Rail fastening system is a set of fasteners that used to connect steel rail and railway sleepers. Generally, the railway fastening system is required to have reliable connection, simple structure and features of elasticity, shock absorption and insulation. SKL rail fastening system is one kind of hot rail fastening system among the railway materials market.
As for the components of SKL railway fastening system, including SKL rail clips, rail pad, screw spike, tie plate, washer, plastic dowel, track bolt and nuts, etc. common sizes of SKL rail fastening system include SKL 12, SKL 14 and SKL 3 rail fastening 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:
