The elevator that vertically conveys persons has an elevator car which is movable in the shaft and at least two counterweights which are movable together with the car in the shaft in a direction of movement opposite to the direction of movement of the elevator car. The elevator car and the counterweights are driven by drive engines with traction sheaves. The lift that vertically conveys objects may be a self-propelled lift. A lift platform of the lift overlaps at least partly a vertical projection of the elevator car, whereby preferably the vertical projection of the lift platform is smaller than the vertical projection of the elevator car.

Abstract: A transportation system for a building with multiple floors includes a shaft in the building, a traction sheave drive type elevator and a lift. The elevator vertically conveys persons using an elevator car that is movable in the shaft together with at least two counterweights, the elevator car and the counterweights moving in opposite directions. The elevator car and the counterweights are driven by drive engines with traction sheaves. The lift vertically conveys objects and is designed as a self-propelled lift. The lift has a lift platform designed as a vehicle for supplying goods, which vehicle can be brought in and out the shaft and which lies, when located in the shaft, within a vertical projection of the elevator car.

Abstract: An elevator system includes an elevator car that is movable in an elevator shaft in the vertical direction, a closed support belt guided about a lower deflection roller and an upper deflection roller and a drive machine driving the support belt. A drive connection is made between the support belt and the elevator car with a coupling device arranged on the elevator car that is coupled to a coupling element of the support belt. The coupling element is a connection element that connects two free ends of the support belt together.

Abstract: An elevator system includes at least one autonomous unit for controlling an elevator and a multichannel-edge-gateway that builds communication between the autonomous unit and data resources on an IoT network. The multichannel-edge-gateway has more than one communication channel), wherein these communication channels provide data communicating using the same protocol or different protocols either synchronously or asynchronously. The multichannel-edge-gateway includes a channel assignment that automatically matches one of the communication channels to one of the protocols according to data to be sent from the multichannel-edge-gateway.

Abstract: An automatically controlled door arrangement, such as a floor door of an elevator installation, includes: at least one door leaf actively moveable between an open position and a closed position; a drive moving the door leaf between the open and closed positions; a controller controlling the drive; a sensor system detecting people or objects in front of the door leaf; and a data connection for data exchange with an external computer. The door arrangement receives and processes signals from the sensor system in the controller, sends query data to the external computer via the data connection based on the processed signals, receives instruction data from the external computer, and controls the door leaf drive taking into account the instruction data. The door arrangement provides monitorable, automated and, if possible, stepless access to buildings, for example, for robots, or receiving and storing delivered goods through the door arrangement.

Abstract: A building security system includes an emergency communications system of an elevator installation, and a building alarm system. The emergency communications system has a communications interface to couple the emergency communications system to a remote elevator service central in an emergency situation, and an emergency call panel arranged in an elevator car to allow a passenger to communicate with the remote elevator service central via the communications interface while in the elevator car during the emergency situation. The building alarm system includes a plurality of sensor units arranged at predetermined locations of the building and selected to detect predetermined building events.

Abstract: A control system for an elevator is separated into a first assembly allocated outside and a second assembly allocated inside an elevator shaft. The first assembly includes a power switch for turning on/off the control system, a light switch for switching a light inside the shaft, a safety unit for protecting electrical safety of the control system, a communication unit for data communication with the elevator and/or an external communication device, and a bypass device for bypassing a safety chain of the elevator. The second assembly includes a power supply system for driving the elevator and/or for the safety chain, a monitoring system for monitoring the safety chain, a drive control unit for a drive motor, and a processor for data processing of the control system. The first assembly and the second assembly can communicate with each other and be connected respectively as segments into the safety chain.

Abstract: An elevator car has a car body with movably mounted car door leaves having upper guide rollers and a roof frame which stabilizes the car body. In addition, there is a door drive for moving the car door leaves and a horizontal door guide rail for mounting and guiding the car door leaves. A door drive carrier is arranged on a horizontal surface on an upper face of the roof frame horizontally along an upper front horizontal edge of the car body. The door drive carrier has a vertical surface section which runs parallel to a vertical front side of the roof frame and a horizontal surface section which runs parallel to the horizontal surface of the roof frame. The guide rail is fastened directly to the vertical front side of the roof frame.

Abstract: An elevator system and a method for maintenance of such an elevator system include a device for receiving a plurality of sensor signals. The device is mounted on at least one elevator car or at least one counterweight of the elevator system. The device includes at least one processor and at least one computer-readable data store in at least one device housing. A first sensor for generating a sensor signal is a position sensor and/or a speed sensor and/or an acceleration sensor which is mounted in and/or on the device housing.

Abstract: An elevator comprises an elevator car, a counterweight, a drive and a support, wherein the support couples the elevator car and the counterweight with the drive so that the elevator car and the counterweight are movable in opposite vertical directions by the drive, and wherein the support has a support section at the car side and a support section at the counterweight side. The elevator further comprises a sensor line which is coupled to both the elevator car and the counterweight and which is guided so that in the case of movement of the elevator car and the counterweight in opposite directions it generally remains tensioned by a substantially constant tension stress. The elevator further comprises a sensor which is coupled with the sensor line so that slackening of a support section is detectable by the sensor.

Abstract: An elevator the drive unit is arranged laterally in a top section of an elevator shaft and, as seen from a shaft door opening, at a side wall of the elevator shaft. At least one cable is guided over deflecting rollers of a support frame of the elevator car and over deflecting rollers of the counterweight and serves as a support and drive cable for the elevator car or the counterweight. The cable is guided over a drive pulley of the drive unit and is arranged transversely to the side wall. The support frame is constructed as a rucksack frame with an upright frame guided by guide rails and a horizontal base frame on which the elevator car is arranged. On travel to the uppermost stopping point, the upper part of the elevator car travels past the drive unit.
