Abstract (en)
[origin: EP1852383A1] A speed governor sheave rotatable about a sheave shaft and a friction pulley rotatable coaxially with the speed governor sheave are supported on a pedestal. The speed governor sheave is provided with a flyweight that is turned due to a centrifugal force resulting from rotation of the speed governor sheave. The speed governor sheave is turnably provided with a contact for rotating the friction pulley in the same direction as the speed governor sheave when the speed of a car reaches a predetermined overspeed by coming into contact with the friction pulley. The friction pulley is provided with an engagement member for operating a switch lever of a car stop switch when the speed of the car reaches the predetermined overspeed. The switch lever, which normally engages with the engagement member, is operated when the friction pulley is rotated.
