Good Hardness E Clip

Good Hardness E Clip

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Rail E Clip Fastening System

E Clips For Railway Fastening System

Railway E Clips are elastic fastening components manufactured from spring steel with a distinctive E-shaped geometry, designed to secure rails to sleepers through interference fit. These clips generate consistent clamping force by elastic deformation during installation, maintaining rail position while accommodating vertical deflection and lateral movement from passing trains without permanent set.

Technical Specifications:

Fatigue Life 3M cycles 5M cycles 7M cycles
Material Grade 60Si2Mn 38Si7 51CrV4
Standard Compliance UIC 864 AREMA EN 13481
Elastic Rail Clamp

Installation & Maintenance Perspective:

  • Three-pronged design distributes stress evenly across clip body
  • Outer legs provide primary retention against sleeper shoulders
  • Center leg applies downward force on rail foot
  • Optimized bend radii eliminate stress concentration points
  • Low-profile shape minimizes ballast interference

 

 

Maintenance & Operational Perspective

  • Linear deflection range 8-15mm within working limits
  • Energy absorption through elastic hysteresis
  • Vibration damping reduces track component fatigue
  • Self-adjusting to rail lift-off up to 3mm
  • Zero plastic deformation within design envelope
