Heavy Steel Fast Clips

Heavy Steel Fast 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 Fast Clip Fastening System

Railway Fasteners Carbon Fast Clip

The Fast Clip is an elastic rail fastener that locks into a cast shoulder using a simple lever action. Made from heat-treated spring steel, it applies constant downward force on the rail foot without bolts or threads. Its one-piece design allows rapid manual or mechanized installation. This system is widely used for metro, tram, and freight lines.

Elastic Rail Clamp

Installation & Maintenance Perspective:

  • Locking indicator shows clearly when clip reaches correct working position
  • No loose small parts means lower risk of foreign object debris on track
  • Retaining tang prevents clip ejection under severe lateral wheel impacts
  • Visible gap closing confirms proper clamping force without measurement tools
  • Remains captive in shoulder even if tension is accidentally released

 

Maintenance & Operational Perspective

  • Nestable shape allows compact stacking reducing warehouse space by 40 percent
  • No component mixing required unlike multi-part bolt and spring washer systems
  • Single part number simplifies procurement and inventory management completely
  • Lightweight design lowers shipping cost per kilometer of track installed
  • Indefinite shelf life with basic rust prevention coating applied
