An assembled passenger conveying system, a method of assembling the same and a modularized device. The assembled passenger conveying system includes at least two modularized devices, the at least two modularized devices are detachably connected to form a loading area, and power is supplied from one or more modularized devices to drive the loading area to travel on a conveying path of the assembled passenger conveying system.

In the step for a passenger conveyor, a sleeve includes a sleeve main body, which has a tubular shape and is slidable with respect to a main shaft portion along an axis line of the step shaft, a claw to be hooked to a level-difference portion formed at a boundary between the main shaft portion and a projecting shaft portion, and a connecting portion configured to connect the sleeve main body and the claw. The connecting portion includes an arm portion which is elastically deformable in a direction in which the claw is unhooked from the level-difference portion. A mounting portion, having a recessed portion formed therein, is fixed to the step main body. The recessed portion is fitted over an outer peripheral surface of the sleeve main body. An open portion of the recessed portion is smaller than an outer diameter of the sleeve main body.

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.

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.

A conveyor device (2) comprises a truss (4); a conveyance element (8), which is movable with respect to the truss (4) in a longitudinal direction and which comprises at least one groove (22) extending along said longitudinal direction. The conveyor device (2) further comprises a comb plate (16) having at least one tooth (18) extending into the at least one groove (22). For minimizing the effects resulting from a comb crash, the conveyor device (2) further comprises at least one compensation device (24, 26, 28a, 28b) fixing the comb plate (16) in the longitudinal direction during normal operation, but allowing the comb plate (16) to move in the longitudinal direction in case of a comb crash.
