Anping County Boli Hardware Wiremesh Products Factory, established in 1998, brings over two decades of expertise in manufacturing high-quality rail fastening components. Our Elastic Rail Clip Fastening for Subway/Tramway Track is engineered with a specialized vibration damping design, specifically tailored for 1435mm gauge tracks. This product effectively reduces noise and vibration transmission, enhancing passenger comfort and prolonging track maintenance cycles. As a reliable manufacturer with annual export values ranging from US$5 million to US$10 million, we ensure consistent quality and competitive pricing for global clients.
Our elastic rail clip fastening system is designed to meet the demanding requirements of urban rail transit, including subways and tramways. The key features include:
- Superior Elasticity: The clip provides consistent clamping force, effectively absorbing dynamic loads and reducing rail wear.
- Vibration Damping: Integrated rubber pad or polymer insert minimizes vibration transmission to the track bed and surrounding structures.
- Corrosion Resistance: Spring steel with optional surface treatments (black oxide, phosphating, or hot-dip galvanizing) ensures long service life in various environments.
- Easy Installation: Pre-assembled design reduces installation time and labor costs. No special tools required.
- Maintenance-Friendly: The clip design allows for quick replacement without disturbing adjacent components.
- Compatibility: Suitable for 50kg/m, 60kg/m, and other standard rail profiles, with customizable dimensions for specific projects.
The following table summarizes key technical specifications of our standard elastic rail clip fastening system:
| Parameter | Value |
|---|---|
| Material | Spring Steel 60Si2Mn (or equivalent) |
| Tensile Strength | ≥ 1200 MPa |
| Hardness (HRC) | 38–45 |
| Clamping Force | 8–12 kN (adjustable) |
| Fatigue Life | ≥ 3 million cycles |
| Operating Temperature | -40°C to +80°C |
| Gauge | 1435mm (standard) |
| Weight per Clip | ~0.8 kg |
The vibration damping design is a standout feature of our product. By incorporating a high-damping elastomer layer between the clip and rail seat, the system reduces noise by up to 5-8 dB compared to conventional rigid fastenings. This is particularly beneficial for urban transit lines passing through residential areas or sensitive structures. Additionally, the elastic nature of the clip minimizes the risk of rail corrugation and extends the service life of both rail and fastening components.
Our factory, located in Hengshui, Hebei, China, operates with modern production lines and strict quality control. We have supplied rail fastening components to projects across North America, South America, Europe, Southeast Asia, Africa, and Oceania. With an annual export value of US$5-10 million, we have established long-term partnerships with rail operators, contractors, and distributors worldwide. Our flexible shipping options include ports of Tianjin, Qingdao, Shanghai, Foshan, and others, ensuring timely delivery.
We are confident that our Elastic Rail Clip Fastening System meets the highest standards of performance and reliability. Contact us today for samples, technical drawings, or a customized quotation. Let us support your next subway or tramway project with proven, durable fastening solutions.
Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of your elastic rail clip?
A: Under normal operating conditions, the clip can last over 10 years, depending on traffic load and environmental factors. Our fatigue testing shows a minimum of 3 million cycles without failure. -
Q: Can the clip be used on existing 1435mm gauge tracks without modification?
A: Yes, our clip is designed as a direct replacement for standard fastening systems. It is compatible with common rail profiles and sleeper designs. However, we recommend confirming the specific rail seat dimensions with our technical team. -
Q: Do you provide custom dimensions or special materials?
A: Absolutely. We can customize the clip geometry, spring stiffness, and surface treatment to meet your project requirements. Please provide your technical specifications for a tailored solution. -
Q: How does the vibration damping feature work?
A: The clip assembly includes a resilient pad (e.g., rubber or polyurethane) that isolates the rail from the baseplate. This absorbs dynamic forces, reducing vibration transmission and noise generation. -
Q: What surface treatments are available for corrosion protection?
A: We offer black oxide, phosphating, and hot-dip galvanizing. For severe environments, galvanizing is recommended. All treatments comply with international standards. -
Q: Is there a minimum order quantity (MOQ)?
A: Our MOQ is typically 1,000 pieces for standard designs. For custom orders, the MOQ may vary. We also offer sample orders for evaluation. -
Q: What is the lead time for production?
A: For standard products, lead time is 15–20 working days after order confirmation. Custom orders may require 25–30 working days, depending on complexity. -
Q: Do you have any experience supplying for subway projects?
A: Yes, we have supplied rail fastening components to multiple subway and light rail projects in China and abroad. Our products are used in systems that require high reliability and low maintenance.
