The origins of Sumitomo Drive Technologies in Europe go back to the 1930s. Lorenz Braren invented the Cyclo drive in Munich and established CYCLO Getriebebau GmbH in Munich, Germany, in 1931. By registering a patent for his invention, Braren had a decisive influence on drive technology with his totally new drive concept. The Cyclo drive operates without gears; the torque transmitting parts are exposed exclusively to compressive and not shear forces. For the user of Cyclo drives this offers a considerable advantage. Sudden failures due to overload are eliminated.
After the 2nd World War Lorenz Braren took up the development of the product once more and continued to optimize the Cyclo drive until his death in 1953.
Towards the end of the 1930s, Sumitomo Heavy Industries, one of the largest mechanical engineering companies in Japan, manufactured and marketed under license the first Cyclo drives in Japan – with considerable success. In 1974, the company purchased shares in CYCLO Getriebebau GmbH.
The German company was taken over completely by Sumitomo Heavy Industries in 1994 and expanded throughout Europe, operating since 2003 under the worldwide umbrella brand Sumitomo Drive Technologies. In Europe, the company currently has over 300 employees who manufacture and market a complete range of gear mechanisms and drives.
Decades of experience and innovation, a leading position worldwide in drive and control technology combined with a worldwide presence make Sumitomo Drive Technologies a trustworthy partner for all its customers.
