ABSTRACT:
During the installation of a catenary cable of a catenary of a track, the catenary cable is pulled from a storage drum, on which it is wound, and guided over winch wheels of a friction winch while being held under tension. From there, the catenary cable is passed onto a mounting roller with a pull-off resistance producing an installation tension. The pull-off resistance is created by the friction winch and counteracts a pull-off force of the catenary cable. Between the winch wheels of the friction winch, the cable tension is gradually increased up to the pull-off resistance.
