MAINTENANCE
4.1
PROGRAMMED MAINTENANCE
For a correct and safe lift use, it is necessary to make a preventive programmed maintenance, following a
fixed plan.
To define the periodical maintenance frequency, you should consider more events, particularly:
-
Number of travels per year
-
Travelling and stopping periods
-
Age and condition of the lift
-
Site and type of the building in which the lift travel
-
Passengers and goods demand
-
Inside and outside working condition (climate, vandalism, etc.)
In the next table, parts are shared in groups and for each group is shown the type of check and its longest
frequency recommended. Checks operative instructions are detailed in the maintenance schedules on
chapter.
Please, note that all checks are applicable only if the part is really installed.
