Counterweights for elevator systems are described. The counterweights include a frame and a counterweight safety system attached to the frame. The safety system includes a safety brake mounted to an upright of the frame and configured to enable engagement with a guide rail to apply a braking force. A sheave is mounted to the frame and configured to operably connect to tension members. The sheave is configured to move between a first position when under tension and a second position when the tension is lost. A connecting link operably connects the sheave to the safety brake. The connecting link has first and second link members operably connected between the sheave and the safety brake.
