This application relates to a method and an apparatus for monitoring a state of a passenger transport system such as, for example, an escalator. The method includes monitoring the state of the passenger transport system using an updated digital double data record that reflects characterizing properties of components of the passenger transport system in an actual configuration of the passenger transport system in a machine-processable manner after the assembly and installation thereof in a building. The updated digital double data record can be obtained, for example, by accurately surveying the passenger transport system and using signal values from sensors housed in the passenger transport system, and allows conclusions as to the present or future state of the passenger transport system, based on which maintenance measures can be planned efficiently and adequately.

The invention relates to a method for determining an access right to an entity of a conveyor system, wherein it is: received data comprising data representing an identity of a wireless key and data representing a location of the wireless key; detected that the wireless key resides in a predefined location; identified the conveyor system and the entity on a basis of data representing the predefined location; determined status of an identified conveyor system; determined an access right with the wireless key to the entity; and generated a control signal to cause one of the following: (i) a grant of an access to the entity, (ii) a refusal of an access to the entity. The invention also relates to a network node, a computer program product and to a conveyor system.

An elevator car includes a roof deck; a plurality of walls; a floor; one or more doors; and a transport space bordered by the roof deck, the plurality of walls, the floor, and at least one openable and closable door for allowing access to said transport space. The roof deck is vertically movable from a first normal use position upwards to a second cargo use position for increasing the height of the transport space, and from the second position downwards back to the first position for reducing the height of the transport space. An elevator and a method implementing the elevator car are also disclosed.

A remote triggering device, an overspeed governor assembly and an elevator system are provided. The remote triggering device includes: an actuator seat mounted on a fixed bracket and rotatable between a first position and a second position; an actuator disposed on the actuator seat and having an action end movable between a retracted position and an extended position; and a reset lever extending from the actuator seat; wherein in a case that the centrifugal mechanism of the overspeed governor assembly rotates in a first direction corresponding to ascending of an elevator car, when the action end of the actuator moves to the extended position, the centrifugal mechanism of the overspeed governor assembly contacts the action end of the actuator and drives the actuator seat to rotate from the first position toward the second position, and the reset lever rotates with the actuator seat.

The present disclosure relates generally to a limit switch system for an elevator. The limit switch system includes a limit device configured to determine a position of the elevator car at a location of the hoistway upon selection of an inspection state.

A control device controls an elevator system in inspection mode, the elevator system having a safety circuit with at least one safety contact that is open in inspection mode and an inspection path for bridging the safety contact. The control device includes first and second operating elements for controlling the inspection mode and first and second switching units connected in parallel and each having a contact associated with a delay means. The switching units close and open their contacts in response to actuation and release of the first and second operating elements respectively. The contacts are series connected in the inspection path. The first and second delay means delay opening of the associated contacts by defined delay times after the release of the first and operating element respectively.

The invention relates to an elevator arrangement comprising an elevator with a control system, and an inspection or maintenance mode, which elevator further comprises an elevator car arranged to run up and down in an elevator shaft along its guide rails, and which elevator car is equipped with a roof and a car operating panel. The arrangement comprises actuating means to open the roof of the elevator car, which actuating means are operatively connected to the car operating panel of the elevator.

An elevator inspection and maintenance system, the system including a mechatronic body movable via remote or automatic operation, an inspection and maintenance head installed on the mechatronic body, where the inspection and maintenance head is fitted with a sensor or a manipulation tool to perform an inspection or a maintenance operation on at least one component of an elevator system remotely or automatically.

Disclosed is an elevator inspection system, having: a sensor implement; a robotic platform supporting the sensor, the robotic platform configured to inspect a hoistway; a controller operationally connected to the robotic platform and the sensor, wherein the controller is configured to define hoistway model data for the hoistway, from sensor data, corresponding to locations and shape boundaries of the hoistway and doorway openings formed in the hoistway.

A door lintel assembly for an elevator, and an elevator system. The door lintel assembly includes: a door lintel panel having an opening thereon; a display device, which is installed on the door lintel panel via the opening, and which has a display screen on a first side of the door lintel panel, and electronic components on a second side of the door lintel panel; and a rotation device, which includes a first bracket installed on both sides of the door lintel panel, a second bracket fixedly installed, and a rotation mechanism connecting the first bracket and the second bracket, wherein the rotation mechanism drives the first bracket and the door lintel panel to rotate relative to the second bracket.
