Orenstein & Koppel (O&K), formed in 1876 by Benno Orenstein and Arthur Koppel, originally specialized in the manufacture of railway equipment.
In 1981, construction equipment formed the basis of the company's product line, and the railway equipment business was sold.
At the beginning of the 20th century, O&K developed its first multi-bucket excavator, in 1908 it produced a single-bucket excavator that moved by rail.
In 1922 the first crawler-type single-bucket steam excavator was assembled. The installation of diesel engines began in 1926.
In 1934 the first bucket wheeled excavator was produced. The company also manufactured wheel and track loaders, graders, dump trucks, cranes, and other equipment.
The products were manufactured at several factories in Germany.
In 1998 O&K was acquired by the Fiat Group, and since 2005, construction equipment has been marketed under the New Holland brand. In the same year, Terex Corporation bought out the O&K mining division from Fiat.
In 2010 a line of Terex mining equipment, including Terex O&K mining excavators, was sold to Bucyrus.
In 2004 Terex and CATERPILLAR signed an agreement to sell O&K equipment through the Caterpillar network.
