in 1932 through the merger of the mechanical companies Bolinder and Munktell. Bolinder are also well known as manufacturers of 'Semi-Diesel' or 'Hot bulb' engines. In 1950 BM was bought by AB Volvo. In 1973 the company changed its name to Volvo BM AB and then in 1995 to Volvo Construction Equipment. The product range has changed with the times. Up to the beginning of the 20th century agricultural machines such as threshers were an important product.


Products


Marine engines

Bolinder produced a wide range of marine engines, mostly of the semi-diesel hot bulb type. Some of those sizes proved to be ideal in narrow boats, and some Bolinder motors so used are still in use. When starting, the cylinder head has to be heated with a kerosene blowtorch to get the hot bulb heated, and to be able to start the combustion process.


Tractors

Tractor production commenced in 1913, with the type 30-40. Tractors were the main product up to the 1970s, and gained an unsurpassed reputation for durability.


Aircraft engines

During World War II, Bolinder-Munktell, at the request of the Swedish authorities, built
Daimler-Benz DB601 The Daimler-Benz DB 601 was a German aircraft engine built during World War II. It was a liquid-cooled inverted V12 engine, V12, and powered the Messerschmitt Bf 109, Messerschmitt Bf 110, and many others. Approximately 19,000 601's were pr ...
aeroplane engines under licence. An entire underground factory at Eskilstuna was built to accommodate this factory. Owing to the superior reliability of the Swedish-built engines the Swedish airforce issued instructions that for two-engined aircraft, at least one engine should be a Swedish built unit.


Construction equipment

From the 1950s new products in the construction equipment and forestry machinery categories emerged. These were initially based on the tractor chassis. Soon the construction equipment became the dominant product range and remains so today. Products developed in the 1960s, and still in production, are wheel loaders and articulated haulers.


History

Bolinder-Munktell traces its origins to the engineering workshops ''Munktells Mekaniska Verkstad AB'' (established in Eskilstuna by Johan Theofron Munktell in 1832) and ''J. & C.G. Bolinders Mekaniska Verkstad AB'' (established in Stockholm by Jean and Carl Gerhard Bolinder in 1845). In 1950 the main shareholder Handelsbanken sold its shares to Volvo who turned the company into a subsidiary.
