Abstract: A temporary platform for assembling elevator equipment in an elevator shaft is arranged substantially in the region of a shaft opening, such that the platform partially sits on a floor surface of the building and partially protrudes into the elevator shaft. The platform includes a bottom frame and bottom plates that lie on or are inserted into the bottom frame. The bottom frame also includes two lateral bottom bars, at least one front and one rear transverse bar that interconnect the two lateral bottom bars, and at least two intermediate bars that are arranged parallel to the two lateral bottom bars. The two intermediate bars are supported substantially by the front and the rear transverse bars.

Abstract: The application relates to a method for the digital documentation and simulation of a passenger transport installation using a detection apparatus. Connection components are installed using a tool of the detection apparatus, the detection apparatus measuring the position and installation parameters of said components during installation, and these data being entered as installation data records in a position-defined manner into a digital twin data record mapping the physical passenger transport installation.

Abstract: A working device for carrying out fitting or maintenance work in an elevator shaft includes at least one working platform having a standing surface and a railing. The standing surface affords space for at least one person and the railing at least partially encloses the standing surface. The working device also includes at least one additional platform that is attachable to the railing of the working platform, and wherein the additional platform affords an additional standing surface for at least one person. The additional standing surface is arranged above the railing of the working platform.

Abstract: A control system of an elevator can be communicated with by a mobile control device to execute a maintenance and/or installation for the elevator. The control system includes a receiving element for receiving a request to establish a communication connection from the mobile control device, at least one processor to perform a first identification whether the mobile control device is authorized to communicate with the elevator, the at least one processor to perform a second identification whether a user of the mobile control device is authorized for using this mobile control device and/or for servicing this elevator, the at least one processor for matching a right of access of the mobile control device to the elevator depending on results of the first and the second identification, and a communication element to establish the requested communication connection according the matched right of access of the mobile control device.

Abstract: A method for operating an elevator installation uses an elevator control device, wherein, by at least one sensor allocated to the elevator installation and by a sensor signal obtainable therefrom, a state of the elevator installation is automatically detected by the elevator control device. In dependence on the detected state, the elevator control device automatically generates an activation signal to automatically activate a remote signaling element.

Abstract: An elevator system includes an elevator car carrier moveable in a travel space to a plurality of floors. The elevator car carrier has a first elevator car and a second elevator car adjustably arranged thereon, as well as a drive unit. An adjustment device includes a first traction device and a second traction device, which traction devices are wound in the opposite sense onto drums of the drive unit. The distance between the first elevator car and the second elevator car can be adjusted by a rotation of the drums to adapt to varying floor distances.

Abstract: An elevator has an elevator car supporting frame that can travel in a travel space provided for a journey of the elevator car supporting frame. The elevator installation is also provided with a first elevator car and a second elevator car arranged on the elevator car supporting frame. Furthermore, a hydraulic moving element is arranged in a lower end region of the travel space. In this way, the first elevator car can be moved in relation to the second elevator car, by the moving device, in the lower end region of the travel space.

Abstract: An elevator installation includes an elevator cage carrier movable in a travel space provided for travel of the elevator cage carrier. Moreover, a first elevator cage and a second elevator cage are adjustably arranged at the elevator cage carrier and a drive unit arranged at the elevator cage carrier. In addition, an adjusting device with a first traction means and a second traction means guided in opposite directions around a drive roller, drivable by the drive unit, is provided. In that case the spacing between the first elevator cage and the second elevator cage is adjustable by movement of the elevator cages in opposite directions. An adaptation to different story spacings is thereby possible.
