An access control arrangement of a conveyor system, a mobile device, a conveyor system, and a method for controlling access in a conveyor system are disclosed. The conveyor system includes a manual key-operated access mechanism operable via a key-hole by a key. The access control arrangement includes a communication device for communicating with a mobile device, and a blocking member configured to cover the keyhole in a first position for blocking external access, and to expose the keyhole in a second position, the blocking member being movable between the first and the second positions. The access control arrangement is configured to lock the blocking member in the first position, and release it from the first position in response to receiving a release signal by the communication device.

Elevator systems and methods including an elevator car within an elevator shaft, at least one component subject to inspection, the at least one component having an indicator element thereon, and an inspection system comprising a detector located on the elevator car and arranged to detect the presence of the indicator element in a detection region such that when the indicator element is detected within the detection region, a notification regarding a state of operation of the at least one component is generated.

A device for unlocking a landing door includes a door leaf that can be moved between an open position and a closed position, a bar arranged on the door leaf to lock the door leaf in the closed position, and an energy accumulator coupled to the door leaf to provide the energy for moving the door leaf into the closed position in the event that the energy supply needed to drive the door leaf fails. The energy accumulator is coupled to the door leaf by an elastic element such that through a displacement of the energy accumulator when the door leaf is in the closed position, the bar is moved to an unlocked position.

A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

Elevator access systems and methods including a key extension having a first portion arranged to engage with a key and a second portion and an access mechanism. The access mechanism includes an extension engagement element arranged to receive and fixedly engage with the second portion of the key extension and an opening element operably connected to the extension engagement element such that operation of the extension engagement element causes operation of the opening element.
