Elevator systems utilize safety mechanisms with brakes that engage guide rails when an elevator car limit speed is exceeded or when a free-fall condition is detected. A device may be employed in such elevator systems to simultaneously activate the safety mechanisms and vastly decrease the likelihood that failure of the members connecting one safety mechanism will render other safety mechanisms inoperative. The device may generally include a rotatable central member that is configured to be coupled to a governor assembly of an elevator system. The device may also generally include linkages that connect the central member in parallel to the safety mechanisms. When the governor assembly is activated and exerts an activation force at the central member, the central member rotates to simultaneously activate the safety mechanisms and engage brakes of the safety mechanisms with the guide rails.
