Customized SKL Clips

Customized SKL Clips

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 SKL clip Fastening System

SKL Clip For Railway Fastener

Railway SKL Clips are high-performance elastic fasteners manufactured from spring steel with a distinctive omega-shaped configuration, designed to provide consistent toe load through screw-down fixation systems. These clips function as the tensioning component within complete rail fastening assemblies, working in conjunction with angled guide plates and rail pads to maintain track geometry while absorbing dynamic forces from passing trains.

Technical Specifications:

Clip Type Diameter Toe Load Application Speed
SKL 12 13 mm 9 kN Up to 200 km/h
SKL 14 14 mm 11 kN Up to 250 km/h
SKL 15 15 mm 13 kN Up to 300 km/h
SKL 24 16 mm 15 kN Heavy haul
Material 38Si7/51CrV4 Heat treated Anti-corrosion coated
Standard UIC 864 EN 13146 AREMA Chapter 30
Elastic Rail Clamp

Installation & Maintenance Perspective:

  • Applied using manual or mechanical screw-drive tools
  • Deflection during installation indicates correct clamping force
  • Visual toe gap inspection confirms proper placement
  • Removable without damaging adjacent track components
  • Pre-set on sleepers for accelerated track laying

 

 

Maintenance & Operational Perspective

  • Linear load-deflection relationship within working range
  • Central loop distributes stress evenly across clip body
  • Maintains specified toe load after millions of load cycles
  • Accommodates rail lift-off up to 3mm without permanent set
  • Provides elastic restraint for both vertical and lateral forces
