Provided is a passenger-conveyor step-chain monitoring system capable of monitoring elongation of a step chain without adding a special device. The passenger-conveyor step-chain monitoring system includes a monitoring unit configured to monitor elongation of a step chain attached to a step of a passenger conveyor based on a result of detecting the step by a sensor provided to detect an absence of the step. With this configuration, it is possible to monitor elongation of the step chain without adding a special device.

A system for the safety of those installing escalator systems having structural supports. A hand-rail is utilized having at least one post, each post made of an upper portion and a lower portion. The upper portion contains a top rail slot and a bottom rail slot for a cable to pass through, the cable is tensioned at a cable tension mount which can be located along the side of the escalator structure or to the bottom ground surface or top ground surface. The lower portion of the post contains a bottom mount and mid-bottom mount, which mount to the side of the escalator structure at the desired location of the user. This hand-rail system eliminates the need for a worker to wear a safety harness and tether to a cable which restricts motion.

A conveyance element (20) for a people conveyor (1) is configured for being moved in a conveyance direction. The conveyance element (20) comprises a tread plate (24) configured for supporting passengers and at least one protection element (28, 29) configured for collecting items and/or fluids. The tread plate (24) has a longitudinal extension extending parallel to the conveyance direction and a lateral extension extending transversely to the conveyance direction. The at least one protection element (28, 29) is arranged below the tread plate (24), when the conveyance element (20) is arranged in an upright orientation, and it extends beyond at least one end (23) of the tread plate (24) in the conveyance direction.

The chain stretch detection device is configured to detect a stretch of a chain in a power transmission device. The power transmission device includes: a driving sprocket; a driven sprocket; and a chain, which is wound around the driving sprocket and the driven sprocket, and is configured to transmit power of the driving sprocket to the driven sprocket. The chain stretch detection device includes: a meshing height measurement device configured to measure meshing heights of the chain in a range in which the driven sprocket meshes with and the chain; and a signal processing device configured to determine a height difference between adjacent rollers in the chain through use of signals acquired by the meshing height measurement device and estimate an amount of the stretch of the chain based on the determined height difference.

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.
