Abstract: A method for constructing at least two elevators in a building under construction adapts the usable lifting heights of the elevators to an increasing height of the building, wherein each of the elevators is arranged in an elevator shaft of the building associated with the elevator and includes a drive platform having an elevator drive machine that supports and drives an elevator car and a counterweight by a traction sheave and at least one flexible suspension device. In order to adapt the usable lifting heights, lifting operations are performed in which in alternation one of the drive platforms is raised to a higher level in the associated elevator shaft and is locked there. A single lifting platform is temporarily fastened above the particular drive platform to be lifted to apply a lifting force required to raise the drive platform, which force is transferred to supporting elements of the elevator shaft.

Abstract: A passenger transport system sensor network has a master unit, a signal-transferring apparatus, and a plurality of sensor nodes each having at least one sensor sensing a physical measurement variable and transferring the sensed variable to the master unit via the signal-transferring apparatus. A sensor-identifying module in the master unit determines the identity of the sensors from information, stored in a database, of: a first information type about reference measurement results to be typically provided by a particular sensor under already known conditions; a second information type about the identity of a sensor node containing the particular sensor, the sensor node having a plurality of different sensors or a plurality of identical sensors in different configurations; and/or a third information type about a configuration of a sensor node holding the particular sensor, which configuration was defined in advance. Sensor identities and installation locations can be determined in an automated manner.

Abstract: An elevator operation panel has a plurality of buttons for selecting target floors and a plurality of touch-sensitive areas, each area being associated with one of the buttons. The panel includes an output device, such as a display or a loudspeaker, for outputting information, a control unit connected to the buttons, to the areas and to the output device, and a data storage device storing at least one data folder for each target floor.

Upon triggering one of the touch-sensitive areas, the control unit reads the information in one of the folders relating to the target floor selectable by the button to which the area is associated and outputs the information at the output device. Subsequent triggering of the same area causes the control unit to read another folder related to the target floor and output the information therein.

To secure the erected position, the balustrade has a locking mechanism by which the balustrade can be locked via a latching connection during a pivoting movement to produce the erected position. The balustrade includes a two-part post with a lower post part and an upper post part, the upper post part being pivotably fastened to the lower post part and on which the locking mechanism is arranged. A latching element of the locking mechanism is mounted vertically on the lower post part so as to be displaceable to a limited degree.

Abstract: A pulley for an elevator includes a base body made e.g. from steel and having a rotation-symmetrical circumferential surface. Additionally, a friction reducing coating is applied to the circumferential surface of the base body. Due to the friction reducing coating and, optionally, due to additionally smoothing the base body's circumferential surface before depositing the coating, a very low friction between an outside surface of the pulley and a contacting surface of a suspension traction member may be obtained. Thereby, guiding characteristics of the pulley may be improved and/or alignment requirements upon installation of the pulley may be relaxed. Preferably, the coating may comprise diamond-like carbon (DLC) or chromium nitride (CrN) such that the coating provides for superior wear resistance, slickness, corrosion protection and electrical characteristics.

Abstract: A method for fastening a rail of an elevator system to a bearing element fixed in an elevator shaft utilizes a clamp set having a clamp and a spacer. The clamp is arranged on a side part of a rail foot arranged on the bearing element whereby the clamp connects to the bearing element in a fastening zone of the clamp and a contact zone of the clamp is situated on a bearing side on an upper face of the side part. The spacer defines a mounting distance between the contact zone and the bearing side such that the clamp is partly elastically and plastically deformed in the fastening zone when connected. The spacer is then at least partially removed so that a distance between the contact zone and the bearing side is reduced.

Abstract: An elevator installation wherein damage to a support for an elevator car and a counterweight, in particular damage to a sheath of the support, advantageously can be detected. At the elevator installation, a housing at least partially extending around the support, for example at a deflecting roller arrangement. A surface of the housing facing the support is electrically conductive and is electrically grounded. If the support or a wire coming out of the damaged support comes in contact with the housing, an electrical ground fault results. The ground fault can be detected by a security monitoring unit by monitoring a current flowing through the wires of the support, and the damage to the support can thus be inferred.

Abstract: A system and a method determine the position of an elevator car of an elevator installation, which elevator car is arranged movably in an elevator shaft. The system has a computing unit and an image-capturing unit that are arranged on the elevator car. The image-capturing unit records images of shaft components or shaft equipment used for other functions and transmits the images to the computing unit. The computing unit compares a currently recorded image with at least one stored comparison image of the shaft components or shaft equipment in the direction of travel of the elevator car so as to determine the current position of the elevator car in the direction of travel. The computing unit compares the currently recorded image with the stored comparison image also transversely to the direction of travel so as to determine the current position of the elevator car in the direction of travel.

Abstract: A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

The relative position of the first reference element is determined with respect to at least two different sensor positions and thus positions of the installation component.
