SKL Clips Railroad Fastening System

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

The Railway SKL Clip is a torsion-resistant, loop-shaped spring element precision-manufactured from oval-section alloy steel, serving as the active fastening component in modern concrete sleeper systems. Unlike simple bar clips, the SKL features a distinct central arch that stores mechanical energy when deflected by a tensioning screw, transforming rotational torque into a consistent vertical and lateral clamping force on the rail base.

Installation & Maintenance Perspective:

Oval Section Engineering: The clip is forged from oval wire rather than round stock, providing directional stiffness that optimizes spring performance in the critical clamping plane.

Torsional Resilience: The looped design absorbs torsional stresses from passing trains, preventing force concentration that could lead to material fatigue or cracking.

Multi-Axis Clamping: Simultaneously applies vertical hold-down force and lateral restraint, eliminating the need for separate gauge-retention components.

Maintenance & Operational Perspective

Visual Tension Indicators: Experienced track workers can assess clip tension visually by observing the deflection gap under the central loop, enabling rapid inspection without tools.
Selective Replacement: Damaged or fatigued clips can be swapped individually without removing adjacent clips or disturbing rail alignment, minimizing track occupancy time.
Torque Retention: Engineered to maintain consistent clamping force over millions of cycles, reducing the frequency of re-tensioning maintenance intervals.
