Abstract

Elevator systems include a traveling component (306) and a guide rail (308) within an elevator shaft. An overspeed safety system (300) is operably connected to the traveling component and includes a brake assembly (304) and an actuator assembly (302). A trigger element (320) is configured to release stored energy of a stored energy device (328) to cause engagement of a safety brake element (310) with the guide rail (308) to stop downward travel of the traveling component. When the safety brake element (310) is engaged with the guide rail (308), upward motion of the traveling component causes the safety brake element (310) to disengage from the guide rail (308) and return the stored energy device (328) to a state of stored energy.
