: None
Measurement Equipment: None
Validity
It is applicable for testing the installed Safety Fall Arrest
Device (ASL) on-site. The test must only be performed by
trained users/Certified technicians and always with
respect of all the relevant safety regulations.
Cautions
Be aware that the instruction only explains the steps of
how to execute the “Stomp test” in the lift installation; it
doesn’t guide any safety precautions and the necessary
use of safety equipment.
With the cabin in “parked” position app. 3 m/10 ft. above
the bottom landing floor, the user starts descending by
electrical power using the push down button. When the
cabin starts descending the user executes a hard stomp
with one foot in the cabin floor – The hard stomp is
executed by lifting one foot, so the lower leg is positioned
with a knee angle of 90 degrees – Then immediately after
the foot is stomped in the cabin floor -
-The user must make sure to have a solid footing during
the foot stomp!
The foot stomp should engage the ASL and arrest the
electrical descent of the cabin, the red light (if existing in
the control box) should turn “on” and the cabin load
should be hanging on the FAD/Safety Wire.
If the ASL doesn’t arrest at the first trial, then
re-establish the cabin in the position described in the
preparation part mentioned above and execute the
“Step” once again stomping a little harder.
3. Test Result
If the ASL activates properly after the stomp, the ASL will
now hold the cabin on the Safety Wire.
In order to ensure important maintaining grip by the
Safety Brake, the user then activates the manual descent
function and result shall be a Safety Fall Arrest Device
ASL holding the cabin fixed on the Safety Wire
(manual descending is not possible).
- If the activated ASL fixes the cabin on the Safety Wire
while manual descent is activated, the Safety Fall Arrest
Device (ASL) is in good and operational condition.
Therefore, Avanti strongly recommends you to read and
understand what the physical work steps in the “Stomptest” are, and then execute your own Risk and Hazard
Assessment according to the valid safety working
procedures in your own organisation before starting the
test.
1. Test Preparation
The cabin (with 1 person inside) is ascended with a
service lift user inside, and the cabin bottom is
positioned (“parked”) in a height of app. 3 m/10 ft. above
the bottom landing floor platform.
34
In order to release the activated ASL push the ascent
button up a little before releasing the ASL by the
unlocking handle.
- If the ASL can´t activate after first or second
“Stomp-test”, or can´t fix the cabin in activated position
- User must immediately bring the cabin down and
park it at the bottom landing platform floor.
- Lock Out the installation from use and contact Avanti
for further approach!
- Document the execution of the above described
procedure in the Daily Inspection Log Appendix.
Any doubts regarding above instruction, please do not
hesitate to contact Avanti’s local representative for help.
