Abstract: In order to improve safety, an escalator system is configured to drive an escalator in response to a signal received from a user interface located in a first end of the escalator, and to stop movement of the escalator in response to detection of opening of an access cover plate in a second end of the escalator.

Abstract: This invention relates to a method for defining absolute position information of an elevator car. The method comprises: obtaining continuously a pulse position information of the elevator car; and defining an absolute position information of the elevator car by adding a predefined correction value to the obtained pulse position information of the elevator car. The predefined correction value indicates a drift between the obtained pulse position information of the elevator car and the actual pulse position of the elevator car. The invention also relates to a safety control unit and an elevator system performing at least partly the method.

Abstract: An escalator system includes a pit having an access cover plate, a detector indicating when the access cover plate is open and when it is closed, and a user interface which is located in said pit and which in an active state provides the escalator system with control signals controlling the operation of the escalator and which in a passive state does not affect the operation of the escalator. In order to improve the safety of the escalator system the escalator system is configured to stop movement of the escalator if the detector indicates that the access cover plate is closed while the user interface is in the active state.

Abstract: A method for dynamically adjusting a levelling speed limit of an elevator car during a levelling operation includes obtaining an indication that the elevator car is detected to arrive to a zone; obtaining at least one value indicating the speed of the elevator car, in response to detecting that the elevator car arrives to the zone; and dynamically adjusting the levelling speed limit of the elevator car based on the speed of the elevator car. An elevator control unit and a system are provided to perform at least partly the method.
