Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railway fastening systems. Our E-type spring clip for concrete sleepers is engineered to meet the rigorous demands of heavy-haul railway tracks, delivering exceptional vibration resistance and long-term reliability. With over two decades of experience and an annual export value of US$5–10 million, we provide durable, cost-effective solutions trusted by global railway operators.
The E-type spring clip is a critical component of the elastic fastening system, designed to securely hold rails to concrete sleepers while absorbing dynamic loads and minimizing track deterioration. Its unique geometry ensures consistent clamping force, even under extreme stress from heavy axle loads and high traffic density. Below, we break down the key features and specifications.
Key Features & Benefits
- High Vibration Resistance: The clip's spring steel composition and optimized shape dampen vibrations effectively, reducing rail wear and maintenance frequency.
- Robust Clamping Force: Maintains consistent toe load (typically 8–12 kN) to prevent rail creep and gauge widening, even in heavy-haul conditions.
- Fatigue Life: Manufactured from high-grade spring steel (60Si2Mn or equivalent) with precise heat treatment, ensuring over 3 million cycles without failure.
- Corrosion Protection: Optional black oxide coating or other anti-corrosion treatments available for extended service life in harsh environments.
- Easy Installation & Maintenance: Designed for simple manual or semi-automatic installation, reducing labor costs and downtime.
- Compatibility: Fits standard concrete sleepers with rail profiles from 50kg/m to 75kg/m, customizable for specific track systems.
