Estimating the term…
A speed limiting device for lifts or the like comprising a cable wheel drivable by means of a speed limiter cable secured to the lift cabin, a cam disk fixably connected with the cable wheel and seated upon a common shaft or axle, and a support movable by the cam disk and the speed limiting device upon exceeding a predetermined lift travel speed, decelerating the speed limiter cable. There is provided a separate cable brake acting upon the limiter cable and an actuation mechanism which can be actuated with a tilting behavior upon activating the separate cable brake. The actuation mechanism comprises at least one mass body accelerated by the support proportional to the lift travel speed during rotation of the cam disk, the mass body upon exceeding a predetermined travel speed is movable relative to the support under the action of the inertia forces for releasing or triggering the actuation mechanism.
A speed limiting device for lifts or the like including a lift cabin, comprising a limiter cable attachable to the lift cabin, a cable wheel drivable by means of the limiter cable, a shaft, a cam disk fixedly connected with the cable wheel and seated together with said cable wheel upon said shaft, a support which is moved by said cam disk, a separate cable brake acting upon the limiter cable, actuation means which upon activating the separate cable brake is actuated with a tilting action, said actuation means possessing at least one mass body which is accelerated substantially proportionally to the lift travel speed by the support when the cam disk rotates, said mass body upon exceeding a predetermined travel speed being movable relative to the support under the action of the inertia forces for releasing the actuation means, a bearing plate, said support comprising a single-arm lever rotatably mounted in said bearing plate, said lever being branched at one end thereof to form an upper branched portion and a lower branched portion, each branched portion being provided with an inclined portion and a notch, a roller rotatably mounted at said lever, and spring means for pressing said roller against the periphery of the cam disk.
