Electric Site Survey - on Quest of Elevator Parameters

摘要

In elevator modernization projects it is essential to know the system masses when engineering a new motor-drive system in the cases where existing hoist way mechanics is reused. Car acceleration together with the hoisting motor power will reveal the secrets of the elevator system parameters when state of the art sensor, measurement, modelling and optimization techniques are applied. The developed KONE ESiteSurvey method provides a comprehensive set of elevator system parameters readily after a round trip test run and out-of-service time less than 30 minutes. The parameters include e.g. masses, frictions, balancing, compensation, hoist motor and hoist way efficiencies. The method is now part of the KONE standard modernization process in the high-rise segment.
