Description
Čeština: Napínák drátovodu k semaforu před železniční stanicí Davle ve směru od Libřice.
English: Davle, the Czech Republic.
Deutsch: Bahnhof Davle, Bezirk Prag-West, Strecke Čerčany–Vrané nad Vltavou, Drahtnachzughebel in einer Signalleitung. Die Drahtnachzughebel werden bei altösterreichischen mechanischen Stellwerken ohne Spannwerke insbesondere in die langen Leitungen zu den Einfahrsignalen bzw -vorsignalen eingebaut. Bei einem Drahtbruch zwischen Stellwerk und Drahtnachzughebel bewirken die Gewichte, dass der betroffene Strang am Signalantrieb zuverlässig soweit entspannt wird, dass der Signalantrieb auskuppelt, das Signal die Haltlage erreicht und in ihr festgehalten wird.
Die Leitungsstränge links kommen vom Stellwerk, die nach rechts führen zum Signal. Mit den unterschiedlichen Hebelverhältnissen wird der Stellweg der Leitung an den für den Signalantrieb erforderlichen angepasst. Die Spannschrauben in allen vier Leitungtssträngen sind zum Einregulieren der Signalleitung und fallweise für den Ausgleich von Längenänderungen bei großen Temperaturunterschieden erforderlich.
