Hanomag (Hannoversche Maschinenbau AG) was a German producer of steam locomotives, tractors, trucks and military vehicles in Hanover. Hanomag first achieved international fame by delivering a large number of steam locomotives to Finland, Romania and Bulgaria before World War I. In 1925 they added automobiles to their line, additionally moving in 1931 into the production of construction machinery. Since 1989, the company has been part of the Komatsu company.
The company dates back to 1835 when Georg Egestorff founded in Linden near Hanover a company called Eisen-Giesserey und Maschinenfabrik Georg Egestorff to build small steam engines. They soon started making farm machinery and in 1846 built their first railway locomotive for the Royal Hanoverian State Railways. By 1870 they had made 500 locomotives and in 1871 changed their name to Hannoversche Maschinenbau Actien-Gesellschaft vorm. Georg Egestorff, Linden vor Hannover. Road vehicles followed when in 1905 they received a contract for steam waggons for the German army.
Petrol engined vehicles followed in 1912 with a line of farm tractors.
During World War II, the car plant made military vehicle engines, a military version of their heavy tractor renamed the SS-100, and half track troop carriers. Hanomag 20 B, a 4-wheel-drive Small Unit-Personnel Carrier was produced 1937-1940 (ca. 2000) under the parentage of Stoewer (as the R180, R200 and Type 40). Capacity problems by Stoewer resulted in co-production by both BMW (as the 325) and Hanomag. Together the three manufacturers made ca. 10.000 units. The special 4-wheel-steering system was fitted on most models. Operating a "lock-level" between the front seats made the steerable rear axle turn sideways to a certain angle.
In 1964, Rheinstahl took over
and in a reverse of history the company was merged with Hanomag.
(Henschel & Son (German: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons.)
The farm tractor operation was sold to Massey Ferguson and in 1969 the truck making division of Hanomag-Henschel went to Daimler Benz, leaving the Hanover works making earth-moving machinery for Massey Ferguson.
In 1989, the world's second largest construction machine manufacturer, Komatsu, bought a share of Hanomag AG and since 2002 Komatsu Hanomag GmbH has been a 100% subsidiary of the global company.
