 hoch haltenden Zylinders mit Kolben eine Drosselvorrichtung eingeschaltet. Die Drosselung ist so eingestellt, dass die Sicherheitsbremskraft erst dann voll zur Wirkung kommt, wenn die bewegten Massen zum Stillstand gekommen sind oder wenn sie so weit verzögert worden sind, dass die zunehmende Bremskraft keine schädliche Wirkung (Seilrutseh) ausüben kann. 



   Für besondere Fälle kann es jedoch erwünscht sein, die Wirkung der Drosselvorriehtung zu schwächen oder ganz aufzuheben. Diese Möglichkeit wird nach der Erfindung dadurch geschaffen, dass die Wirkung der Drosselvorriehtung durch Bewegen des Sicherheitsbremshebels über seine Endlage hinaus geschwächt oder aufgehoben werden kann. 



   Die Zeichnung gibt ein Ausführungsbeispiel für die Erfindung. 1 ist der Hauptbremshebel, an dem in Punkt 2 der Fahrbremsmotor. 3, 4 angreift. An seinem langen Ende greift bei Punkt 5 die Stange 6 
 EMI2.1 
 
Durch das Auslösen der Sicherheitsbremse wird der Zylinder 9 von der   Druckleitung 16 abgeschlossen   und mit dem Auspuffrohr 19 verbunden. In dieses Rohr ist eine Drosselvorrichtung 119 eingeschaltet, die so eingestellt ist, dass das Gewicht 8 nur langsam absinken kann und erst dann zur Wirkung kommt,

    Safety device for moving masses.
 EMI1.1
 

 <Desc / Clms Page number 2>

 high holding cylinder with piston switched on a throttle device. The throttling is set in such a way that the safety braking force is only fully effective when the moving masses have come to a standstill or when they have been decelerated so far that the increasing braking force cannot have any harmful effect (rope slips).



   For special cases, however, it may be desirable to weaken or completely cancel the effect of the throttle device. This possibility is created according to the invention in that the effect of the throttle device can be weakened or canceled by moving the safety brake lever beyond its end position.



   The drawing gives an embodiment for the invention. 1 is the main brake lever, where in point 2 the traction brake motor. 3, 4 attacks. At its long end, the rod 6 grips at point 5
 EMI2.1
 
When the safety brake is triggered, the cylinder 9 is closed off from the pressure line 16 and connected to the exhaust pipe 19. A throttle device 119 is switched into this tube, which is set so that the weight 8 can only drop slowly and only then comes into effect,
