Rail Clip Types | Reliable Rail Clip Manufacturer from China

What Is a Rail Clip

The rail clip is the core component of the railway rail‑fastening system. It produces a stable clamping force via precise elastic deformation, firmly holding the rail in place on sleepers or base plates. When trains pass and generate impact and vibration, the elastic rail clip is subjected to vertical, lateral and longitudinal forces transmitted from the rail. Meanwhile, the elastic rail clip undergoes combined bending and torsional deformation, to sustain its restraint on the rail, and ensure stable track position. 

Therefore, the elastic rail clip is an indispensable component for the safe operation of railway tracks. We are a specialist manufacturer of railway fasteners, supplying elastic rail clips in diverse profiles and conforming to multiple international standards. Please refer to the following content for details. Below, we have listed our popular elastic rail clip types for domestic and international railway applications.

Rail Clip Types

Rail Clip Types Available for Global Markets

1. E-Type Rail Clip

Our E‑type rail clips are made of high‑quality spring steel, providing stable, long‑lasting clamping force. Their unique spring structure firmly secures the rail, allows minor controlled displacement, effectively absorbs operational vibration and impact, maintains stable track geometry, and prolongs rail service life. And our E‑type rail clips have the features of simple structure, low manufacturing cost, high fracture resistance, excellent vibration‑damping performance, reliable gauge stability and low maintenance cost. 

They also withstand complex working conditions including extreme temperature variations, heavy loads, moisture and corrosion, delivering consistent and reliable performance. They are also compatible with various types of sleepers and are one of the most widely‑used, highly cost‑effective elastic railway fasteners worldwide. We manufacture various E‑type rail clips, including E1609, E1809, E1813, E2001, E2007, E2009, E2055, E2056, E2063.

2. SKL Tension Clamp

Compared with E‑type rail clips, our SKL tension clamps are mainly used for concrete sleepers and concrete switch sleepers. SKL tension clamps are Ω‑ring‑shaped elastic fasteners. They exert clamping force on the rail foot via spring tension, damp train‑induced vibration and shock, and accommodate minor rail displacement. In combination with plastic dowels, they achieve electrical isolation, sustain a consistent track gauge, and resist lateral rail forces and overturning moments. 

They are widely used for turnouts under complex stress conditions, high‑speed railways, heavy‑haul lines and metro lines. Anti‑corrosion treatments including hot‑dip galvanizing or protective coatings are available as per customer requirements. Our manufactured SKL‑type rail clips include models: SKL1, SKL3, SKL12, SKL14, SKL21, SKL30.

3. Fastclip Rail Clip

Fastclip rail clips that we manufactured require no bolt‑tightening, and they are snapped directly into place with dedicated tools. They feature rapid assembly and disassembly, high installation efficiency, and enable track‑gauge adjustment. These fast clips are compatible with concrete sleepers as well as steel sleepers. They are widely used on high‑speed railway, metro and heavy‑haul lines and ideal for large‑scale mechanized track‑laying.

4. Nabla Clip

Our manufactured Nabla Clip is a V‑shaped elastic spring‑steel fastener. Once the bolts are tightened, its spring plate produces elastic clamping pressure to hold the rail foot. It enables dual adjustment of track gauge and rail height, delivers superior electrical insulation and provides high resistance to lateral forces. It is especially suited for small‑radius curved tracks. And it finds broad application in concrete‑sleeper high‑speed rail, metro, tram and bridge‑tunnel lines. It dampens vibration and noise, maintains consistent track gauge and requires low maintenance.

5. Deenik Rail Clip

Our manufactured Deenik rail clip has an asymmetrical bending structure: one end applies clamping pressure to the rail foot, and the other locks into the slot of the pre‑embedded iron chair. It is typically assembled with cast‑iron shoulders and ribbed base plates. It features uniform stress distribution, excellent elasticity, long anti‑fatigue service life as well as easy installation and maintenance. It delivers outstanding gauge‑holding performance under high‑temperature conditions and effectively absorbs vibration and impact generated by trains. It is mainly suited for concrete sleepers and widely used on railway lines in Europe (the Netherlands, Germany) and South America.

6. Russian Rail Clip

Our Russian type rail clip is a w‑shaped elastic rail clip that manufactured per Russian GOST standard. Its core advantage lies in excellent low‑temperature resistance and stable elasticity under extreme cold conditions. And it features easy installation and maintenance. It is mainly suited for concrete sleepers applications, and is widely used on 1520 mm broad‑gauge railway lines in Russia, Central Asia and other regions.

7. Crane Rail Clip 

The crane rail clamp plate is manufactured by forging or casting. It generates rigid clamping force through bolt tightening to hold the rail firmly in place. It features good cost-efficiency and consistent performance, and is extensively used for crane rail system applications.
