1. We are dedicated to the exceptional manufacturing and supply of elastic rail clip products, engineered specifically for the railway industry. Crafted from premium-grade raw materials, these elastic rail clips are meticulously designed to offer superior tensile strength and outstanding corrosion resistance. Furthermore, our products can be tailored to meet clients' specifications at competitive prices.
Renowned industry-wide, our elastic rail clips deliver unparalleled performance in rail clamping, paired with straightforward installation.
As patents from key manufacturers like Pandrol and Vossloh enter the public domain, SUYU has partnered with esteemed manufacturers to present an economical range of elastic rail clips suitable for various rail sections and applications, including the selected SKL tension clamp.
Our elastic rail clips, along with other rail fastenings, undergo stringent dimensional checks and are made from superior spring steel to ensure compliance with specified standards and exceed customer expectations.
We excel in producing elastic rail clips to meet any toe load or axle load requirements, suitable for securing rails on wooden, steel, or concrete sleepers. Our elastic rail clips come in a variety of sizes, with steel bar diameters ranging from 12mm to 20mm. We offer diverse elastic rail clips designed with flat toes for broad gauge lines, featuring toe loads from 850kgf to 1100kgf, and can accommodate 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 |
Our elastic rail clips boast a fatigue life of up to 5 million cycles without breaking when the spring steel deflection is at 9.1mm.
Material: 60Si2MnA
Surface: Available in Plain, Black Painting, and Red Painting
MOQ: 5000PCS
Packing: Plastic bags and wooden pallets, customizable according to client requirements
2. We proudly lead as the manufacturer and exporter of the SKL tension clamp, ensuring the rail's electrical insulation on its support. These tension clamps are crucial for maintaining the rail's elasticity both vertically and transversely. Our system includes an effective rail support device, featuring a supportive table, projecting shoulders, insulation pad, and a robust insulating clip to ensure optimal rail support and performance.
Our boltable elastic rail clips offer high permanent strength, particularly suited for rail constructions with concrete sleepers. Available in diameters ranging from 13mm to 15mm, and covering types such as SKL1, SKL2, SKL3, SKL12, SKL14, SKL21, SKL30, etc.
| Diameter | Type | Weight (Kg) |
| 13mm | SKL1 | 0.49 |
| 13mm | SKL3 | 0.53 |
| 13mm | SKL12 | 0.53 |
| 13mm | SKL14 | 0.505 |
