Technical Parameters
Rail SKL Type Elastic Fastening Clips
| Parameter | Specification & Description |
|---|---|
| Product Name | SKL Type Railway Elastic Clip |
| Primary Function | To securely fasten the rail to the sleeper (concrete/steel) or track slab, maintaining gauge and providing longitudinal restraint. |
| Application | Mainlines, heavy-haul lines, tunnels, bridges, switches, and crossings. |
| Working Principle | The clip is pressed into a shoulder and elastically deforms. Its spring force (toe load) clamps the rail base against the baseplate, preventing movement. |
| Material | High-carbon spring steel (e.g., 60Si2MnA, 60CrMnA, SUP9/10 per JIS G4801). |
| Material Standard | ASTM A689, EN 13230, AREMA, GB/T 1222, or project-specific specs. |
Key Advantages
- High Elasticity & Fatigue Resistance: Provides a consistent, reliable clamping force for long-term safety.
- Excellent Longitudinal Restraint: Prevents rail creep under traffic.
- Maintains Track Gauge: Ensures geometric stability of the track.
- Simple Installation & Maintenance: Can be installed and removed with specialized tools.
- Good Electrical Insulation: When used with polymer insulators.
