A people conveyor (10) comprises: a chain of conveyance elements (12), which are configured for conveying people; a drive unit (14), which is configured for driving the chain of conveyance elements (12); and a self-locking gear (20; 40), which is configured to lock when no torque is transmitted from the drive unit (14) to the chain of conveyance elements (12).

An elevator system is provided. Aspects includes at least one elevator car and a camera affixed to the at least one elevator car, wherein the camera is operated by a controller. The controller is configured to automatically capture, from the camera, media associated with a set of locations, wherein the set of locations are associated with the at least one elevator car. A transceiver transmits one or more sequences of the media captured from the camera.

A tread element (12) for a passenger conveyor (10); the tread element (12) comprising a tread (14) defined by a front side, a rear side, a first lateral side and a second lateral side; a riser (16) comprising a riser panel (18) adjacent the rear side of the tread (14) and pivotably connected to the tread (14); at least one tread chain axle (28) adapted to connect the tread element (12) to the at least one tread chain (22); at least one tread roller (42) adapted to engage with a guide element (36) of the passenger conveyor (10) to adjust the position of the tread (14) with respect to the riser (16); and at least one cantilever arm (40) supported at its one longitudinal side by the tread chain axle (28) and supporting the tread roller (42) at its opposite longitudinal side.

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.

The invention relates to a handrail system of a people mover, the handrail system comprising a circulating handrail and a safety system of a handrail inlet in a handrail housing. The safety system comprises a hatch provided around the handrail inlet in the handrail housing; and trigger means operationally connected between the hatch and the handrail housing to launch the hatch from a first position inwards into the handrail housing to a second position in response to a detection of an object touching the hatch or arriving to a safety area in front of the hatch. The handrail system further comprises a coupling for operatively connecting the circulating handrail and the safety system, the coupling being arranged to stop the handrail in response to the launch of the hatch inwards into the handrail housing or in response to a detection of an object by a sensor which the object is arriving to the safety area in front of the hatch. The invention further relates to method for preventing injuries in a handrail system of a people mover. The method comprises the steps of providing a hatch around a handrail inlet in a handrail housing of a circulating handrail; operationally connecting the hatch, the handrail housing and the handrail; launching the hatch from a first position inwards into the handrail housing to a second position in response to a detection of an object touching the hatch or arriving to a safety area in front of the hatch; and stopping the handrail in response to the launch of the hatch inwards into the handrail housing or in response to a detection of an object by a sensor which the object is arriving to the safety area in front of the hatch.

The present invention relates to the field of passenger conveyor technologies, and provides a monitoring system of a passenger conveyor and a monitoring method thereof. In the monitoring system and detection method of the present invention, a monitored object of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor to acquire a data frame, and the data frame is analyzed by a processing apparatus to monitor whether the monitored object is in a normal state. The monitored object may include a landing plate, a step, a barrier used in a maintenance and repair working condition and/or a step speed, and the like.
