Abstract

According to an aspect, there is provided a method for condition monitoring of inductive braking device of an elevator car in an elevator shaft, the method including determining that the elevator car is empty; determining that doors of the elevator car are closed; causing electromechanical brakes to hold the elevator car stationary in the elevator shaft; causing actuation of a braking condition for the elevator car with the inductive braking device; causing the electromechanical brakes to lift while the inductive braking device is in the braking condition; determining a value associated with the inductive braking device in response to causing the electromechanical brakes to lift while the inductive braking device is actuated; and determining an operating condition of the inductive braking device based on the value.
