Keilführungselemente 12 und der Reibung zwischen den
Bremsbelägen 14 auf dem Führungsschenkel 2.1 werden die
Bremskeile 13 in die Bremseinrichtung 6 bewegt und die
Feder- und Justierpakete 10,11 gespannt, wobei die von der
Reibungskonstante zwischen den Bremsbelägen 14 und dem
Führungsschenkel 2.1 sowie von der Federkonstante abhängige
Bremskraft zur Stillsetzung der Aufzugskabine oder des
Gegengewichtes erzeugt wird.In an emergency, the governor rope 7 by the
