Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Elastic Rail Clip specifically designed for heavy haul rail track fixing. This clip incorporates an advanced anti-loose locking mechanism that ensures secure fastening under extreme loads and dynamic conditions. With annual export values reaching US$5–10 million and a global market presence across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, our product is engineered to deliver exceptional reliability and long-term performance in demanding railway environments.
Our Elastic Rail Clip is manufactured from high-quality spring steel, heat-treated to achieve optimal elasticity and fatigue resistance. The unique anti-loose design effectively prevents clip displacement caused by train vibrations, thermal expansion, and heavy axle loads, reducing maintenance frequency and extending track life. Whether for new railway construction or track rehabilitation, this clip meets the rigorous standards of heavy haul operations.
Key Features & Technical Specifications
- Material Excellence: Made from premium spring steel (e.g., 60Si2MnA) with strict chemical composition control, ensuring consistent hardness and elasticity.
- Anti-Loose Locking Mechanism: Patented geometry that provides a tight, self-locking grip on the rail base, minimizing slippage even under repeated heavy loading.
- Fatigue Life: Tested to withstand over 5 million cycles without failure, suitable for high-frequency heavy haul traffic.
- Corrosion Resistance: Available with black oxide, epoxy coating, or hot-dip galvanizing to suit different environmental conditions.
- Easy Installation: Designed for quick installation using standard rail fastening tools, reducing labor costs and downtime.
- Compatibility: Fits standard rail profiles (e.g., UIC60, 60E1, 75kg/m) and can be customized per customer specifications.
- Vibration Damping: The elastic properties help absorb shock and reduce noise, contributing to smoother rail operation.

Frequently Asked Questions
Q1: What is the typical lifespan of your elastic rail clip under heavy haul conditions?
A: Our clips are designed to last at least 5 million cycles in fatigue testing, which corresponds to several years of heavy haul service depending on traffic density. Actual life may vary with maintenance and environmental factors.
Q2: Can the clip be used on curved tracks?
A: Yes, the elastic clip is suitable for both straight and curved tracks. The anti-loose mechanism ensures stable fastening even on curves with small radii.
Q3: What surface treatment options do you offer?
A: We offer black oxide, epoxy coating, and hot-dip galvanizing. The choice depends on the corrosion environment. For coastal or humid areas, hot-dip galvanized is recommended.
Q4: Do you provide samples for testing?
A: Yes, we can provide samples (usually 5–10 pieces) for quality evaluation. Please contact our sales team with your shipping details, and we will arrange a sample shipment.
Q5: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard elastic rail clips is typically 5000 pieces. For customized clips, the MOQ may be higher; please inquire for details.
Q6: How do you ensure the anti-loose performance of the clip?
A: The clip's geometry is designed to create a self-locking force that increases with vibration. We also perform dynamic testing to verify that the clip maintains clamping force after repeated loading.
Q7: Are your clips compatible with standard rail pads and baseplates?
A: Yes, our clips are designed to work with standard rail fastening systems. We can provide installation instructions and compatibility data upon request.
Q8: Can you customize the clip dimensions or material?
A: Absolutely. We have an experienced engineering team that can develop custom clips based on your rail profile, load requirements, and track conditions. Contact us with your specifications.
