Introduction
1. Type II rail fastening systems (also called Spring clip II fastenings) are suitable for connecting 60kg/m steel rails and prestressed concrete sleepers, prestressed wide concrete sleepers, and monolithic track beds on straight lines of standard gauge railways and lines with a radius of R≥300m;
2. When the fastener is assembled, the torque of the nut is controlled at 100~140N.m;
3. Adjust the top height of the rail by inserting a height-adjusting pad, and the maximum height-adjustment amount is 10mm;
4. Adopt the combination of different models of gauge baffle and baffle seat to adjust the gauge, the adjustment amount is -12~+8mm.
