Claim 0:
1. A governor assembly comprising:
a bracket;
a rotatable rope sheave mounted on the bracket; and
a centrifugal mechanism associated with the rope sheave;
wherein, the centrifugal mechanism comprises:
a plurality of centrifugal members pivotally connected to the rope sheave, the plurality of centrifugal members being capable of unfolding under an inertial force associated with the speed of the rope sheave; and
a retaining mechanism by which the plurality of centrifugal members are retained in a contraction position;
wherein, the retaining mechanism is configured to retain the plurality of centrifugal members in the contraction position when the speed of the rope sheave increases to a first threshold with an acceleration smaller than a first acceleration.
