Rail Clip Types | Reliable Rail Clip Manufacturer from China

What Is a Rail Clip

The elastic rail clip serves as the core component of the rail fastening system. It delivers stable clamping force through precise elastic deformation to firmly secure the rail onto sleepers or base plates. When trains pass and create impact and vibration, the elastic rail clip bears vertical, lateral and longitudinal forces transferred from the rail. It undergoes combined bending and torsional deformation to maintain restraint upon the rail, and ensure stable track position. Therefore, the elastic rail clip is an indispensable component for the safe operation of railway tracks. As a specialist manufacturer of rail fasteners in China, we supply elastic rail clips in diverse profiles, which comply with a wide range of international standards. Below, we have listed our available elastic rail clip types for global markets and domestic markets. See the following sections for details.

Rail Clip Types

1. Elastic Rail Clip Types Available from Our Factory for Global Markets

a. 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 compatible with various types of railway sleepers and are one of the most widely‑used, highly cost‑effective elastic rail fasteners worldwide. We supply various E‑type rail clips, including E1609, E1809, E1813, E2001, E2007, E2009, E2055, E2056, E2063, as well as custom elastic rail clips manufactured to clients’ drawings and specifications. 

b. SKL Tension Clamp

Our SKL tension clamps are mainly used for railway concrete sleepers and concrete switch sleepers compared with E‑type rail clips. SKL tension clamps are kind of 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 find wide application in turnouts under complex stress conditions, high‑speed railways, heavy‑haul lines and metro lines. Anti‑corrosion treatments such as hot‑dip galvanizing and protective coatings can be provided according to customer requirements for our SKL elastic rail clips. We supply various E‑type rail clips, including SKL1, SKL3, SKL12, SKL14, SKL21, SKL30, and custom SKL rail clips manufactured to clients’ drawings and specifications. 

c. Fast Rail Clip

Fast 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 track‑gauge adjustment capability. These Fast rail clips are compatible with railway concrete sleepers as well as steel sleepers. They find wide application in high‑speed railways, metro lines and heavy‑haul lines, and are ideal for large‑scale mechanized track‑laying. And we can manufacture custom SKL rail clips manufactured to clients’ drawings and specifications.  

d. Nabla Clip

Nabla Clip manufactured by us is a V‑shaped elastic spring‑steel fastener. When bolts are tightened, its spring plate generates elastic clamping pressure to secure the rail foot. It enables dual adjustment of track gauge and rail height, delivers superior electrical insulation and offers high resistance to lateral forces. Our Nabla clip is especially suited for small‑radius curved tracks. It also finds wide application in concrete‑sleeper high‑speed railways, metro, tram, bridge and tunnel lines. It dampens vibration and noise, keeps consistent track gauge and requires low-maintenance operation. And we can manufacture custom nabla clips manufactured to clients’ drawings and specifications.  

e. Deenik Clip

Deenik clips manufactured by us feature an asymmetrical bending structure: one end applies clamping pressure to the rail foot, while the other locks into the slot of the pre-embedded iron chair. They are 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 running trains. They are mainly suitable for concrete sleepers and find wide application on railway lines across Europe (the Netherlands, Germany) and South America. And we can manufacture custom deenik clips manufactured to clients’ drawings and specifications.  

f. Russian Rail Clip

Russian rail clips are elastic rail clips mainly used for Russian railway lines. All our Russian rail clips are manufactured in full compliance with Russian GOST standards. They deliver outstanding durability and reliable performance. Its advantages include high reliability, guaranteed track‑gauge stability, simple structure, low material consumption, and easy installation. 

And its core advantage lies in excellent low‑temperature resistance and stable elasticity under extreme cold conditions. It is mainly suited for concrete sleepers applications. As a professional manufacturer and supplier of elastic rail clip for Russia railway fastener system, we can supply clients with high‑quality, reliable and durable railway elastic strip products to guarantee the stability and safety of railway systems. Feel free to contact us.

g. Crane Rail Clip 

Crane rail clips manufactured by us are a type of rail fastener within the rail fastening system. They fix rails to sleepers or sleeper pads, maintain rail spacing and prevent rail displacement. The core component‑our crane rail clamp plates are manufactured by forging or casting. These plates generate rigid clamping force upon bolt tightening to hold the rail firmly in position. Featuring good cost‑efficiency and consistent performance, they are extensively applied in crane rail fastening systems. They find wide use across multiple industries including container‑handling cranes, power‑plant coal unloaders, steel‑mill cranes, workshop overhead cranes and shipyard gantry cranes.
