Abstract
A method for diagnosis and/or maintenance of a brake configured to apply braking force to a hoisting machine of a transportation system includes controlling the brake to start a brake control action, e.g. an opening and/or a closing action of the brake; monitoring the brake to detect a response of the brake to the brake control action, wherein in case of the response the response is detected in a predefined manner; measuring a brake operating time interval from a first point in time of starting of the brake control action until a second point in time of monitoring the brake to detect the response; and, if either the response has not been detected until the brake operating time interval reaches and/or exceeds a predetermined threshold or the response has been detected after the brake operating time interval reaches and/or exceeds the predetermined threshold, establishing an information indicating that an operation of the brake should be modified. A computer program realizing the method and a brake apparatus configured to execute the method are also disclosed.
