Rail skl Clip Fastening System
Railway SKL Clip is a high‑performance elastic fastener widely used in railway track systems, designed to firmly fix rails and base plates, absorb vibration and impact from trains, resist loosening under long‑term dynamic loads, and maintain stable track geometry for safe and reliable operation.

Installation & Maintenance Perspective:
- Provides strong and stable clamping force to restrict rail displacement effectively
- Maintains consistent elasticity under repeated high‑frequency train loads
- Reduces stress concentration to avoid fatigue cracking during long service
- Resists vertical, lateral and longitudinal forces in various working conditions
- Ensures reliable connection between rail and fastening system steadily
Maintenance & Operational Perspective
- Dedicated hydraulic tool ensures repeatable clamping force across track.
- Calibrated pressure eliminates human error in force application.
- Visual leg position confirms correct seating without gauges.
- Heat number traceability follows material from melt to finished clip.
- EN 13230-5 certification guarantees batch consistency.
