ABSTRACT:
A machine for installing a catenary cable of an electrical catenary of a track includes a machine frame, supported for mobility on the track by undercarriages, and a storage drum containing the rolled-up catenary cable which is pulled off the storage drum during installation with a pull-off force, the storage drum being mounted on an auxiliary frame. A vertically adjustable deflection roller is provided for guiding the catenary cable during installation.A friction winch serves for creating a pull-off resistance counteracting the pull-off force when the catenary cable is pulled off the storage drum during installation, thus producing an installation tension. The friction winch is arranged between the storage drum and the deflection roller and is mounted on a winch frame which is connected to the auxiliary frame. A force sensor for measuring the installation tension is positioned between the winch frame and the auxiliary frame in order to keep the desired installation tension stable.
