2.2 Platform lift operator
At least one responsible person must be appointed for each platform lift; this person must be easily
reachable during the operating time of the installation. The installation must be maintained in a safe
condition. If the system is found to be unsafe, it must be taken out of service immediately; danger
zones must be secured. Accidents must be reported immediately to the expert (lift inspector or
installation company) or the manufacturer.
The person in charge must make sure on a weekly basis that there are no obviously dangerous
operational defects and that the tasks listed in the chapter "Duties of the platform lift operator" are
being carried out carefully.
2.3 User group
The platform lift may only be used by competent, qualified and responsible persons who are familiar
with the system. The user must be able to assume responsibility for himself and for third parties.
Persons who do not meet these requirements, as well as children, may only be transported by
accompanying persons who also assume responsibility for the person being transported.
2.4 Range of application
The platform lift may only be used on stairs or accessible ramps. It is recommended to install the
system in predominantly dry rooms. The ambient temperature must not be below -15 °C or above
+ 40°C. This type is not suitable for use in unusual locations (e.g. explosive areas, areas with
aggressive media, etc.).
Outdoor use is possible in principle, however, in the case of outdoor installations that are exposed
to the weather, it may be necessary to clear parts of the installation of ice and snow in winter on a
case-by-case basis.
2.5 Qualified workers
Installation, maintenance, repairs and checks must be carried out by qualified persons, preferably by
companies authorised by Lehner Lifttechnik.
2.6 Decommissioning
When the unit is taken out of service for cleaning, maintenance or repair work, it must be protected
against unintentional movement. The key switches on the call stations must be switched off and the
keys removed.
