Features
Elastic rail clips are pre-stressed spring steel fasteners that secure rails to sleepers while allowing controlled vertical movement. These critical components maintain track gauge and absorb dynamic loads in modern rail fastening systems.
Common Types of Elastic Rail Clips
| Type | Material | Tension Force | Application |
|---|---|---|---|
| Pandrol e-Clip | 60Si7CrV steel | 9-11 kN | Concrete sleepers |
| Vossloh SKL | 51CrV4 steel | 8-10 kN | Wood/concrete sleepers |
| Nabla SPR | 60Si7 spring steel | 10-12 kN | Heavy haul lines |
| DE Fastclip | SAE 5160 steel | 7-9 kN | Light rail systems |

Step-by-Step Installation
Clip Positioning
Align clip toes with shoulder grooves Ensure proper orientation (manufacturer marks visible)
Verify clip type matches rail profile
Application Process
Manual Installation:
Place applicator tool on clip
Apply steady pressure until "click" is heard
Verify both toes are fully engaged
Mechanical Installation:
Position hydraulic tool
Set pressure to 12-15 kN
Engage until auto-release triggers
Post-Installation Checks
Visual inspection of toe engagement
Measurement of clip height (compare to specs)
Verification of rail freedom (0.5-1mm vertical movement)
