Railway SKL15

SKL rail clips are a type of elastic fastener widely used on German railways to secure rails and ensure train safety. SKL clips generate clamping pressure through bending and twisting, effectively connecting rails and sleepers, preventing longitudinal and lateral movement of the rail relative to the sleeper and absorbing the impact energy of passing vehicles, providing a shock-absorbing effect.
