DFH Installation & Renewal Machine of Catenary in Constant Force

The machine is a special vehicle for winding of catenary and carrying cable as well as catenary setting and stretching of electrified railway. The vehicle is able for both separate and simultaneous erection and recovering of catenary and carrying cable. During catenary setting and stretching process, the catenary and carrying cable are always maintained at a predetermined tension and both catenary and carrying cable are supported to their respective required positions. The vehicle is equipped with two independent tension mechanisms which use double friction wheel structure. It has the tightening guide pulley to prevent strain due to dislocation of catenary or carrying cable. The hydraulic lifting and slewing operation platform uses double acting cylinder to achieve lifting and 120° slewing to left and right and provides the operation space for six or seven operators at the same time on the platform.
