▪ High stiffness and high elasticity rail fastening system for the high speed of ballastic bed
▪ Extend useful life due to expansion of fatigue amplitude of coil spring clip
▪ Application section: No more than 350km/h
eco-clip - Increase the longitudinal friction factor increase the displacement range - Change the shape of the toe to get the areal contact with insulator and increase the whole length to increase displacement range to accommodate the elastic pad deflection |
|
Insulator - Stress decreased by areal contact with eco-clip - Extended life cycle |
|
Rail Pad: high elastic pad made of EPDM - Static stiffness: 60kN/mm+/-10% - Stiffness variation after repeated load test by EN Standard: +/-5% - Guarantees the long life cycle |
|
Shoulder - Increase torsional resistamce |
|
PC Sleeper - Designed more bigger and wider - Decrease the trackbed stress - Secure the safe vehicle travelling at high speed |
