6.1 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 travel 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. You can find the detailed instructions to perform the operational checks, inside the
maintenance schedules, in the following pages
Please, note that all checks are applicable only if the part is really installed.
