An elevator counterweight assembly (11) comprises a counterweight structure (38), , at least one safety brake (12a, 12b) mounted on the counterweight structure (38), and a safety actuation mechanism (16) comprising a connection (17) for a suspension member (18). The safety actuation mechanism (16) is configured to move, relative to the counterweight structure (38), between a normal position, and a safety position. In the safety position the safety actuation mechanism (16) is arranged to actuate the at least one safety brake (12a, 12b) and thereby brake the counterweight structure (38). The counterweight assembly (11) also comprises a mechanical actuator (22), configured, when actuated, to apply a force to the safety actuation mechanism (16) and thereby move the safety actuation mechanism (16) from the normal position to the safety position, e.g. for the purposes of a handover test.
