  "textContent": "The invention relates to a method and a device for replacing a contact wire that is fastened by hangers to a support cable on an overhead line of a track, wherein continuous operation is achieved by simultaneously winding up an old contact wire and pulling a new contact wire with already final rope tension. In addition to direction-independent and uninterrupted processing of multiple contact wire runs with minimal manual effort on the part of assembly personnel, the necessary work passes and work levels are intended to be reduced in particular. According to the invention, continuous operation is realized in which the detachment of the old contact wire from the hanger and the clamping of the new contact wire in the hanger are performed in immediate succession in time in a single work step and in a single work level. According to the invention, this is also achieved by a device that has at least one unit for guiding and receiving the contact wire to be removed and at least one unit for guiding and receiving the contact wire to be installed, which is arranged axially symmetrically to the guiding and receiving unit of the contact wire to be removed in the working direction, which unit for guiding and receiving the contact wire to be installed leads the guiding and receiving unit of the contact wire to be removed in the working direction.",
