| titleOfInvention | Method and test system for testing failure of a machinery brake of an elevator |
| abstract | The purpose of the invention is to detect a failure situation wherein the machinery brake of an elevator does not open sufficiently. In the method for testing failure of a machinery brake of an elevator: the machinery brake is set to open; after this, a test torque pulse is generated at the traction sheave; movement of the elevator machine is measured in connection with the torque pulse; if the torque pulse does not move the machine, it is deduced that the machinery brake has not opened and has therefore failed. Most preferably a shorter time is selected for the duration of the torque pulse than the time according to the transfer function of the elevator mechanics for transmitting movement of the traction sheave into movement of the elevator car, in which case the torque pulse is not noticed in the elevator car. This enables testing of a machinery brake when the elevator car is manned. |
