A security detection device for escalator, comprising a detecting circuit disposed on the inner side of the guardrails and for judging passengers, and the detecting circuit comprises a plurality of transmitting tubes disposed on the inner side of the guardrail, and a plurality of receiving tubes disposed on the inner side of the other guardrail, and the positions of the receiving tubes are one-to-one corresponding to the positions of the transmitting tubes; when light of the transmitting tubes is blocked by the passengers, and the receiving tubes generate an electrical signal, and after being recognized by the matrix recognition circuit, the signal is combined to form an image signal; after the detection interval time, receive a new image signal and compare it with the previous image signal, and when the difference exceeds the setting value, output a control signal to stop the motor, thereby stopping the moving of steps.

The present disclosure relates to systems and methods involving collapsible guardrails. An example system includes a top rail, a mid rail, an enclosure, and at least two posts. Each post includes an upper primary member, a lower primary member, an upper secondary member, and a lower secondary member. The upper primary member and the lower primary member are slidably coupled to at least one slot in the mid rail. The upper secondary member is rotatably coupled to the upper primary member and the lower secondary member is rotatably coupled to the lower primary member. The upper primary member is further coupled to the top rail and the lower primary member is coupled to the enclosure.

A transport device for conveying passengers between first and second landing areas in a conveying direction may include a skirt member and a balustrade, which may include lower and upper sides, extending between the landing areas. The skirt member may be secured to the lower side. An endless moving handrail may form a loop. A first section of the handrail moves along the upper side of the balustrade in the conveying direction, and a second section of the handrail moves within the skirt member opposite the conveying direction. Two turnaround sections are disposed between the first and second sections near the first and second landing areas, respectively. At least one of the turnaround sections includes a cover member that renders part of the turnaround section of the handrail inaccessible to passengers. The cover member may comprise a positioning mechanism for adjustably positioning the cover member relative to the balustrade.

A passenger conveyor has a guardrail belt configured to run on a pair of right and left handrails in synchronization with footsteps; a camera provided at a platform of the handrail; and a control device configured to analyze an image obtained by photographing the platform with the camera, detect a passenger getting in from the platform, stop the footsteps or lower a running speed than a normal speed when detecting no passenger for a predetermined time, and move the running speed of the footsteps at the normal speed when detecting the passenger.

An illustrative example device for installing portions of a passenger conveyor includes a base configured to be situated in a selected position on at least one of the passenger conveyor steps. A template supported on the base includes at least one balustrade position indicator situated at a preselected angle relative to the base. The balustrade position indicator defines an installation position for a balustrade supporting component of a passenger conveyor. The installation position establishes a lateral and vertical position of the balustrade supporting component relative to the at least one of the steps.

A passenger transport system having a conveyor belt is described. The passenger transport system comprises at least one handrail and a fastening device for a protective device in the region of the handrail end curve. A control unit blocks the operation of the passenger transport system in one direction of travel on the basis of a sensor signal, such that, if there is at least one protective device in the region of the handrail end curve, the direction of travel in which the handrail runs into the protective device is blocked. A method for controlling a bidirectional passenger transport system is also described.
