Clip Type I rail fastening system comprises of nut, flat washer, type I(type A, type B) clip, gauge guide, pad seat, screw spike and bottom plate.
Clip type I rail fastening system Is widely used for standard gauge straight line and the line that radius of curve is less than 300m, it connects 50kg/m, 60kg/m rail with concrete sleeper.
1）、Clamping force per rail seat ≥18 kN
2）、Longitudinal resistance per rail seat in no less than 9kN
3）、Fastener system should be in good condition after bearing 3 million times loading circulation, the gauge expansion should be less than 6mm.
4）、Adjustment data for both sides of single strand of rail: -8~+6 mm, adjustment data for gauge: -16~+12mm
Adjustment data for rail high-low position： 10mm.
