Abstract (de)

Die Erfindung betrifft einen Aufzug zum Transport von Lasten und/oder Personen mit einem in einem Aufzugschacht bewegbaren Fahrkorb, mit dem ein Antrieb gekoppelt ist, und mit mindestens einem dem Fahrkorb und/oder einem dem Fahrkorb zugeordneten Gegengewicht zugeordneten Puffer, sowie mit einem Notendschalter zum Abschalten des Antriebs. Um den Aufzug derart weiterzubilden, daß die Montage des Notendschalters vereinfacht und die Tiefe einer Schachtgrube und/oder eines Schachtkopfes verringert werden können, wird erfindungsgemäß vorgeschlagen, daß der Notendschalter durch den Puffer oder eine dem Puffer zugeordnete Pufferauftrefffläche betätigbar ist. <IMAGE>
