Abstract

The present invention relates to an elevator system for which maintenance is tailored for each of the individual hardware components of the elevator. A maintenance system groups together hardware components having approximately identical maintenance needs, and stores these groups along with the appropriate maintenance data for these groups in a storage area. The maintenance data stored in connection with each group includes maintenance time-points that indicate the times when the group of components should be maintained. The storage area of the maintenance system can be accessed and changed by remote devices. Components needing more maintenance are store in different groups from components needing less maintenance, thereby reducing unnecessary maintenance of elevator components.
