As a professional manufacturer with over 25 years of experience in railway fastening systems, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Heavy Haul Railroad Rail Fastening System specifically designed for 100 kg/m rail and 70 kg/m concrete sleeper. This system incorporates an advanced anti-loosening design that ensures long-term stability under extreme dynamic loads. Our products are exported to more than 15 countries including North America, South America, Europe, and Southeast Asia, with annual export value exceeding US$5 million. We understand the critical demands of heavy haul railways and deliver solutions that prioritize safety, durability, and cost-efficiency.
Key Features & Technical Specifications
- Anti-Loosening Mechanism – Specially engineered clip and locking system prevents nut loosening caused by vibration and impact, reducing maintenance frequency.
- High Clamping Force – Provides consistent and reliable pressure on the rail foot, ensuring gauge stability even under heavy axle loads (up to 40 tons).
- Durable Material – Made from high-quality spring steel (60Si2Mn or equivalent) with optional surface treatments (black oxide, zinc plating, or Dacromet) for corrosion resistance.
- Compatible with 100 kg/m Rail – Precision-machined components fit UIC60/100RE rail profiles perfectly.
- Concrete Sleeper Ready – Designed for 70 kg/m concrete sleepers with pre-installed cast-in shoulders or separate shoulder plates.
- Easy Installation – Can be assembled using standard hydraulic or manual tools; no special skills required.
- Customizable Options – Available in different clip types (e.g., e-clip, fast clip), bolt sizes, and surface finishes to meet specific project requirements.

Frequently Asked Questions (FAQ)
-
Q: Is this fastening system suitable for curves and turnouts?
A: Yes, our system can be used on straight track, curves, and turnouts. For curves with radius less than 300m, additional gauge tie plates may be recommended. Please consult our technical team for specific applications. -
Q: How does the anti-loosening design work?
A: The system uses a combination of a spring lock washer and a specially shaped nut that creates a friction lock. The elastic clip also maintains constant tension, preventing the fastener from loosening under dynamic loads. -
Q: What is the typical lifespan of this fastening system?
A: Under normal heavy haul conditions (20–40 MGT/year), the system can last 15–20 years before replacement is needed. The clip fatigue life exceeds 3 million cycles. -
Q: Can I use this system with 60 kg/m rail or other rail sizes?
A: The current design is optimized for 100 kg/m rail. However, we can customize the rail pad and clip geometry to fit 60 kg/m, 75 kg/m, or other profiles. Please provide your rail specifications. -
Q: What surface treatments are available for corrosion protection?
A: We offer black oxide, zinc plating (yellow/blue passivation), Dacromet, and hot-dip galvanizing. The choice depends on the environmental conditions (e.g., humidity, salt spray). Dacromet is recommended for coastal or tunnel areas. -
Q: Do you provide installation tools and instructions?
A: Yes, we can supply manual or hydraulic installation tools (e.g., clip applicator, torque wrench). Detailed installation manuals and videos are available. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 1,000 sets. For customized versions, MOQ may be higher. We also accept trial orders for small quantities. -
Q: How long does delivery take?
A: Typically 20–30 days after order confirmation, depending on quantity and customization. For urgent orders, we can expedite production.
