Product Overview & Features of Railway SKL Clip
| Item | Description |
|---|---|
| Product Name | Railway SKL Type Elastic Clip / SKL Clip |
| Standard | DIN 45660-1, Region-specific railway standards (e.g., TSI, EN) |
| Application | Used for fastening rails to concrete sleepers (ties) or baseplates in ballasted and ballastless track systems. |
| Core Function | To provide a reliable, maintenance-free elastic connection that clamps the rail firmly, ensuring gauge stability and absorbing dynamic forces. |
| Material | High-quality Spring Steel (Typically 60Si2Mn, 60CrMo, or equivalent) |
| Common Rail Sections | 54 E1, 60 E1, UIC 60, and other heavy-haul and high-speed rail profiles. |
Detailed Technical Parameters of SKL Clip
| Parameter | Value / Description | Remarks |
|---|---|---|
| Toe Load (Clamping Force) | 20.5 - 22.5 kN | The force exerted by the clip toes on the rail foot. Critical for secure fastening. |
| Test Load (Permanent) | ≥ 30 kN | The load the clip must withstand without permanent deformation. |
| Deflection at Test Load | ~ 11.5 mm | The vertical displacement under the test load. |
| Electrical Resistance | < 5 Ω (Per fastening assembly) | Ensures the rail circuit is continuous for signaling. |
| Corrosion Protection | ≥ 500 hours Neutral Salt Spray Test | For phosphated clips. Coated clips offer higher resistance. |
| Fatigue Performance | Passes 5 million cycles at ±8 kN dynamic load | Demonstrates long-term durability under traffic. |
| Installation Torque | 150 - 200 N·m | Torque for the securing nut (if applicable to the assembly). |
| Tensioning Tool | Hydraulic Tensioner or Manual Torque Wrench | Specialized tools are required for correct installation. |
| Weight (per clip) | Approx. 2.5 - 3.0 kg | Varies slightly by manufacturer and specific design. |
| Operating Temperature | -40°C to +80°C | Suitable for most climatic conditions. |
