Application Of E Fastening System
High-Speed Rail
On lines with speeds of 300 km/h and above, the track requires extremely high stability and geometric stability. Widely used in high-speed rail systems such as Type III (WJ-4) and Type IV elastic clips.
Heavy-Haul Railways
For ore and coal transport lines with axle loads of 30 to 40 tons, fasteners must withstand enormous vertical and lateral loads. Reinforced elastic clips such as E2009, E2055, and E2001 are typically used.
Metro & Light Rail
Metro and light rail systems are usually located in tunnels, requiring special considerations for vibration damping, noise reduction, and installation space. Metro-specific fastener systems such as DTⅢ and DTⅥ are primarily used.
Various Track Types and Special Environments Type E fasteners offer excellent compatibility, adapting to different track standards worldwide.
Sleeper compatibility: Suitable for both concrete sleepers and wooden sleepers or steel bridge decks via a base plate.
Extreme weather: E-type fasteners, treated with special anti-corrosion measures (such as hot-dip galvanizing and Dacromet coating), are suitable for coastal environments with high salt spray corrosion or high-altitude and cold climates.
Rail type: Compatible with both ballasted and ballastless tracks.
Advantages
Why choose our E-type fastener system?
Full-Scenario Adaptability
Strong Compatibility: From high-speed passenger lines with speeds exceeding 350 km/h to heavy-haul railways with large capacity, and urban subways and light rail, one system comprehensively covers all applications. It maintains superior performance in environments with extreme cold, high temperatures, high corrosion, or high traffic density.
International Standard Compliance: Meets certification requirements in multiple countries, simplifying procurement and compliance processes for cross-border projects, removing standard barriers for global EPC contractors, railway bureaus, and construction units.
Extremely Long Lifespan and Ultimate Reliability
Persistent Centering Force: The unique “E”-shaped structure of the elastic rail provides continuous and stable clamping force, firmly locking the rail and effectively resisting longitudinal creep and lateral displacement caused by train operation, ensuring long-term precision in track geometry.
Extremely Long Service Life: Based on high-quality materials (such as 60Si2MnA) and fatigue-resistant design, the system lifespan is synchronized with the track overhaul cycle, significantly reducing the risks of unexpected maintenance and train safety due to fastener failure.
Optimal Life Cycle Cost
Convenient Installation and Maintenance: Compared to traditional bolt fasteners, installation efficiency is significantly improved. Its maintenance-free nature saves operators significant labor, testing, and replacement costs.
Price Advantage: Gnee offers factory direct sales, discounts for bulk orders, and customization services.
