Abstract: A method for monitoring an elevator system utilizes a mobile terminal device having at least one sensor to collect measurement values in an elevator car. The mobile terminal device is carried by a passenger of the elevator system. The collected measurement values are transmitted by the mobile terminal device to a central evaluation unit where they are evaluated. The mobile terminal device activates a measurement mode when it detects that it is located in a region of a shaft door of the elevator system.

Abstract: An elevator safety supervising entity (SSE) includes a car safety supervising unit (SSU) controlling functions of car safety components and having at least one car sensor sensing car-related parameters, a head SSU controlling functions of shaft safety components and having at least one shaft sensor sensing shaft-related parameters, and a data linkage transmitting signal data between the SSUs. Both SSUs detect a failure in the other one of the SSUs and in the data linkage signal data transmission and in response switch from a normal operation mode to a failure operation mode. In the failure operation mode, the SSUs operate autonomously to keep the elevator operative at least temporarily with a sufficiently high safety even when functions of the elevator SSE are disturbed due to failures and e.g. passengers may be evacuated from the elevator car before completely stopping elevator operation.

Abstract: A method determines information relating to elevator components received in an elevator shaft, the elevator components each being provided with a machine-readable marker on which component-specific information is stored, which information is read out by a marker reading device. In the method, a movable elevator element on which the marker reading device is arranged is moved through the elevator shaft and the component-specific information is read out from the markers. The markers can be, for example, markers that can be read out electromagnetically and in a contactless manner, such as RFID tags. The method also includes a comparison of the read-out component-specific information with nominal specifications, and the compiling of a report indicating instances of conformity and/or differences between the read-out component-specific information and the nominal specifications.

Abstract: An aligning device is used for aligning a guide rail of an elevator system. The guide rail is held on a shaft wall of an elevator shaft and is displaceable in at least two horizontal directions, oriented crosswise with respect to each other, before a final fixation. The aligning device has a detection device that is configured to detect, in an automated manner, a position deviation of the guide rail from a nominal position, and has a hammer mill that is configured to hammer the guide rail in an automated manner depending on the detected position deviation by exerting pulse-like strikes in one of the horizontal directions toward the nominal position.

Abstract: In an elevator system, a measurement system is provided in addition to an elevator car, an elevator controller and a transferring device configured to transfer electrical energy and/or information between the elevator car and the elevator controller. The measurement system has a transmitting device and a detection device which can be positioned separate and remote from the transmitting device by an air path. The detection device receives a measurement signal emitted from the transmitting device as electromagnetic radiation via the air path and converts it into an electrical signal. The transmitting device receives the electrical signal via the transferring device, determines a propagation time of the measurement signal over the air path by means of the electrical signal, and determines a distance (d) between the transmitting device and the elevator car by means of the propagation time.
