Product Introduction
The SKL14 spring-clip rail fastening system is a high-performance rail elastic fastener device used in high-speed railways and heavy-load lines. Its core is the SKL14 spring-clip made of special alloy spring steel, which produces a long-lasting and stable buckling pressure through precisely designed elastic deformation.
The system consists of a spring-clip body, a composite insulating pad, a reinforced anchor bolt and a gauge adjustment component. It uses a double locking mechanism to ensure a reliable connection between the rail and the ballastless track or concrete sleeper, and can still maintain excellent fatigue resistance when bearing an axle load of more than 30 tons. Its innovative variable stiffness design enables the system to have both rigid constraints and elastic buffering functions, which can effectively control the longitudinal and lateral displacement of the rail, absorb the impact vibration generated by the high-speed operation of the train, and cooperate with the insulating components to achieve an insulation impedance of more than 1500V for the track circuit. The system is particularly suitable for high-speed passenger dedicated lines with a speed of more than 300 kilometers per hour and heavy-load lines with an annual total weight of more than 100 million tons. Its anti-loosening and anti-rust design and 100,000 cycle load test performance enable the track structure to maintain its geometric shape and position accuracy in an ambient temperature of -40℃ to +60℃, significantly improving line smoothness and operational safety.
