Fastening System 300HH

The rail fastening system 300HH is designed for category E according to EN 13481-2 standard, with a maximum permissible axle load of 350 kN and minimum curve radius of 150 meters.

The system is dedicated for Heavy Haul systems on slab track.

This rail fastening system is provided with a Elastics pad of static stiffness 37.5 kN/mm ± 15 %.

Due to the mid-loop of the SKL15 clip, which is mounted over the rail foot, this rail fastening solution is characterized by additional flexibility. This eliminates the possibility of overloading the clip arms and their plastic deformation, as well as prevents rail rotation.

- Static stiffness of elastic pad 37.5 kN/mm ± 15 %
- Height adjustment in the range of -4 mm/+26 mm
- Possibility to use anti-thief screws with a triangle head shape
- All of the components can be pre-assembled
