  • Publication number: 20230032978
    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.

  • Patent number: 11459208
    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.

  • Patent number: 10508002
    Abstract: A rope lifting tool for belt-shaped ropes comprises a first guide for guiding the rope lifting tool along a first guide rail; a second guide for guiding the rope lifting tool along a second guide rail; an upright plate, and an inclined plate at an acute angle relative to the upright plate. The upright plate and the inclined plate have a wedge shaped space between them. A plurality of wedge members are placed adjacent each other inside the wedge-shaped space. A rope gap for receiving an end of a belt-shaped rope is formed between each wedge member and the upright plate, which rope gap is narrowable by wedging of the wedge member in the wedge shaped space. A rope lifting arrangement includes the rope lifting tool.
