W14HH rail fastening system

The W14HH fastening system is specifically designed for heavy rail traffic, capable of supporting a maximum axle load of 350kN.

This advanced system includes a rail seat pad with high static stiffness, ensuring exceptional performance under demanding conditions.

Key Features:

  • Improved flexibility: The innovative mid-loop clip design, located above the rail foot, provides additional flexibility, preventing overloading and plastic deformation of the clip arms, while effectively preventing rail rotation for increased safety and durability.

Features aspects of the W14HH fastening system:

  • Typical application - heavy haul with concrete sleepers on ballasted track
  • Axle load - max. 350kN
  • High longitudinal rail resistance - min. 9kN
  • Electrical resistance ≥ 5 kΩ
  • Clamping force for SKL14R (nominal) - 11.5 kN
  • Gauge adjustment in the range of ±10 mm
  • Optionally, the system can be fitted with an anti-abrasion pad to prevent excessive wear on the fasteners.
  • All components can be pre-assembled at the sleeper factory
