Make the most of Stierli-Bieger's extensive experience in rail bending and straightening.
Transit Authorities, rail construction companies and rail factories from all over the world opt for our tried and tested professional bending solutions. The rail bending systems of Stierli-Bieger are used throughout the world, wherever professional, stationary bending is required. Continuous development and specialisation has led to this rail bending machine dominating modern rail machining. We have a very large number of excellent references.
Along with simple manual control systems, ultra-modern CNC controls with laser systems are available, which bend rails with a high degree of process reliability and automation. Even parabolic transition curves can be bent using a program.
The Stierli-Bieger concept has replaced roller bending machines in recent years. It is therefore possible to bend rails along their entire length. There is no need to cut off straight ends. Feed systems with roller conveyors and turning devices ensure problem-free transport of the rails.
The bending machine excels in all areas relating to rail construction:
Bending grooved rails
Bending Vignoles rails
Bending and straightening tongue rails
Bending full-web rails
Bending special rails
Bending rails by folding
Torsion straightening of rails
For smaller-scale rail machining, our cost-effective 820 HE or 820 CNC can be used. For typical stationary bending stations, we use the 2200 - 3300 RP/NC or 2200 - 3300 RP/CNC. For straightening large frogs, we use 440 ton or 600 ton machines.
