FIELD: machine building.
SUBSTANCE: invention relates to elevator (10) with sensor (8), through which can be detected vibrations generated during operation of elevator (10) and with signal processing circuit (9), which is connected to sensor (8) and through which vibrations detected by vibration sensor can be analysed. By means of signal processing circuit (9), detected vibrations can be compared with specified working value and with specified threshold value. Upon exceeding critical value of quality index, state change signal can be triggered. Invention also relates to a method of operating elevator (10).
EFFECT: designing more reliable control unit for controlling elevator components.
