Fasteners E 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.

Description

Technical Parameters

↵Rail e clip Fastening System

A Railway E Clip is a resilient fastening device forged from durable alloy steel, characterized by its distinctive 'E' silhouette, which functions as a tension clamp to lock the rail base securely against the sleeper. It serves as the critical interface that transfers dynamic train loads into the track structure while maintaining precise rail gauge and preventing undesirable movement.

Compatible Rail Section	UIC 54, UIC 60, ASCE profiles	Universal application across rail types.

Installation & Maintenance Perspective

Installation & Maintenance Perspective:

Shoulder Compatibility: Precision-engineered to lock firmly into pre-cast iron or spring-loaded shoulders embedded in concrete sleepers.

Insulation Compatibility: Designed to work seamlessly with nylon or rubber insulators, preventing electrical current leakage for signal circuitry.

Gauge Retention: Works in pairs to maintain strict track geometry by preventing the rail from rotating or tilting under uneven loads.

Maintenance & Operational Perspective

Vertical Force Absorption: Compresses under the weight of passing trains to cushion the sleeper from impact, then returns to original shape to maintain grip.
Lateral Restraint: The outer legs of the "E" provide stiff resistance against side forces from trains negotiating curves.
Tension Maintenance: Unlike rigid clips, it maintains constant tension even as the rail expands or contracts with temperature changes.
