Abstract

A device for automatically maintaining a predetermined tensioning force in a contact wire or supporting cable (1, 2) of overhead lines of electrical railways with a tensioned elastic intermediate element (4), in particular in the form of a compressed helical spring arrangement, requires very little space because on the one hand it has a mechanical series connection of the elastic intermediate element (4) as well as a tension-increasing drive (5), and on the other hand, a control device (8) with the elastic intermediate element (4) constructed in the form of a device for measuring the tensioning force, as an input element and with the tension-increasing drive (5) as adjustment drive.
