Halfen Rail Solutions
Framing Systems
HALFEN framing channels – the flexible all-purpose assembly system. Together with the corresponding HALFEN bolts or threaded plates, HALFEN framing channels offer all the advantages of adjustable bolt connections and framing construction.
HALFEN Applications In Rail Tunnels
In this example, the rail tunnel was designed using tubbing segments. Most of the HALFEN solutions illustrated here are also suitable for use in cast-on-site concrete elements.
HALFEN Channels
- Fixing of building components to concrete elements
- Overhead cantenary systems
- Door fixings/emergency, cross passage doors
- Access walkways
- Hand rails/safety barriers
- Utility and service installations
- Signalling equipment
- Signage

HALFEN HTA-CE Cast-In Channels
Lötschberg and Gotthard Base Tunnel, Switzerland
The Lötschberg and Gotthard transit axes are at the heart of Europe’s most important freight corridor, connecting Rotterdam (Netherlands) and Genoa (Italy)—the so-called Rhine-Alps corridor. The Lötschberg base tunnel is 34.6 km long and has 174 cross-passage doors. The connections through the cross-passage doors are typically used as escape routes. The total length of the Gotthard Base Tunnel is 57 km (currently the longest tunnel in the world); it consists of two single-track tunnels with 350 sliding cross-passage doors.
The cross-passage doors are fixed to hot-rolled HALFEN Castin channels. The doors are subjected to fatigue-related stresses caused by passing trains, which can be effectively absorbed by the hot-rolled channels.
HTA-CE
Standard HALFEN Cast-in channels
HALFEN Cast-in channels are the ideal basis for easy-to-assemble, adjustable fixings. Filler strips prevent the concrete from seeping into the channel. Numerous types of secondary components can be connected or fixed to the HALFEN Cast-in channels.
APPLICATIONS:
- fixing of cross passage doors
- fixing of systems subjected to dynamic loads
