Abstract

A method and arrangement for detecting a working condition of a mechanical brake of vertical transport equipment, the vertical transport equipment comprising a frequency converter, an electrical motor and a mechanical brake. In the method, movement of the vertical transport equipment being controlled using the frequency converter that is adapted to feed electrical power to a motor and the mechanical brake is adapted to mechanically hold a car or load of the vertical transport equipment when said car or load is stationary. The method comprises storing data relating to deceleration of the car or load for use as reference data, controlling the mechanical brake into a closed position for decelerating movement of the car or load, determining test data relating to the deceleration of the car or load from measured information or from a control system of the frequency converter, comparing the reference data with the test data, and producing an alarm signal on the basis of the comparison between the reference data and the test data.
