According to an aspect, there is provided an apparatus (100) for actuating a safety gear (122) of an elevator. The apparatus (100) comprises a first stage actuation mechanism (108); and a second stage actuation mechanism comprising a wedge arrangement (102, 104) configured to grip a guiderail (4) associated with the elevator when the first stage actuation mechanism (108) is triggered; a casing (118) comprising the wedge arrangement (124, 126) and configured for vertical linear movement along the guiderail (120); and a transmission member (106) coupled to the casing (118) from a first end and to the safety gear (122) from a second end. The apparatus (100) is configured to cause the safety gear (122) to actuate when the first stage actuation mechanism (108) is triggered, the first stage actuation mechanism (108) causing the wedge arrangement (102, 104) of the second stage actuation mechanism to grip the guiderail (120) of the elevator and to decelerate vertical movement of the casing (118) in relation to the guiderail (120), the deceleration of the casing (118) causing the transmission member (106) to engage the safety gear (122) to the guiderail (120) to stop the elevator.
