Foreword
Dear Reader,
these Operating Instructions serve to provide all information required
for the safe use of the linear lift.
The linear lift is designed and constructed in accordance with state
of the art technology and recognised safety standards. Persons and
materials can however be endangered, as not all danger areas can
be eliminated if the functional capability is to be maintained. Ac-
cidents caused by these dangers can however be prevented by
strictly observing these Operating Instructions. Over and above this,
the operational efficiency of your linear lift can be used to the full and
unnecessary faults can be prevented.
After reading these Operating Instructions for the first time, keep
them in a safe place for future reference over the entire lifetime of
the linear lift. Chapter 12 of these Operating Instructions contains an
Inspection Log that is required by the technical expert for his / her
annual inspection of the linear lift.
If you sell the linear lift, hand these Operating Instructions over to the
new owner.
All details, figures and dimensions contained in these Operating In-
structions are non-binding. No claims in any form can be derived
from these.
This document must not be reproduced or duplicated, in full or in
part, without the prior, written permission of the manufacturer.
The linear lift must never be converted or modified in any way, wit-
hout seeking the prior, written permission of the manufacturer. The
manufacturer will not be held responsible in any way whatsoever if
conversions or modifications are carried out without authorisation.
Use only original spare parts or spare parts which have been appro-
ved of by the manufacturer. If spare parts other than these are
used, this can have a negative effect on the specified characteris-
tics, the functionality and safety of the linear lift. Using non-original or
unauthorised spare parts will render the guarantee null and void.
Contact our customer service department to order spare parts or
accessories. The spare parts catalogue can be found in the service
section of our Internet site (see Chapter 15, page 70).

1.6 Safety Devices
1.6.1 Guardrails
The guardrails fold down to the horizontal position, together with the
platform, when the linear lift’s platform is lowered from the stowed
position to the deployed position. They provide support for the
passenger and increase the sense of security when the platform is
being raised or lowered.
1.6.2 Roll-off guard
A roll-off guard is fitted to the side of the platform furthest from the
vehicle. When the platform is raised, the roll-off guard rises automa-
tically and latches in position. This prevents the passenger in their
wheelchair from rolling off the platform.
1.7 Safety and Accident Prevention
Regulations
Adhere to the following notes in order to prevent personal injuries
and material damage. Also adhere also to the relevant safety and
accident prevention regulations laid down by the trade associations.
y The linear lift must only be operated if all safety and protective
devices are correctly fitted (see Section 1.6, page 11). Such de-
vices must only be removed in order to enable maintenance and
repair work to be carried out. All safety and protective devices
must be replaced immediately after such work has been comple-
ted. If they are not replaced correctly, there is a high risk of injury.
y The linear lift must only be used for the purpose for which it is in-
tended, otherwise dangerous situations, with resultant injuries,
may occur (Proper use: see Section 1.1, page 8).
y The owner is responsible for ensuring that proper use is adhered
to, in particular that the linear lift is only operated by authorised
persons.
y If the linear lift is used commercially or as a public utility, the ow-
ner must ensure that operating personnel are familiar with the
operation of the linear lift under all operating conditions by giving
training and familiarisation courses.
y In order to be able to transport wheelchair-bound persons, the
vehicle must be fitted with the necessary special equipment in
accordance with DIN EN 75078. To prevent dangers in road traf-
fic, the linear lift must be equipped with warning lights or warning
markings.

Safety
Page 12 of 72 Linear Lift AL1
y A number of dangers may arise during operation due to adverse
lighting conditions. The owner is obliges to equip the vehicle or
the linear lift with the corresponding lighting fixtures.
y It is forbidden for persons to ride on the platform id they are not
in a wheelchair.
y Proper use of the linear lift also includes adherence to the spe-
cified maintenance and repair work, in particular strict adherence
to the maintenance intervals. If such work is not carried out,
trouble-free operation can not be guaranteed. Risks of personal
injury and material damage can occur. We recommend that
maintenance records be kept.
y If the linear lift is used commercially or as a public utility, it must
be inspected by a technical expert at intervals of not more than 1
year after commissioning. During inspection, faults affecting the
safety should be systematically identified and remedial action ta-
ken (see "Inspection Log", page 56).
y Do not deposit any items on the linear lift. Persons can suffer inju-
ries if such items fall off the platform.
y The linear lift must not be operated in a faulty condition, as seri-
ous injuries may be caused by this. If faults occur, do not use the
linear lift until repairs have been effected.
y Switch the linear lift OFF before carrying out maintenance or re-
pair work, this includes cleaning work. Make certain that no other
person can switch the linear lift ON (e.g. by disconnecting the
starter battery). If this is not done, there is a risk of injury.
y Use only original spare parts or spare parts which have been ap-
proved of by the manufacturer. If non-original or unauthorised re-
placement parts are used, this will render the guarantee null and
void.

