1. Product Introduction We are leading the way in the production and supply of elastic rail clip products, which play a critical role in railway operations. Manufactured using top-tier raw materials, these clips boast exceptional tensile strength and a high degree of corrosion resistance. Tailored to meet the specific needs and budget of our clients, our products set the benchmark for innovation and performance.
Globally recognized in the railway sector, the elastic rail clip is renowned for its superior clamping force and simple installation, ensuring optimal rail stability and safety.
Benefiting from the expiration of patents by both Pandrol and Vossloh, SUYU collaborates with esteemed manufacturers to deliver an economical selection of elastic rail clips, designed to accommodate various rail sections and applications, along with select SKL tension clamps.
Stringent dimensional controls, coupled with premium-grade spring steel, ensure that SUYU's elastic rail clips and complementary railway fastenings meet rigorous standards, tailored to fulfill customer specifications.
Our expertise extends to crafting elastic rail clips for any toe load and axle load requirement, suitable for timber, steel, or concrete sleepers. Offering a range of sizes from 12mm to 20mm in steel bar diameter, we manufacture diverse types with flat toes for broad gauge lines, delivering toe loads from 850kgf to 1100kgf. We are also adept at accommodating any load demands for various sleeper materials.
Technical Specifications of the Elastic Rail Clip: Engineering Excellence in Every Detail| 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 |
This clip achieves a remarkable fatigue life of up to 5 million cycles without failure when deflected by 9.1mm, thanks to its robust spring steel construction.
