| Parameter | Description & Details |
|---|---|
| Product Name | SKL Railway Clip / SKL Tension Clip |
| Common Names | SKL Clip, SKL Spring Clip, "B" Clip (due to its characteristic shape) |
| Primary Function | To clamp the rail foot to the sleeper/baseplate with high initial tension and rigidity, providing strong longitudinal restraint and high toe load. |
| Applicable Rail Sections | Primarily designed for UIC 54E1 and UIC 60E1 rails. Also used for other sections like 49E1, 50E2. |
| Standard Material | High-Carbon, Cold-Drawn Spring Steel Wire (e.g., Grade 60CrA according to TL 91871). |
Railway SKL Clip - Application
| Aspect | Details |
|---|---|
| Application System | The core component of the SKL Fastening System. Used on concrete sleepers with a dedicated cast-in shoulder. |
| Installation Method | Hammer Blow. It is pressed into its designated housing using a special hammer-driven guiding mandrel or hydraulic tool. The impact seats the clip firmly. |
| Installation Tool | Specialized SKL Clip Tongs for manual handling and a Guiding Mandrel struck with a hammer. Hydraulic tools are used for large-scale installation. |
| Advantages | - High Clamping Force: Provides exceptional longitudinal and lateral rail restraint. - Rigidity: Offers less dynamic flex than E-clips, suitable for high-stability areas. - No Heat Treatment: The cold-forming process eliminates potential heat treatment defects. - System Integrity: Designed as a complete, proven system with matched components. |