2 Description
Persons who are wheelchair-bound can be embarked into or
disembarked from a vehicle using the linear lift.
The main components of the linear lift are:
y the platform,
y the lifting unit with carrier arms, guardrails and floor anchorages,
y the hydraulic system and
y the operating controls.
The aim of this chapter is to illustrate the construction and function
of the linear lift. To this end, the individual assemblies and compo-
nents are described in the following sections.

2.1.1 Platform
The platform has an anti-slip grating surface and is equipped with
side roll-off guards. These prevent the passenger’s wheelchair from
rolling off the side of the platform.
A roll-off guard is fitted to the side of the platform furthest from the
vehicle (see Figure 1, page 13). When the platform is lowered fully to
the ground, the roll-off guard folds down. This provides the passen-
ger in the wheelchair with easy access the platform. As soon as the
platform is raised from the ground, the roll-off guard rises and lat-
ches in position. This prevents the passenger’s wheelchair from rol-
ling backwards off the platform.
Figure 2: linear lift AL1 Solid, Embarkation and Disembarkation Level
The linear lift AL1 Solid has a one-piece platform. The platform of the
linear lift AL1 Panorama is made up of two sections such that it is
shortened when folded up to the stowed position.

This enables a linear lift with a long platform to be installed in vehic-
les with restricted interior height. In addition to this, the driver has a
clear view through the rear window when driving. Over and above
this, the fact that a linear lift is installed in the vehicle can not be
seen from the outside (see Figure 3 and Figure 4).

The platform of the linear lift AL1 Split is split lengthwise. When it is
stowed in the driving position, the two halves of the platform separa-
te (see Figure 5). Because of this, it is possible to enter and leave
the vehicle by way of the door in which the linear lift is installed, even
though the linear lift is in the vertical, stowed position.
Figure 5: linear lift AL1 Split, Stowed Position
2.1.2 Transfer plate
A transfer plate is fitted to the linear lift. When the platform reaches
the same level as the vehicle’s floor when being raised (embark /
disembark level), the transfer plate closes the gap between platform
and vehicle. This ensures convenient, safe embarkation / disembar-
kation (see Figure 1, page 13 and Figure 2, page 14).
2.1.3 Lifting unit
The lifting unit represents the connection between platform and ve-
hicle. The lifting and lowering movements are carried out by four
carrier arms that are powered by hydraulic cylinders (see Figure 1,
page 13). The carrier arms act on carrier struts, to which the plat-
form and guardrails are attached. The platform and guardrails auto-
matically fold down on elbow joints actuated by the carrier arms
when the linear lift is lowered from its vertical position.
When the linear lift is raised to a level above the floor of the vehicle,
to the stowed position, the guardrails and platform are folded up to
Platform

Description
Linear Lift AL1 Page 17 of 72
the vertical, stowed position. Because of this, the linear lift takes up
a minimum of space in the vehicle (see Figure 5, page 16).
The carrier arms are connected to the vehicle by the floor anchora-
ges (see Figure 2, page 14).
2.1.4 Hydraulic system
The hydraulic system’s motor, pump and oil reservoir are located in
the switch box on the side of the linear lift (see Figure 1, page 13).
The operating voltage for the motor is supplied by the starter bat-
tery. The hydraulic cylinders that are powered by the pump are lo-
cated between the carrier arms.
The hydraulic system can be manually operated in an emergency.
2.2 Rating Plate
A rating plate, which contains the fundamental data, is attached to
the linear lift (see Figure 6). The rating plate is located on the floor
anchorage.
