SKL 12 Railway Fasteners System
As a typical type of SKL rail fastening system, SKL-12 rail fastening system is normally used in the ballast less track, which belongs to the separate rail fastening system of sleeper track plate without concrete retaining shoulder. Its main structural features as follows:
- Separate screw holes are arranged at both ends of ribbed plates and connected with railway sleeper/track plate by fork bolts.
- The ribbed plate is provided with t-bolt insert seat and retaining shoulder, and the elastic clip is fixed by tightening the nut of t-bolt.
- The horizontal and lateral adjustment is accomplished by using different sizes of eccentric heart taper pin.
- High and low adjustment of rail can be realized by inserting high and low setting plate.
