A mechanical hoistway access control device for an elevator landing door includes a first and a second base plates mounted on the hoistway side of a landing door panel and arranged in parallel with one another, a slider slidably arranged between the first and second base plates and configured to move in conjunction with a car door and configured to protrude out from a door closing side end of the landing door by a first elastic member to take an extended position when the landing door is opened with no elevator car at the landing, and a latch attached to the landing door and configured to engage with the slider to keep the slider in the extended position once the slider protrudes out from the door closing side end of the landing door.

A blocking device (2) for blocking access to an door unlocking device (118) of an elevator system (102) comprises: an outer element (4), which is introducable into an access opening (30) providing access to the door unlocking device (118); and an inner element (6), which is introducable into the outer element (4). The inner element (6) is configured for bringing the blocking device (2) into a fixing configuration, in which the outer element (4) is fixedly engaged with the access opening (30), by introducing the inner element (6) into the outer element (4).

Elevator maintenance space projection systems and elevator systems including a projector located within an elevator shaft and arranged to project a display space within the elevator shaft such that the display space includes one or more projected images identifying at least one of a safety volume, a refuge space, and a maintenance location.

Elevator lintel door lock safety devices having a frame mountable to a lintel, a lintel door lock fixed to the frame and having a first lock element rotatable relative to a second lock element, a contact plate fixed to the first lock element and moveable therewith, the contact plate having at least one contact attached thereto, a contact receiver attached to the frame and part of a safety chain, the contact receiver having at least one contact receiver aperture arranged to receive a respective contact of the contact plate, and a blocking element pivotably mounted to the frame wherein a portion of the blocking element is moveable between (i) a first position to prevent the at least one contact from engaging with a respective contact receiver aperture and (ii) a second position that allows the at least one contact to engage with the respective contact receiver aperture.

An elevator system includes a counterweight and an elevator car supported by support device and moved in opposite directions in an elevator shaft. In an operating method for operating the elevator system, the elevator car approaches the counterweight and/or moves past the counterweight in an approach zone in the elevator shaft, and the elevator car moves at a first speed outside of the approach zone and at a second speed in the approach zone, the second speed being lower than the first speed.

According to an aspect, there is provided a method for controlling an elevator system. The method comprises causing transmission of radio frequency signals with at least one radio frequency sensor attached to at least one element movable in an elevator shaft of an elevator system, receiving, from the at least one radio frequency sensor measurement data representing radio frequency signals reflected from at least one object and captured with the at least one radio frequency sensor, causing identification, based on the measurement data, of at least one object; and controlling operation of the elevator system in response to identifying the at least one object based on the measurement data.

The invention relates to a method for resetting a safety mode of an elevator system. The safety mode is caused by a power cycle of the elevator system. The method comprises: obtaining, upon a restoration of a power supply of the elevator system, status information indicative of a current safety status of at least one safety space of the elevator system from an elevator safety detection system; receiving, from a remote elevator service entity, a reset command comprising an instruction to reset the safety mode of the elevator system; and resetting the safety mode of the elevator system in response to receiving the reset command, if the obtained status information fulfills a predefined criterion. The invention relates also to an elevator safety control unit, a remote reset system, a computer program, and a computer-readable storage medium for resetting a safety mode of an elevator system.

A monitoring unit, for monitoring an elevator system, includes a circuit assembly having a power supply unit for dispensing a grid-dependent first operating voltage and at least one processor-controlled monitoring module to actively and/or passively ascertain state data of the elevator system. An energy storage unit, that dispenses a grid-independent second operating voltage, and a first switching device supply the first operating voltage to the monitoring module during a normal operation and supply the second operating voltage to the monitoring module in the event of a power outage. A non-volatile data storage unit that stores a variable operating parameter and a second switching device deactivate parts of the circuit assembly. The monitoring module actuates the second switching device based on the stored operating parameter that has a first value before the monitoring unit is started and has a second value after the monitoring unit is started.

The elevator comprising a car moving upwards and downwards in a well, a controller controlling the elevator, and a well lighting. The method comprises detecting an activation of a well access operation mode of the elevator, activating the well lighting automatically when the controller detects that the well access operation mode of the elevator has been activated.

Elevator overrun systems having a first body arranged to be fixedly mounted to a portion of an elevator system or elevator shaft, a second body positioned within the first body and moveable from a deployed state to a retracted state relative to the first body, and a limit switch located at a distal end of the second body, the limit switch configured to interact with a component of an elevator system to prevent movement of an elevator car.
