Overspeed governor is one of the safety control units of elevator safety protection system. During running, when the car over-speed or even risk to fall while other protection devices do not work, the over-speed governor and safety gear or up-going protective device will generate linkage protection to stop the car. Governor generally be installed inside the elevator machine room or directly installed on the bearing beam, machine roomless governor will be installed on the guide rail or bottom hole on the ground.

(For details, pls study the corresponding type test report) to ensure its performance matching with the elevator actual state.
