ABSTRACT:
Disclosed is a system for engaging safeties on an elevator car. The system comprising a contact surface in a hoistway and a safety tripping lever pivotally mounted on an elevator car. Upon contact by the lever with the contact surface, the safeties engage, with the contact surface preventing the safeties from disengaging until the car comes to a stop. A feature of the system for engaging safeties on an elevator car is the ability of a portion of the safety tripping lever to retract away from the contact surface upon movement of the elevator car in a direction opposite of the car's braking direction, wherein the retraction of the lever facilitates the disengagement of the safeties.
