O&K Antriebstechnik

With over 140 years of history, O&K Antriebstechnik is a centre of engineering excellence, recognized worldwide for high quality products for applications in the mining, construction and marine & offshore industries.

Acquired by Bonfiglioli Group in 2016, this leading brand develops, manufactures and offers a full range of final drives such as slew drives, travel drives, winch drives and cutter drives.
The origins of the company date back to the founders, Benno Orenstein and Arthur Koppel, who at the end of the 19th century began – in the middle of the Ruhr – to develop railway systems for foundries and mines. Gradually, O&K became the benchmark for heavy-duty machines and the best-known brand in the world for the design and manufacture of excavators and mining shovels.

Today, O&K is recognized for its solid expertise, its capacity to adapt the design of its products depending on customers’ requirements and the high technological standards of development.
