1.We are proud to specialize in the manufacturing and supply of superior elastic rail clip products, essential to the railway industry. Crafted from top-notch raw materials, these clips are engineered with precision, boasting exceptional tensile strength and outstanding corrosion resistance. Our offerings are highly customizable to meet the specific requirements of our clients, all at competitive prices.
Widely recognized across the railway sector, our elastic rail clips deliver exceptional rail clamping performance, combined with effortless installation.
As the once-patented technologies from leading manufacturers like Pandrol and Vossloh have entered the public domain, SUYU has partnered with esteemed quality producers to deliver a cost-effective array of elastic rail clips suitable for diverse rail sections and applications, including selected SKL tension clamps.
Through rigorous dimensional control and the use of premium spring steel, SUYU ensures that our elastic rail clips and other railway fastenings meet stringent specifications, tailored to fulfill customer expectations.
We excel in producing elastic rail clips designed to meet a variety of toe load and axle load requirements for securing rails on wooden, steel, or concrete sleepers. Our range includes clips with steel bar diameters from 12mm to 20mm. We manufacture various types of elastic rail clips with flat toes for broad gauge lines, supporting toe loads from 850kgf to 1100kgf, and are fully capable of meeting any specific toe load and axle load needs.
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 |
With a spring steel deflection of 9.1mm, our elastic rail clips boast an impressive fatigue life, enduring up to 5 million cycles without breaking.
Material: 60Si2MnA
Surface: Available in plain, black painting, and red painting finishes.
MOQ: 5000PCS
Packing: Delivered in plastic bags and wooden pallets, or customized according to client specifications.
2.We are the leading manufacturer and exporter of the SKL tension clamp, designed to ensure electric insulation of the rail on its support. These clamps are primarily used for maintaining the rail elastically on its support in both vertical and transverse directions. Our design includes a support defining table for the rail, a projecting shoulder on each side, an interposed pad, an insulating clip with a cooperative body and nose portion, an elastically yieldable strip, and comprehensive fixing equipment.
Our elastic rail clip, known for its high permanent clip strength, is boltable and ideal for rail construction with concrete sleepers. It is available in diameters ranging from 13mm to 15mm and includes models such as SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, and SKL30.
| Diameter | Type | Weight (Kg) |
| 13mm | SKL1 | 0.49 |
| 13mm | SKL3 | 0.53 |
| 13mm | SKL12 | 0.53 |
| 13mm | SKL14 | 0.505 |
Fatigue Property: Endures no less than 5 million cycles.
Loading Property: Displacement ranges between 9-12mm under pressure of 8-12KN.
Material: 60Si2CrA
Surface: Available in plain, black painting, and red painting finishes.
MOQ: 5000PCS
Packing: Delivered in plastic bags and wooden pallets, or customized according to client specifications.
