Abstract

A device for reducing an actuation force spike in an elevator car safety system. The device includes an elevator car mounted overspeed governor a safety gear a safety lever and a force reducing mechanism. The force reducing mechanism is connected in a series relationship with the safety lever between the overspeed governor and the safety gear.
