Maintenance and inspection
The WITTUR lift car frame requires little servicing.
Inspection checks must be carried out at regular
intervals (minimum twice a year with each service)
to guarantee safe operation. Alterations, damage
or other irregularities should be reported, and
repaired if possible. Frequent servicing and control
checks not only make operation of the installation
safer, but also ensure long and reliable lifetime.
It is recommended that control checks and servic-
ing be carried out before legally prescribed func-
tional tests (e.g. before TÜV tests).
The lift installation must be immediately
taken out of use should any damage or
irregularities to the lift car frame arise
which could possibly impair operational
safety.
Please contact us at WITTUR if you have
any problems or queries.
Maintenance work should be expertly car-
ried out with utmost care in order to guar-
antee safe installation operation.
