Exhibitor profile

Since its foundation in 1969, F.lli BIGARAN is specialized in the manufacture of devices and components for rolling stock. The company is organized into two divisions:

The Mechanical Technology Division designs and manufactures mainly impellers and fans, both radial and axial, for rail and industrial applications. We develop the impellers and fans using the latest design technologies such as, for example, the FEM analysis. Our company is certified according to UNI EN 15085 and our production departments are equipped with the most modern machine tools and equipment.
The Mechanical Technologies Division also provides spare parts for locomotives and railway carriages such us for example: hydraulic and mechanical driving joints, pneumatic valves and electro-valves, crankshafts, valves and cylinders for compressor.

The Insulation Technology Division designs and manufactures arc chutes for high-voltage contactors, starting from customer's drawing or sample. In addition to the above, we reclaim parts in asbestos and replace them with new generation composites or ceramic parts, which are more resistant and not harmful for health and the environment.
We are the leading suppliers of ATM – Milan for arc chutes for AT contactors and in 2009 we have started to provide them with an ASGEN chute made with our Refrarc GCS composite for the metro line 1; this has allowed them to carry out maintenance and replacement cycles after 150.000 Kilometers, instead of 25.000.

The prerogative of our company is to provide solutions to customers through the experience and professionalism of our technicians and employees.
Customers' problems, such as the unavailability of a spare part, or the short durability of the original component, are a challenge to seek new solutions, develop new products, always having as our goal the full customer's satisfaction.

  • Partnership for co-design and implementation of parts and equipment according to customer’s requirements.
  • Reverse Engineering and manufacture of components and systems according to the sample, also in small quantity.
  • Production of components and systems according to customer's technical specifications.
