Elevator access systems having an access control module operably connected to an elevator system and an access device located within the access control module and removable therefrom, wherein when the access device is within the access control module a normal mode of operation of the elevator system is activated and when the access device is removed from the access control module, the elevator system enters a safety mode of operation.

A compensation guide, counterweight screen, traction elevator and method for guiding a compensation element are disclosed. The compensation guide includes a horizontally directed guide opening through which the compensation guide passes. The guide is mounted vertically movably to the counterweight screen.

An elevator system 2 is provided which comprises: a hoistway 6 accessible by at least one hoistway door 10a, 10b, 10c; at least one elevator car 4 located in the hoistway 6; a hoistway door switch 12a, 12b, 12c associated with the at least one hoistway door 10a, 10b, 10c; at least one inspection switch 16; at least one emergency stop switch 18; and an elevator controller 24. The elevator controller 24 is configured to monitor the hoistway door switch 12a, 12b, 12c, the inspection switch 16 and the emergency stop switch 18 and to prevent inspection mode operation of the elevator car 4 until at least one change of state is detected of each of the hoistway door switch 12a, 12b, 12c, the inspection switch 16 and the emergency stop switch 18.

An unlocking device with an actuator releases a safety cover of a maintenance opening for opening. The locking device has a safety circuit for actuating the actuator. The safety circuit includes at least one first switching contact and a second switching contact arranged in series, wherein the actuator in a closed state of the first and the second switching contacts is connected by the safety circuit with a power source, and the first switching contact can be switched by a control unit. One or more of the unlocking device can be used in an elevator system.

An elevator door bypass apparatus, configured to bypass a landing door or a car door at a time of an inspection of an elevator, includes: a door mode selector switch configured to switch a door mode between a normal operation and a bypass operation; a bypass target selector switch configured to switch between bypassing of the landing door and bypassing of the car door; and a bypass relay configured to, in a case that the door mode has been switched to the bypass operation by the door mode selector switch, bypass the landing door when the bypassing of the landing door has been selected by the bypass target selector switch, and bypass the car door when the bypassing of the car door has been selected by the bypass target selector switch.

A compensation guide, counterweight screen, traction elevator and method for guiding a compensation element are disclosed. The compensation guide includes a horizontally directed guide opening through which the compensation guide passes. The guide is mounted vertically movably to the counterweight screen.

Disclosed is a motion detection device for monitoring movement of a component comprising a housing removably connectable to the component; an indicator arranged within the housing, the indicator being operable to indicate movement of the component; at least one sensor arranged within the housing, the at least one sensor configured to sense data in response to a gravitational force acting thereon; and a controller operably coupled to the at least one sensor and the indicator, the controller including an algorithm configured to determine when the motion detection device is moving and to operate the indicator when the motion detection device is moving.

A fault diagnosis method, a readable storage medium, an electronic device and a fault diagnosis system for interaction between an elevator system and a machine passenger. The fault diagnosis method for diagnosing a fault in the interaction between the machine passenger and the elevator system via the interaction management apparatus includes: acquiring diagnostic information from the elevator system and the interaction management apparatus; simulating an interaction process between the machine passenger and the elevator system via the interaction management apparatus based on the acquired diagnostic information; and judging a fault type of interaction between the machine passenger and the elevator system based on the simulated interaction process.

According to an aspect, a method includes detecting, by a computing system, whether there are any pre-existing objects between a first group of sensors of a sensor array in an elevator shaft. The computing system detects whether there is a foreign object between a second group of sensors of the sensor array in the elevator shaft, where the second group of sensors includes at least one sensor that differs from the first group of sensors. The computing system triggers a modification to a control aspect of an elevator car in the elevator shaft based on detection of the foreign object.

An elevator system (1) comprises: a hoistway (4) extending between a plurality of landings (8, 9); at least one hoistway door (10, 11) allowing access to the hoistway (4); an elevator car (6), which is configured to move along the hoistway (4); at least one safety (16), which is attached to the elevator car (6) and configured to stop any movement of the elevator car (6) when activated; an electronic safety actuator (18), which is configured to activate and deactivate the at least one safety (16); and a door safety switch (20), which is configured to monitor the at least one hoistway door (10, 11) and which is connected with the electronic safety actuator in order to allow activating the at least one safety (16), if the door safety switch (20) detects that the at least one hoistway door (10, 11) is not closed.
