Abstract:
An exemplary elevator system includes an elevator car. A first governor sheave is supported on the elevator car for movement with the elevator car. The first governor sheave is supported for rotational movement relative to the elevator car responsive to movement of the elevator car. A first governor tripping mechanism is supported on the first governor sheave. The first governor tripping mechanism provides an indication to perform a first governor function for controlling the speed of the elevator car responsive to the elevator car moving at a speed above a first threshold speed. A second governor sheave is supported on the elevator car for movement with the elevator car and for rotational movement relative to the elevator car responsive to movement of the elevator car. A second governor tripping mechanism is supported on the second governor sheave. The second governor tripping mechanism provides an indication to perform a second governor function for controlling a speed of the elevator car responsive to the elevator car moving at a speed above a second threshold speed.
