1. We specialize in the manufacturing and supply of premium elastic rail clip products, essential for railway applications. Engineered from superior quality raw materials, these elastic rail clips are meticulously designed for exceptional tensile strength and unparalleled corrosion resistance. Furthermore, our offerings can be customized to meet the unique requirements of our clients, ensuring competitive pricing and tailored solutions.
Renowned within the railway industry, our elastic rail clips deliver outstanding clamping performance for rails, combined with effortless installation.
As proprietary technologies from leading manufacturers (Pandrol and Vossloh) have entered the market, SUYU has partnered with esteemed quality producers to provide an economical range of elastic rail clips tailored for various rail sections and applications, including the esteemed SKL tension clamp.
Through rigorous dimensional control and the utilization of high-quality spring steel, SUYU ensures that our elastic rail clips and other railway fastenings consistently meet stringent customer specifications.
Our expertise enables us to produce elastic rail clips suited for any toe load and axle load requirements, ensuring secure rail fixation on wooden, steel, or concrete sleepers. We offer an array of elastic rail clips with steel bar diameters ranging from 12mm to 20mm. Specifically, we manufacture diverse types of elastic rail clips with flat toes for broad gauge lines, featuring toe loads from 850kgf to 1100kgf, and we can accommodate any desired toe load and axle load for rail fixation on various sleeper types.
Technical Specifications of the Elastic Rail Clip| Diameter | Weight (Kg) | Toe Load |
| 12mm | 0.18 | 200-400 |
| 14mm | 0.30 | 400-600 |
| 16mm | 044 | 500-700 |
| 18mm | 0.60 | 800-1000 |
| 20mm | 0.78 | 1100-1400 |
Our elastic rail clips boast a fatigue life of up to 5 million cycles without failure when the spring steel deflection reaches 9.1mm.
Material: 60Si2MnA
Surface Finish: Plain, black painting, red painting
Minimum Order Quantity: 5000PCS
Packaging: Plastic bags and wooden pallets, or as per clients' requirements
2. We are the leading manufacturer and exporter of the SKL tension clamp, designed to ensure the electric insulation of the rail on its support. Our tension clamps facilitate the elastic maintenance of the rail in both vertical and transverse directions. The fixing and supporting device includes a support table for the rail, a projecting shoulder on each side, an interposed pad, an insulating clip, elastically yieldable strips, and fixing equipment that traverses the body's apertures of the elastic rail clip and the strip.
Our boltable elastic rail clip delivers robust permanent clip strength, ideal for rail construction with concrete sleepers. Available in diameters 13mm to 15mm, our range includes SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, SKL30, and more.
| Diameter | Type | Weight (Kg) |
| 13mm | SKL1 | 0.49 |
| 13mm | SKL3 | 0.53 |
| 13mm | SKL12 | 0.53 |
| 13mm | SKL14 | 0.505 |
