Abstract
The present invention provides a remote trigger device, a speed limiter assembly having the same and an elevator. The remote trigger device for the speed limiter assembly comprises: an actuator; and a rotating component, the rotating component being capable of rotating around a rotating axis in a rotating plane, the rotating component being actuated by the actuator to rotate from an idle position to a working position. During rotation of the speed limiter assembly, at the idle position, the rotating component is kept separated from an over-speed locking mechanism of the speed limiter assembly, and at the working position, the rotating component toggles a trigger member of the over-speed locking mechanism of the speed limiter assembly to trigger the speed limiter assembly. The structure of the remote trigger device according to the present invention is compact and simple.
