Abstract: A drive system for transport of a passenger transport installation including an escalator or a moving walkway. Steps or pallets of the transport are actively connected to pulling elements which can be moved in the transport direction by at least one electric motor provided with a gear train having a chain wheel. The electric motor containing the gear train is positioned in one of the reversing areas of the transport and a further electric motor exclusively serves for the linear motion of the transport. Bushes/rolls of plate link chains are adjacent to or roll along individual teeth of the chain wheel while only getting into line contact, outside the tooth ground of the chain wheel. A point of force application of the bushes/rolls on the respective tooth of the chain wheel is realized such that only a one-directional force application component is generated at the respective tooth.

Abstract: A device for connecting a chain, which is actively connected to a roller, to a step or a pallet of an escalator or a moving walkway, respectively. The chain has a roller side and a step or pallet side. The device includes a hollow stud disposed on the roller side and a cylindrical shoulder disposed on the step or pallet side. The hollow stud has a clearance to receive the cylindrical shoulder. A slide bearing is arranged at least radially between a circumferential surface of the hollow stud defining the clearance and an outer circumferential surface of the shoulder.

Abstract: A method for controlling an installation for a revolving passenger transport comprised of steps or pallets moving along a transport path that includes a plurality of drives. At least one drive is arranged in a reversing area and at least one further drive is arranged in an area of the transport path. Each drive is actively connected to a frequency converter. All of the frequency converters are monitored by a higher-order control. A defined drive pattern is memorized in the higher-order control. Measured values of the drives are transmitted to the higher-order control by individual frequency converters. The measured values are compared in the higher-order control with respect to each other. In case of divergences from the memorized drive pattern of the respective frequency converter, the respective frequency converter which diverges from a comparative value is corrected with aid of the higher-order control.

Abstract: Device for the passenger transport, in particular an escalator provided with steps or a moving walkway equipped with pallets, wherein the steps or pallets are connected to each other to form a continuous step or pallet belt and can be moved in the direction of transport by means of drive elements, wherein a lower entrance or exit section of the device is connected to an upper exit or entrance section via at least one arched transport section which, seen over the length and height thereof, is formed by different radii which verge into each other, wherein at least the arched transport section is composed of several linear framing sections which are connected to each other in the region of the facing ends thereof.

Abstract: A method and arrangement for controlling the respective brake of a device for transporting people, such as an escalator or a moving pavement in that the control signals for the drive motors and the brake are monitored with the aid of several processors. If functional interruptions occur in the region of the device for transporting people, the brake is applied abruptly. If deceleration values are detected, the brake is relieved in a defined manner and the device for transporting people is thus stopped via the processors within a predetermined time interval.

Abstract: A method and a system for disconnecting passenger transport systems, especially escalators and moving walkways. Functional units of a passenger transport system monitor for malfunctions of the passenger transport systems by using switching elements and the signals of the functional units are combined to form a security chain. The signals of the functional units and signals from a drive monitoring unit are supplied to at least one pilot unit. Subsequently, a disconnecting signal is provided to a respective disconnecting contact as a result of a malfunction detected by the functional units and/or the drive monitoring system.

Abstract: A device for monitoring the presence. of steps and pallets of an escalator or moving walkway, such that missing steps or pallets are immediately detected, so that the drive will be stopped before the missing or defective part reaches the visible area of the escalator or moving walkway.

Abstract: A switching arrangement for returning a people-conveying device to a state of readiness comprises a plurality of light barriers which are formed by emitters and receivers and whose signals are fed to at least one electronic evaluation device, which automatically returns the people-conveying device to a state in which it is ready for use after an emergency off switch has been activated. The individual emitters and receivers are combined to form a light barrier chain and are disposed approximately opposite one another at predetermined spacings. Emitters and receivers are provided alternately on each side of the people-conveying device. The wiring between individual emitters and receivers on each side of the people-conveying device is brought about by plug-in connections without any connections to the emitters and receivers on the opposite side.
