ABSTRACT:
Methods and apparatus for improving the servicing of an elevator system based upon the actual usage of its many functions. The usage of predetermined elevator system functions is monitored and data is collected relative thereto. Threshold and limit parameters are provided for the monitored functions, which parameters are periodically compared with the usage data. The reaching of a usage threshold parameter by a monitored function results in predetermined associated maintenance services being added to a maintenance due list. When a monitored function reaches its associated limit parameter, a need for scheduled elevator preventive maintenance is indicated for all of the maintenance services on the maintenance due list.
