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.

A method and a device for monitoring an elevator car door acquire one or more distances based on light emitted toward the car door by a distance measuring device and reflected at the car door as a function of a current closed state of the car door. Information about the current closed state of the car door is derived solely by comparing the acquired distance with a previously acquired reference distance, and a signal which represents the information can be fed to a remotely arranged control center. The monitoring device can be installed as a retrofit component that is capable of working autonomously in existing elevator systems, does not need to receive any data from a controller of the car door or the elevator system and only requires a relatively simple data processing device that only needs to carry out a comparison of detected distance values with reference values.

An elevator renewal construction method includes steps of: replacing an old control panel of an existing elevator with a new control panel; installing an auxiliary panel, which includes a communication converter to be connected to the new control panel, and which is formed separately from the new control panel; and connecting an old device including at least any one of an old hall device and an old car device, which has been placed in a communicable state with the old control panel of the existing elevator, into a communicable state with the new control panel via the communication converter, wherein the new control panel is configured to be communicable with the old device through an old communication system converted via the communication converter included in the auxiliary panel, the communication converter being configured to mutually convert a communication system between a new communication system and the old communication system.

Floor content information of an elevator is described. According to an embodiment, a device is disclosed, comprising: a processor; a storage comprising a set of instructions; wherein the set of instructions cause the processor to: Receive a destination floor of the elevator; Receive information describing content of the destination floor, wherein the content identifies the content located within the destination floor; Based on the destination floor and the information describing the content of the destination floor, display a data notification to at least one user using the elevator travelling to the destination floor. According to other embodiments, an elevator, a method and a computer program product is described along with the features of the device.

To provide a 3D data acquisition device, a 3D data acquisition system, and a 3D data acquisition method for an elevator which are capable of improving measurement accuracy of 3D point group data on an inside of a shaft. The 3D data acquisition device for the elevator includes: a housing that constitutes an outer shell; and a plurality of 3D distance imaging sensors which are provided in the housing so as to directly face each of a plurality of side walls of a shaft of the elevator on a horizontal projection plane and which acquire 3D point group data. According to the configuration, measurement accuracy of 3D point group data on the inside of the shaft can be improved.

An elevator door subsystem including a hanger mount, a leveling cam, an engaging member, and a roller assembly, configured such that when the roller assembly is positioned on one side of the elevator door hanger, the hanger mount is positioned within an opening of the elevator door hanger, and the leveling cam is positioned on another side of the elevator door hanger, the engaging member is receivable by the roller assembly after the engaging member is passed through an opening in the leveling cam, an opening in the hanger mount, and the opening in the door hanger.

An escalator or a moving walkway has two access regions, each with a comb plate, and a conveying region arranged between the access regions. The conveying region extends between the two comb plates of the access regions. At least one projection projects into the conveying region at at least one stationary part of the escalator or moving walkway. At least one monitoring sensor is arranged at least partly in the at least one projection.

An elevator system is provided that includes an elevator car, a counterweight, a load bearing flexible member, a motor having a drive, and an elevator control system. The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit and a power storage device. The power storage device includes a supercapacitor unit and a battery unit. The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device.

The present invention provides an elevator system which prevents interruption of communication with a wireless communication device installed in a car, while suppressing the cost. The elevator system includes the car ascending/descending in a hoistway, multiple hoistway wireless communication devices installed in the hoistway, and a car wireless communication device installed in the car. The elevator system is configured to allow communication between the hoistway wireless communication device and the car wireless communication device. A spacing between the hoistway wireless communication devices which are installed at positions near a vertical center of the hoistway is smaller than a spacing between the hoistway wireless communication devices which are installed at positions farther from the vertical center.

A device for synchronously actuating and locking elevator doors, which are situated essentially one behind the other in the passage direction—such as a car door and a shaft door; the device includes entraining skids that are fastened to a first door by means of an entraining skid support and whose spacing relative to one another can be changed in order to be able to couple the first door to the second door and move the two doors together and the device is coupled to a linear drive unit that moves the doors in the opening and closing directions, characterized in that the entraining skid support has a plurality of first openings that make it possible to mount at least one, preferably both, of the entraining skids on the entraining skid support in different functional positions.
