Rail fastening system is used to link steel rail with the sleeper parts (or other types of rail parts), it also known as the intermediate coupling parts. Its role is to make the steel rail fixed on the rail sleeper, at the same time maintain track spacing and prevent steel rail lateral movement relative to the rail sleeper.
Railway fastening system usually includes rail clip, screw spike, rail pad, tie plate, rail shoulder,stainless steel fasteners and so on. Rail fastener should be able to effectively maintain long-term and be reliable connection between steel rail and sleeper, and can give full play to the cushioning performance under dynamic effect, delay the orbit residual deformation accumulation.
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.
