Value is placed on long lifetimes and safety in the
development and production of Nussbaum prod-
ucts. To guarantee the safety of the operator, prod-
uct reliability, low running costs, keep the warranty
and also the long-lifetime of the product, proper
set up and operation is just as important as regular
maintenance and sufficient care.
Our platforms fulfil or exceed all safety standards of
the countries we supply to. For example, Europe-
an regulations require a service by qualified experts
every 12 months of work of the platform. To guar-
antee the largest possible availability and function-
al capacity of the lift system, ensure the list of any
cleaning, care and maintenance work is done.
After first commissioning the lift is to be serviced at
regular intervals of a maximum of one year by an
authorized person according to the following plan.
For intensive operation and higher degree of con-
tamination shorten the service interval.
The complete function of the lift is to be observed
during daily use. Customer service must be in-
formed of any malfunctions.
