Technical
Specification of the W14 Fastening System

• Typical Application - Ideally suited for high-speed and conventional rail networks featuring robust concrete sleepers on durable ballasted tracks.
• Axle Load - Designed to withstand a maximum threshold of 260kN, ensuring long-term performance.
• Speed - Exceptionally suitable for High-Speed (HS) railways operating at ≥ 250km/h and Conventional Rail (CR) networks at ≤ 250km/h.
• High Rail Longitudinal Resistance - Provides a minimum of 9kN to ensure unwavering stability under dynamic conditions.
• Electrical Resistance - Surpasses 5 kΩ, offering superior insulation to safeguard against electrical disturbances.
• Clamping Force for SKL14 (Nominal) - Ensures secure fastening with at least 9kN of clamping force.
• Gauge Adjustment - Offers a flexible adjustment range of ±10mm, accommodating a variety of track configurations.
• Rail Pad Material - Engineered from high-quality EVA to provide optimal durability and performance.
• Enhanced Security - Includes the option to use anti-theft screws with uniquely designed triangular heads for added security.
• Pre-Assembly - All components are expertly designed for efficient pre-assembly at the sleeper factory, streamlining installation.
