  • Patent number: 11542122
    Abstract: A method of remotely tripping an overspeed assembly of a governor assembly includes generating a signal to indicate remote trip, applying power to an actuator, contacting a tripping lever with a movable member operably coupled to the actuator to rotate the tripping lever out of contact with an adjacent swing jaw, and biasing the swing jaw into contact with a ratchet disc capable of limited rotation in response to the tripping lever.
    Type: Grant

  • Patent number: 11155440
    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.

  • Patent number: 11040854
    Abstract: A method of operating an elevator or escalator system is provided. The method includes alerting a mechanic of a shutdown of a vehicle of the elevator or escalator system and providing data indicative of an occupancy condition of the vehicle to the mechanic so that the mechanic can execute, in any order, a verification of a no-occupancy condition, a switch of a mode of operation of the elevator or escalator system to a recovery mode and an inspection for faults. The method further includes initiating an overspeed (OS) switch reset routine in an event the mechanic confirms that an actuation of the OS switch is an exclusive cause of the shutdown and remotely triggers the OS switch reset routine accordingly.
