[0002] The elevator speed governor is a device for speed response and operating safety clamps. When the running speed of the elevator car reaches a limit value, the speed governor can send an electrical signal and produce a mechanical action, thereby triggering the safety clamps to work and stopping the running of the elevator car. It is an important protection device for the elevator in dangerous situations such as overspeed, running out of control or suspension device rupture. The speed governor of the machine room elevator is usually installed in the machine room, and the speed governor of the elevator without machine room is generally installed at the top of the shaft.
