W14HH rail fastening system

The W14HH fastening system is designed for heavy rail traffic with a maximum permissible axle load of 350 kN.

Under the rail there is a rail seat pad of high static stiffness. The rail fastening is characterized by additional flexibility due to the central loop of the clip, which is located above the rail foot. This eliminates the possibility of overloading and plastic deformation of the clip arms and prevents rail rotation.

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
