Method and appliance for tripping the safety gear of an elevator using an overspeed governor

Abstract

A method for tripping safety gear of an elevator, at a speed lower than a gripping speed of the elevator may include: slowing a rope sheave of an overspeed governor of the elevator using a device adapted to slow the rope sheave; disconnecting an actuator connected to the overspeed governor from movement of the rope sheave when the device slows the rope sheave; and tripping the safety gear in an overspeed situation using a rope driving the overspeed governor via the rope sheave. An appliance for tripping safety gear of an elevator may include: an overspeed governor; a rope sheave of the overspeed governor; a device adapted to slow the rope sheave; and an actuator connected to the overspeed governor that is arranged to disconnect from movement of the rope sheave when the device adapted to slow the rope sheave acts to slow the movement of the rope sheave.
