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.

Abstract: A brake assembly for an elevator includes a brake, a brake operating device and a first brake wire connected to the brake operating device and to the brake, the brake operating device being configured to release the brake by moving the brake operating device and the first brake wire to a first direction. A second brake wire is connected to the brake operating device and to the brake, and the brake operating device is configured to engage the brake by moving the brake operating device and the second brake wire to a second direction.

Abstract: An elevator drive apparatus is described which includes a drive unit for driving an elevator car, a brake device for braking a motion of the elevator car, a detector for detecting an electrical operation amount of the drive unit, and a controller. The controller is configured to release the brake device, to compare the detected electrical operation amount with a threshold, and to apply the brake device when the detected electrical operation amount exceeds the threshold. In this way, it is ensured that a speed of the elevator car in case of a rescue situation is within a safety limit.

Abstract: A backup circuit for supplying electricity to an electronic overspeed governor in connection with a malfunction of a main electricity supply is disclosed. The backup circuit includes an energy storage. The backup circuit is configured to disconnect the supply of electricity from the energy storage to the electronic overspeed governor with a delay when the malfunction of the main electricity supply is detected, and when the malfunction of the main electricity supply continues for a predetermined amount of time, restarting the supply of electricity from the energy storage to the electronic overspeed governor.
