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.
