3.2 Cabin
3.2.1 Service lift doors
3.2.1.1 Main service lift door
Two configurations are available for the main ingress
and egress of the service lift with the following door
types:
– Full sliding door (on the right or on the left side).
– Optionally two full sliding doors (on the right and on
the left side).
It features a guard locking system that:
• Prevents service lift to travel if the door is open. This
opening condition is monitored by the guard locking
switch (S19.3).
• Permits door to be opened only when service lift is
levelled with a platform. This levelling condition is
monitored by the platform level switch (S18) which is
triggered by the platform level activation plates.
Optionally, this levelling condition could be monitored
by a photoelectric sensor which is activated by
reflective plates or tapes located in each platform level.
Figure 5: Platform level switch
It is possible to manually release guard locking system
in order to open main door between platforms for
maintenance tasks or installation of WTG parts.
External manual release of
guard locking
Internal manual release of

Figure 6: Manual release of guard locking system
Related to the optional configuration of 2 sliding doors,
there would be 2 possible scenarios:
–A) The first door (D1) only could be opened
when Platform level detection switch (S18) +
Bottom or Top obstruction device switch (S2 or S1)
are activated, while the second sliding door (D2)
would be locked. The second sliding door (D2)
only could be opened when Platform level
detection switch (S18) is activated, while the first
sliding door (D1) would be locked.
–B) The cabin features 2 platform level
detection switches (S18.1 and S18.2). Depending
on the platform, the platform level activation plate is
located on the right side or on the left side, so only
one of the platform level detection switches
(S18.1 or S18.2) is activated, unlocking just the
related door (D1 or D2).

3.5.3 Rescue pendant control
Rescue pendant control is only mandatory if rescue
route of service lift can be somehow blocked and in
case of an external call control box is not installed at
the bottom platform. 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.
CAUTION
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.
Figure 17: Rescue pendant control
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.
NOTICE
See the Rescue guide placed next to the Rescue
pendant control on the bottom platform fence.
All the controls are hold to run.

3.6 Safety devices
3.6.1 Top obstruction device
The top obstruction device is installed on the top of the
service lift.
The device fully covers top cabin face. The cover is
provided with a hatch in case of evacuation.
When top obstruction device is activated, service lift will
stop ascent as a consequence of one of the top
obstruction device switches triggered, this happens
when the lift encounters an obstacle. Descent will be
possible, for instance to remove the obstacle. The service
lift features three top obstruction device switches in order
to improve its sensitivity.
Optionally, top obstruction device could feature yellow
flexible side covers.

3.6.3 Bottom obstruction device
The bottom full plate obstruction device is installed on
the bottom of the service lift.
The device fully covers bottom cabin face. The cover is
provided with a hatch in case of evacuation.
When bottom obstruction device is activated, service lift
will stop descent as a consequence of one of the bottom
obstruction device switches being triggered, this
happens when the lift encounters an obstacle or touches
the ground. Ascent will be possible, for instance, to
remove the obstacle. The service lift features three
bottom obstruction device switches in order to improve
its sensitivity.
In order to put the service lift on the ground, the bottom
obstruction device functionality can be bypassed with the
bottom obstruction override switch in the user control
box. To do so, turn the bottom obstruction override
switch while pressing the DOWN button.
Optionally, bottom obstruction device could feature
yellow flexible side covers.

3.6.4 Overload detection device
An overload detection device is built into the traction
hoist. In case of an overload, it will prevent up the
movement of the service lift (by interrupting control) and
a buzzer will sound until overload condition is eliminated.
The overload detection device adjustment procedure is
explained in the Installation and Maintenance Manual.
16
3.6.5 Warning light
An optional set of warning lights is mounted on the top and
at the base of the lift. The flashes warn that the lift is
moving.
3.6.6 Acoustic buzzer
An audible signal is installed with a warning function.
If the external buttons of the user control box or platform
control boxes are used, the operation will be delayed and
an acoustic warning emitted. This way, the persons next to
or inside the cabin are alerted of an inminent movement of
the service lift and can act accordingly. This same acoustic
buzzer sounds while the cabin is overloaded.
Manual descent buzzer sounds during all the descent when
user performs a manual descent.
3.7 Manual descent system
The service lift has a manual descent system that
can be used in the event of a power failure
emergency situation.
(See section 4.3.9 in Use of
service lift)
3.8 Guiding system
3.8.1 Guiding ladder
The service lift is guided by ladder. The guiding system
function is to safely guide the service lift along the ladder
stiles.
The guiding system consists of the guiding ladder and 4 sets
of 2 guiding rollers each. The arrangement of the 4 sets is
shown in the following figure.
Each roller is secured to the cabin supporting profiles and
the surface of the rollers is made of a material that ensures
smoothness though providing necessary endurance.

3.9 Cable management
3.9.1 Travelling cable
Travelling cable is connected from power supply socket
over mid tower´s height platform to service lift socket and it
features a cable stocking on each end. A travelling cable
pulley is suspended on the cable and is guided along the
traction and safety wire ropes.
3.10 Platform fences
The platform holes shall be protected with platform fences.
These platform fences consist of structures of different
geometries depending on the platforms where they are
installed.
The platform fences shall conform to EN 14122-3 and shall
be equipped with a door (sliding and/or swinging)
monitored with a trapped key system. Optionally, and apart
from the trapped key system, the platform fence doors
could feature guard locking switch system, or an electrical
switch monitoring system.
3.10.1 Fence door interlock system
3.10.1.1 Trapped-key system
The platform fence door is equipped with a trapped-key
lock that keeps the door locked while the service lift is not at
the platform. The door can be unlocked using the trapped
key in the cabin and opening the lock. The key will
remain trapped until the door is closed and locked again.

3.10.1.2 Guard locking system
The platform fence door could be equipped with an
interlock system that keeps the door locked while the
service lift is not at the platform. The door becomes
unlocked when the service lift is at the platform with the
lift detection switch activated. From the moment the fence
door is open, power is removed so the service lift cannot
move. When the door is closed, the ready light is on.
During emergency use, for example during a power
outage, where evacuation or rescue is necessary, the door
guard locking switch can be unlocked by acting the
mechanical Door Manual Release system from outside the
fence, or from inside the fence.
This system is installed in place of the Trapped-key
system.
NOTICE
Optional function.
NOTICE
A locking system is compulsory for CE versions if
the platform fences have doors.
3.10.1.3 Electrical switch monitoring system
An optional system is the electrical switch
monitoring system. This interlocking mechanism is
comprised of a mechanical locking unit and a switch
unit. When the switch is opened, the power is removed
so the service lift cannot move. This system allows users
to evacuate to the ladder more easily, without having to
jump over the fence. In this case, the fence doors must be
self-closing doors, to avoid any user could fall from a
platform if the fence door is left open.
3.11 Information signs and documents
The following documents, signs and stickers are supplied
with the service lift and must be always available.
Verify the integrity and legibility of all illustrations and
information signs. Replace any illustrations or signs that
are missing or an illegible.
