Abstract: An apparatus for actuating a safety gear of an elevator includes a first stage actuation mechanism; and a second stage actuation mechanism. The second stage actuation mechanism includes a wedge arrangement configured to grip a guiderail associated with the elevator when the first stage actuation mechanism is triggered; a casing including the wedge arrangement and configured for vertical linear movement along the guiderail; and a transmission member coupled to the casing from a first end and to the safety gear from a second end. The apparatus is configured to cause the safety gear to actuate when the first stage actuation mechanism is triggered, the first stage actuation mechanism causing the wedge arrangement of the second stage actuation mechanism to grip the guiderail of the elevator and to decelerate vertical movement of the casing in relation to the guiderail, the deceleration of the casing causing the transmission member to engage the safety gear to the guiderail to stop the elevator.

Abstract: The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.

Abstract: A resetting device for resetting an actuator for actuating a safety gear of an elevator includes an actuation spring to be brought into a compressed state by a resetting force, an electric motor for providing the resetting force and a transmission for transmitting the resetting force of the electric motor to the actuation spring. The transmission provides a positive gear ratio.

Abstract: According to an aspect, there is provided an elevator parking brake comprising brake pads configured to provide a braking force against a guide rail in a loading and unloading situation of an elevator car; and at least one sensor. The elevator parking brake is configured to allow a predetermined amount of movement within the elevator parking brake in the loading and unloading situation of the elevator car, and the at least one sensor is configured to provide at least one indication associated with the movement within the elevator parking brake in the loading and unloading situation of the elevator car.

Abstract: An approach is provided for optimizing message routing without repeatedly resolving a home location. A login request from a user equipment associated with a resource identifier is received. The user equipment is configured to operate within a network including a plurality of clusters. The resource identifier of the user equipment is modified to include home cluster information indicating a corresponding one of the clusters serving the user equipment.

Abstract: An approach is provided for message routing among clusters via a proxy channel. A subscription request is received from a node within a local cluster. The subscription request is for a service. It is determined that the service is provided by a remote cluster. A transmission of the subscription request to a service platform of the remote cluster is initiated. The service is provided to the node via a proxy channel.
