Where are SKL Clips used?
Dec 03, 2025| SKL Clips are elastic fasteners widely used in modern railway fastening systems. They are primarily used to reliably secure rails to sleepers or track slabs, while providing necessary elasticity and vibration damping. Due to their structural stability, strong clamping force, and excellent fatigue resistance, SKL Clips are widely used in various railway and rail transit scenarios.
1. Conventional Railways and Heavy-Haul Railways
SKL Clips are commonly used in conventional and heavy-haul railway lines. Under heavy load conditions, rails bear significant axle loads and repeated impacts. SKL Clips effectively prevent rail loosening and displacement through stable elastic clamping force, ensuring long-term stability of track gauge and alignment.
2. High-Speed Railways
High-speed railways have extremely high requirements for track geometry accuracy and operational stability. SKL Clips possess excellent elastic properties and fatigue life, capable of absorbing the dynamic loads generated by high-speed trains and reducing the impact of vibration on the track structure. Therefore, they are widely used in ballastless track or high-standard ballasted track systems.
3. Urban Rail Transit (Metro, Light Rail)
SKL Clips are widely used in metro and urban rail transit systems. Their flexible connection helps reduce the transmission of vibration to the track slab and surrounding buildings. When used in conjunction with vibration-damping components such as rubber pads, they effectively improve noise and vibration issues in urban environments.
4. Bridge and Tunnel Sections
In sections with high structural rigidity, such as bridges and tunnels, the track system is more susceptible to vibration and temperature changes. SKL Clips can compensate for the thermal expansion and contraction of the rails within a certain range while maintaining stable clamping force, making them ideal for bridge sections, tunnel sections, and special structural sections.
5. Various Concrete Sleeper and Track Slab Systems
SKL Clips are compatible with various concrete sleepers, track slabs, and fastener bases, offering strong adaptability, convenient installation and maintenance, and suitability for large-scale railway projects and long-term operational lines.
SKL Clips are mainly used in conventional railways, high-speed railways, heavy-haul railways, urban rail transit, and special sections such as bridges and tunnels. It secures the rails with a stable elastic clamping force and provides excellent vibration reduction and fatigue resistance, making it an indispensable component in modern railway fastening systems.
