Power is recovered from an escalator or a moving walkway as the step orbits an endless track on rollers. A generator is connected to a roller orbiting the track. A battery backup is provided. The power is used for emergency lighting on the step, and for data transmission. Advertising and messages are displayed on a dynamic video screen mounted on the step. The apparatus is mostly contained within the escalator step. Information is communicated wirelessly to a remotely located central control station and back to the step, so as to display information in real time and to update advertising while the escalator is in operation. The central control station also monitors performance parameters. The visual display can include LED lighting.

A pair of displacement restricting members are fixed to a support member. When the support member is viewed from above, the displacement restricting members include reference end portions, respectively, which are positioned on a setting straight line set on an upper surface of the support member. The pair of displacement restricting members is fixed to the upper surface of the support member so that the reference end portions are directed in directions opposite to each other in a direction along the setting straight line. The end portion of the truss includes a pair of abutment surfaces facing the reference end portions, respectively. A gap is present in at least any one of a region between the reference end portion of one displacement restricting member and one abutment surface and a region between the reference end portion of the other displacement restricting member and the other abutment surface.

A track module of an escalator or a moving walkway comprises at least two support structures and at least one guide rail. Each support structure includes at least two supports and at least one cross strut, wherein the cross strut is arranged between the at least two supports and connects these together. Each support has a foot fastening region which, in the installed state, is fastened to a carrying structure. Moreover, a balustrade fastening region, to which in the installed state at least a part of a balustrade is fastened, is formed at each support, so that static and dynamic loads acting on the balustrade are transmissible directly to the carrying structure by way of the supports.

An escalator system includes a pit having an access cover plate, a detector indicating when the access cover plate is open and when it is closed, and a user interface which is located in said pit and which in an active state provides the escalator system with control signals controlling the operation of the escalator and which in a passive state does not affect the operation of the escalator. In order to improve the safety of the escalator system the escalator system is configured to stop movement of the escalator if the detector indicates that the access cover plate is closed while the user interface is in the active state.

A truss section (2, 3, 4), which is configured to support at least one tread element in a passenger area (30) of a passenger conveyor (15) of the type conveying passengers by moving the at least one tread element in a longitudinal direction along the passenger area (30) between a first landing and a second landing, comprises at least two longitudinal elements (5a, 5b) extending basically parallel to each other in the longitudinal direction; and at least one lateral connector (6) connecting the at least two longitudinal elements (5a, 5b). Each of the at least two longitudinal elements (5a, 5b) includes at least one load-bearing portion (51, 52, 53) having the configuration of a single wall profile.

An escalator with a step belt or a moving walkway with a plate belt has a first deflecting region and a second deflecting region, wherein the plate belt or the step belt is arranged to circulate between the first deflecting region and the second deflecting region. The escalator or the moving walkway includes at least one guide rail arranged between the deflecting regions for guidance of the step belt or the plate belt, as well as at least one support, which is arranged between the deflecting regions for supporting the at least one guide rail. The at least one support includes a plurality of plug parts that in an assembled state can be plugged together by plug connections to form a box-shaped support base body.
