Railway
We offer locomotive and railway wagon manufacturers innovative seamless tubular solutions to reduce the weight of their vehicles. This allows significant reduction of energy consumption and substantial improvement in performance. By reducing wear and tear and overall maintenance our products support cost-effective operations of railway vehicles. One specialty in our portfolio are tubular rail axles.
Our commitment to research and development has resulted in our innovative Tubular Railway Axle. Thanks to this development, the weight of railway vehicles can be significantly reduced.
The table below shows different types of railway axles, commonly applied for iron ore wagons, and the reduction of weight that a tubular version can afford.
Even with the reduction of the weight of the tubular axle to 420kg (OFT 39U), which corresponds to the reduction of 250kg on the weight of a solid axle of 670kg, it is still expected the same performance from the 7” X 12” broad gauge solid axle.
As a consequence, the number of trips of iron ore transport trains between a mine and the harbor can be reduced.
Also other kinds of rail vehicles will benefit from tubular axles: lifetime of the whole railcar structure is increased and the load and wear on the track is reduced.
Other applications for our tubular products
- Structural elements in rail vehicles (e.g. bogies, rail car passenger compartments, central beam, frame parts for gondola cars)
- Shock absorbers (e.g. in couplings)
- Cylinder liners for diesel engines
- Hydrogen: technical equipment of trains and stations
