4SAFETY DEVICES
The Liftboy platform lift is equipped with the following safety device:
4.1 Access ramp
The ramp, which has to be folded up during the ride, prevents a fall in longitudinal direction. This
always opens automatically in the lower stop as long as the travel command is held down.
4.2 Safety curtain
The safety curtain is fitted around the platform mechanics and serves as an intervention protection.
4.3 Safety bar (optional)
The safety bar serves as a visual fall protection at the upper landing when the platform is at the
bottom.
4.4 Circumferential contact bars (optional)
Contact bars can be fitted to the sides of the platform floor which prevent jamming in the
downward direction of travel when the unit is mounted in a pit. The travel command in the
opposite direction remains active.
4.5 Overload device
The platform is equipped with an overload device in upward travel. If the load capacity specified on
the type plate is exceeded, an overcurrent potentiometer switches off the system. In this state, it is
not possible to drive up.
The platform must never be overloaded. In case of overload, reduce the excess load
immediately.
4.6 Emergency stop
The Liftboy platform lift is equipped with an emergency stop button. If you need to stop the platform
in an emergency, press the red button and the lift stops. Unlocking is done by pressing it again or
turning it clockwise.

Liftboy 1-3 | User and Installation Manual Version 07/2023 Page 10
5INSTALLATION AND COMMISSIONING
The system may only be set up and commissioned by a competent
partner company of Lehner Lifttechnik GmbH. When setting up the lift,
it must be ensured that no impacts or vibrations from neighbouring
machines have an effect on the system. This could affect the electronics
or the precision mechanics of the lift. The load-bearing capacity must
be checked on the basis of the support load per unit area.
5.1 Installation site
The detailed installation drawing for your system is in the box we supply. This box also contains the
charger and the corresponding control unit (radio remote control (optional), hand cassette and
transformer).
It is important that the floor at the installation site is level and horizontal. The platform
mechanism and the underlying frame of the platform must be in full contact with the
floor. If this is not the case, the platform mechanism will be deformed and damaged
which can result in an accident!
If the ground is not horizontal, the platform must NOT be brought into a horizontal position by
using shims or wedges. In this case, the floor or the foundation must be adjusted! The installation
surface must be level and horizontal!
Take a look at
the installation
video of the
Liftboy 1/2/3
Shims or wedges are not allowed!

Liftboy 1-3 | User and Installation Manual Version 07/2023 Page 11
5.2 Transport of the site
Take the pallet to the installation site and unpack the cardboard box.
Now lift the platform down from the pallet.
You must grasp the platform underside to be able to lift the platform - see picture below
right. Never lift the platform by the top. This could damage the platform mechanism!
5.3 Assembly of the plant
Now mount the ramp and attach the ramp motor to the ramp.
Reach around the bottom!

Liftboy 1-3 | User and Installation Manual Version 07/2023 Page 12
Mount the side barriers. Pay attention to the wiring of the emergency stop button as well as the plug
connection for the hand cassette.
Attach the cover flaps to the side barriers and the rubber strip to the underside of the ramp.
Connect the hand cassette and the transformer to the platform lift.

Liftboy 1-3 | User and Installation Manual Version 07/2023 Page 13
To adjust/change the lifting height, the upper limit switch must be moved to the correct position.
Move to the desired upper position and open the safety curtain.
Now the limit switch can be loosened and moved to the correct position. The correct position is
found when the limit switch is actuated by the mechanical stop. A soft click should be audible in the
switch here.
Check several times the ascent and descent of the installation (with and without load) as well as the
correct stopping at the upper stop and the function of the drive-up ramp in the lower stop. Now
the Liftboy is completely assembled.
If you have any problems or questions, contact your Lehner Lifttechnik partner or customer service
immediately. Installation work on the entire system may only be carried out by the manufacturer or
its authorised partner companies. Failure to do so will invalidate the operating and warranty permit
and result in the exclusion of liability for consequential damage of any kind.
5.4 Dismantling and disposal
Dismantling work on the entire system may only be carried out by the manufacturer or its authorised
partner companies. According to the European Directive 2002/96/EC on waste electrical and
electronic equipment and its implementation in national law, used electrical equipment must be
collected separately and recycled in an environmentally sound manner.

6OPERATING ELEMENTS
6.1 The Transformer
The transformer connects the system to the power grid.
The connecting cable with the plug is located on the side of the platform
base.
The transformer must be connected so that the system is ready for
operation. By disconnecting it, the power can be switched off on the
entire system and the control unit.
6.2 Controls on the platform
The platform is equipped with a hand cassette on the spiral cable as standard. This allows an
ergonomic sitting position while operating the platform.
The travel buttons are located on the hand cassette. An emergency stop button and optionally a
key switch are mounted on the platform. The hand cassette is only used to drive the platform and
to open and close the access ramp.
Alternatively, or additionally, the operating elements can also be attached to a control pillar.

Liftboy 1-3 | User and Installation Manual Version 07/2023 Page 15
6.3 Call stations at the stops (optional)
Landing control stations can be located at each stop. The control station must be activated with the
key switch before operation. The control stations are used for calling and sending, as well as for
opening and closing the access ramp. The landing control can be hard wired or with radio signal.
The radio control stations flashes a green light when the radio signal is working. The radio control
stations are powered by 2 x AAA / 1.5V batteries as standard. The battery life is approx. 1 year.
The status of the radio cassette can be read from the LED:

7OPERATING THE PLATFORM
The platform lift is safe and easy to use. The operation is optimally adapted to the user with walking
difficulties.
Before moving the platform, make sure that nobody is endangered by the movement of
the platform and the optional revolving doors. If a dangerous situation arises while the
platform is moving, stop the platform immediately by releasing the command button!
7.1 Call the platform
If the platform is not at the desired stop, it can be summoned with the call station. The platform can
only be controlled from the stops when the optional revolving doors are closed.
▪Switch on the call station by inserting the key and turning it. The green lamp now lights up.
▪Press the move command button "Up" or "Down". The platform moves in the corresponding
direction as long as the button remains pressed. If you release the button while the platform
is moving, the platform stops immediately.
▪The platform stops independently when reaching the stops.
▪In the lower stop, the access ramp opens automatically as long as the drive-down command
remains pressed.
▪Switch the optional call station off again when the platform has stopped in the stop by
turning and removing the key.
The lift can only be controlled from the stops when the revolving doors are closed.
7.2 Opening the ramps / revolving door and driving on the platform
At the lower stop, the access ramp opens automatically as long as the drive-down command remains
pressed.
A revolving door is optionally possible at the upper stop.
Manual revolving door (optional)
When the platform has reached the upper landing, the revolving door can be opened manually.
When the door is opened, the control commands of the call stations are automatically cancelled so
that the platform cannot be operated by another person at the same time and safe travel on the
platform is ensured.
You can now drive on the platform.
Close the revolving door manually again; this enables steering from the platform.
Automatic revolving door (optional with Liftboy 3)
When the platform has entered the landing, the revolving door opens automatically. Please note
that you are not in the door's turning range while it is opening.
