A passenger conveyor system and an anti-collision device for step and comb plate. The passenger conveyor system includes a step chain having a plurality of steps, a comb plate and an anti-collision device, the anti-collision device includes an actuating mechanism connected to the comb plate and configured to, when a moving distance of a step adjacent to comb teeth of the comb plate to be engaged in a vertical upward direction of the passenger conveyor system exceeds a preset value, actuate the comb plate to be lifted up from an initial first position to a second position to avoid collision with the step; and a reset mechanism configured to return the comb plate from the second position to the first position after the step travels through the comb plate.

An escalator system is provided and includes a combplate including teeth, a moving step including grooves and being drivable to pass by the combplate at a step-combplate interface at which, when each tooth is correctly positioned, each tooth passes through a corresponding groove and a detection system. The detection system includes an emitter and receiver pair and is configured to determine whether a signal pattern, which is derived from communications of the emitter and receiver pair and which is partially reflective of conditions of the teeth, is indicative of at least one tooth being incorrectly positioned.

A dynamic comb for use with a conveyance system to transition a passenger or object from a nonmoving element to a moving element and vice versa. The dynamic comb can include a upper support element or a lower support element. The dynamic comb can also include a roller element disposed at least partially between and below portions of the upper support element. A method of installing the dynamic comb for an existing conveyance system or as part of a new conveyance system to transition a passenger or object from a nonmoving element to a nonmoving element and vice versa.
