Orenstein und Koppel was founded on 1 April 1876 in Berlin by Benno Orenstein and Arthur Koppel. For the first fifteen years of its existence it functioned as an iron and mechanical engineering works, entering the railway construction field in 1892. It specialised in the manufacture of narrow-gauge field service locomotives – feldbahn – for the German army and light railways used in mining and industrial settings. In 1904 the firm marketed its first bucket chain trencher, powered by a steam engine. In 1908 it acquired the firm of Gerlach und König in Nordhausen, manufacturing there petrol and diesel industrial locomotives.
During the Great War the firm provided War Ministry with all manner of railway material, including thousands of feldbahn locomotives and narrow-gauge cars. In the aftermath of hostilities Orenstein and Koppel fell upon hard times, but from 1922 it found new markets in manufacturing heavy construction equipment – power shovels, excavators, graders, wheeled loaders, road rollers and tipping lorries. With easing of market conditions in the later 1920s it resumed large scale production of railway materials – including its traditional line of narrow-gauge industrial locomotives – but also equipment for Germany’s expanding system of rapid-transit urban railway lines. It further diversified its product line by undertaking the manufacture of industrial and shipboard cranes and, with the construction of the National Motorways, Orenstein und Koppel was in the forefront of developing many of the specialist excavators, trenchers and concrete-laying machines employed in their construction.
Unlike many German industrial firms Orenstein und Koppel chose to grow through internal expansion rather than acquisition and amalgamation of other companies. Nevertheless the firm did acquire, in the latter part of the 1930s, significant holdings in two outside firms which – while maintaining formal independence – might be considered subsidiaries. In 1934 it took a half-share in the capital of the Flensburger Fahrzeugbaugesellschaft, a manufacturer of fork lift trucks and other materials handling equipment, and in 1936 it acquired the Lübecker Maschinenfabrik, a diversified machine-building firm.
In addition to its manufacturing facilities at home Orenstein und Koppel maintains an international network of sales offices and agencies throughout the world, including offices in Cleito, Madrid, New York, Rio de Janeiro and Rosario.
