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.

A transport system which is suited for providing a number of person-transport services has a conveyor arrangement, a number of stationary stations and a controllable drive arrangement. A control unit system controls operation of the drive arrangement. The control unit system is configured to control a multitude of person-transport services which are requestable via an interface arrangement by non-touch, acoustical or electromagnetic signals. The number of such services is at least 50% of the person-transport services which may be provided by the transport system.

A support system supports the two ends of a passenger-transportation device in a built structure. The support system 6 has a swiveling support-point at a first end with a vertical swivel-axis. The second end contains a floating support-point for absorbing horizontal movements perpendicular to the swivel-axis. The floating support-point has at least one rolling element by means of which a sliding friction caused by the occurrence of horizontal movements in the floating support-point can be transformed into combined sliding-and-rolling friction or rolling friction.

A pallet conveyor (70), in particular a people conveyor, comprises a plurality of pallets (8) interconnected to form an endless pallet band which is moveable in a conveying direction, and a pallet chain (50) drivingly coupled to the pallet band. The pallet chain (50) comprises a plurality of pallet chain links (42; 44); the pitch of the pallet band is larger than the pitch of the pallet chain (50); and each pallet is (8) non-rotatably connected to or integrally formed with at least one of the pallet chain links (42; 44).

A passenger transport system includes a three-phase drive motor, a control device and an inverter module having power semiconductor switches. The gate electrodes of the power semiconductor switches are driven directly by the control device. The inverter module is connected on the input side to a DC source and on the output side to the three-phase drive motor. Between the DC source and the inverter module there is a DC circuit, wherein drive signals that can be modulated on the DC circuit can be generated by the control device, and the inverter module has a demodulator, by which demodulator the drive signals can be converted into control voltages assigned to the individual gate electrodes of the power semiconductor switches.

A drive chain (2a, 2b) for a chain drive comprises a plurality of chain links (10, 20) and joints (30) respectively connecting two of the chain links (10, 20) forming the drive chain (2a, 2b). The drive chain (2a, 2b) further comprises a plurality of carrier elements (40), each of said carrier elements (40) being linked to one of the chain links (10, 20) or joints (30) and supporting at least two support/engagement elements (43, 44), which are configured for supporting the drive chain (2a, 2b) and/or for engagement with an appropriate turnaround element (50; 90) for driving the drive chain (2a, 2b).
