Abstract
A governor assembly is provided including a sheave rotatably mounted on a shaft and a ratchet disc mounted on the shaft. Rotation of the ratchet disc is restricted. An overspeed assembly includes a swing jaw mounted to the sheave. The swing jaw is movable between a normal position and a tripped position. The swing jaw is biased into the tripped position. When the swing jaw is in the tripped position, rotation of the sheave in a first direction is restricted. A tripping lever is pivotally mounted to the sheave and is configured to cooperate with the swing jaw. Rotation of the sheave in a second, opposite direction is configured to automatically move the swing jaw against its bias to the normal position.
