An elevator having a car and a suspension member or respectively hoisting member for carrying an operating weight. Furthermore, a power transmission is intended for moving the suspension member and the hoisting member over at least one moving surface of the power transmission. The power transmission and the suspension member or respectively hoisting member are rope-shaped and/or belt-shaped. Also, the power transmission and the suspension member or respectively hoisting member are physically separated from each other. The power transmission and the suspension member or respectively hoisting member are stretched against at least one supporting body.

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.
