  Einrichtung zum Nachspannen der Fahrleitung elektrischer Bahnen. 



   Wird beim Na'spannen von Kettenlinien-Fahrleitungen die Schrägstellung der Hängedrähte gemäss dem österreichischen Patente Nr.   714ó6   benutzt, so ist in den Mitten der Spannweiten eine Mindestlänge der Hängedrähte erforderlich, die die Höhenlage des Tragseils über dem Fahrdraht bestimmt. Gegenüber anderen Fahrleitungen, bei denen Tragseile und Fahrdraht in der Mitte der Spannweite nahezu in derselben Höhe liegen, ergibt sich infolgedessen der Nachteil, dass die für die Lagerung des Tragseils dienenden Ausleger oder Joche von entsprechend längeren Masten getragen werden müssen. 



     Erfindungsgemäss   wird die Verwendung längerer Maste dadurch vermieden, dass in den Mitten der Spannweiten an dem Tragseil nach aufwärts gerichtete Bügel angeordnet

  Device for re-tensioning the catenary of electric railways.



   If the inclined position of the suspension wires according to Austrian patent no. 714ó6 is used when tensioning catenary catenaries, a minimum length of suspension wires is required in the middle of the spans, which determines the height of the suspension cable above the contact wire. Compared to other overhead lines, in which the suspension ropes and contact wire are almost at the same height in the middle of the span, there is consequently the disadvantage that the booms or yokes used to store the suspension rope must be supported by correspondingly longer masts.



     According to the invention, the use of longer masts is avoided in that upwardly directed brackets are arranged in the centers of the spans on the supporting cable
