Abstract: A method and arrangement are disclosed for detecting a working condition of a mechanical brake of vertical transport equipment, the vertical transport equipment including a frequency converter, an electrical motor and a mechanical brake. Movement of the vertical transport equipment can be controlled using a frequency converter configured to feed electrical power to the motor, the mechanical brake being configured to mechanically hold a car or load of the vertical transport equipment. Data relating to deceleration of the car or load is used as reference data. The mechanical brake is controlled into a closed position for decelerating movement of the car or load. Test data, relating to deceleration of the car or load is measured from information or from a control system of the frequency converter, and compared with reference data.
