Abstract
An overspeed brake system is described to engage a safety cable and subsequent brake system once a threshold speed is reached. An overspeed safety kit may be installed on an elevator system or lift car, to identify a threshold speed and engage a brake lever to activate a braking system. One or more brake engagement devices may be applied to limit the force on the brake lever during a fall, thereby preventing potential damage to brake components, while cushioning the deceleration.
