A carrier component for a track system may comprise a carrier and a pair of rollers coupled to one another by the carrier. Each of the rollers may include at least one rolling surface configured to engage opposing sides of a track. At least one of the rollers may be spring-loaded and biased toward the other. Alternatively, or additionally, at least one spring loaded roller may include an armature connected to a pivot of the carrier, wherein the armature may be biased by a coil spring for coupling the at least one spring loaded roller with a track.

Conveyors and people movers, such as escalators and moving walkways, for instance, may include a support member belt comprised of a plurality of support members guided on rails. The support members may be, for example, steps of an escalator or pallets of a moving walkway. Each support member may be secured to a pair of drag rollers that travels along the rails. Further, each support member may include a roller spindle that is held rotationally conjointly in or on a body of the support member. Between the roller spindle and the body of the support member, there may be a plug-in connection by way of which the roller spindle is maintained against an undercut under bias of a latching device.

The application relates to passenger transport systems and related methods. The passenger transport system has multiple step units, a comb plate, a monitoring device, and a marking device. The step units are to be moved one behind the other continuously along a predefined movement path during normal operation. The comb plate is arranged at a fixed position relative to the predefined movement path. The monitoring device is configured to monitor an actual position of a currently monitored step unit relative to the predefined movement path and to detect a deviation of the actual position from the predefined movement path by more than an allowable tolerance value and activate the marking device in response thereto. Upon being activated, the marking device is configured to mark the currently monitored step unit and/or a step unit spatially correlating to the currently monitored step unit.

The embodiments herein provide an automatic non-conveyor stairway comprising two separate straight stair flights that move inside each other without interference. One stair flights moves horizontally. The other stair flight moves vertically. With discrete sequential motion of the stair flights, an arbitrary load is transferred along the stairway. Each stair flights includes several comb-teeth shaped stair steps. The stair steps of horizontal stair flights comprises parallel plates along the stair width attached to a supporting wall at the back. The vertical stair flights include parallel plates fixed at the bottom to a supporting base. The supporting bases are connected to stringer at the left side of the stairs. The supporting walls are fixed to another stringer at the right side. The stringers are confined to move horizontally and vertically, thereby providing the required motion of the stair flights.
