Who we are
"WE ARE WORKING ON THE ACHIEVEMENTS" Grueber springs, this name stands in the rail industry worldwide-conformal and repeatable quality steel springs. With 180 employees, produces Grueber per year, approximately 9000 tons of steel springs and bent parts, and achieves a turnover in 2012 of about 34 million euros. A quarter of the production is for the rail industry. Well-known international manufacturers of railway equipment put on the quality of Grueber springs. Thus, at the booth this year to see springs for the • double-decker Stadler - DOSTO, • the Italian high speed train Frecciarossa 1000 (Bombardier / AnsaldoBreda) • the Siemens trains Lastotschka for the Olympic Winter Games in Sochi, • coaches of Indian Rail, • and the tilting ICEs of Alstom, which are set in a DB. Of special requirements for the space over low-temperature resistance to extreme corrosion protection requirements solutions are presented that Grueber has worked with its customers. A brand new development in the field of web application are heavy springs from inconstant wire. This construction enables a progressive course of the spring characteristic. In operation, the trains at low loading are soft suspension, whereas with increasing loading the suspension is harder. The resulting pressure force of a spring differs depending on the position of the spring ends from getting on the geometric center line. Under load, the springs have a tendency to shift vertically. Accurate measurements of the transverse deflection and paired set of springs with the same behavior ensure in the primary spring stage uniform load distribution in the bogie for optimum quality and high safety against derailment and ensure in the secondary suspension stage for a symmetric status of development on the bogie to comply with the allowable light room. Move rotary motion of the bogie in curves and traveling through switches the secondary spring is forced into an S-shape.Nevertheless, the spring coils should not touch and do not lift the spring ends. Extensive testing methods ensure at Grueber for the safe operation of the component spring in practical operation.
