KE1/2 and KE1/4 rail fastening systems

The KE1/4 and KE1/2 systems are designed for ballastless tracks. The KE1/4 system is designed for fastening categories C and D, while the KE1/2 system is designed for fastening category D according to the EN 13481-5 standard.

The KE1/4 and KE1/2 systems meet all the requirements of the EN 13481-5 standard.

The system ensures low static stiffness.

Technical aspects of the KE1/2 and KE1/4 systems:

Typical applications - conventional rail, urban rail, tunnels and viaducts on ballastless track
Axle load - max. 260kN
Speed ≤250km/h
High longitudinal rail resistance - min. 9kN
Clamping force - 18 kN ÷ 19 kN
Gauge adjustment in the range ±10 mm with 1 mm steps
Electrical resistance ≥ 5 kΩ
Regulation of the vertical position by means of adjustment pads
The use of nuts with non-standard polyamide inserts makes it difficult for unauthorized persons to dismantle the system
Static stiffness of the system in the standard version: up to 25 kN/mm (it is possible to adjust the static stiffness according to the customer's needs)
