DDF Installation & Maintenance Machine of Catenary Without Propulsion Power

DDF is a non-powered car, which requires coupling and marshalling with the CATENARY installation car to form an installation/setting and stretching working car during work. The setting and stretching tension is controlled by hydraulic system with accumulator, so that the setting and stretching tension can be properly maintained. The machine is applicable to installation, routine maintenance and emergency rescue of CATENARY wire and carrying cable for standard track gauge metro line.
