Timely maintenance of an elevator drive is very important for ensuring its safe operation.
A stationary vibration monitoring and diagnostics system for a 'motor/gear' assembly together with monitoring of rope on the pulley ensures predictable destruction monitoring and also provides indication/warning for a dispatcher and maintenance service about required interference on the basis of warning level values and emergency condition values.
Also, this 'traffic-light' indication of the elevator drive's equipment state is indicated for the passengers when they call the elevator to avoid accidents.
