Hamm AG

Hamm AG is a German worldwide manufacturer and marketer of road rollers based in Tirschenreuth, Germany. It is a subsidiary of Wirtgen Group.

Brothers Anton and Franz Hamm, who were gunsmiths, founded the company in 1878 to build agricultural equipment. The company built their first diesel-powered road roller in 1911, from a design by a second-generation Hamm, Hans Hamm. This was at a time when most rollers where steam powered. In 1928 the company abandoned all other product lines to concentrate on road rollers. Hamm produces the first all-wheel drive-all-wheel steering double-drum, tandem roller and soil compactor with vibration(Unbalance mass principle) in 1932, and retains patent protection rights until 1970. The company introduced an all-wheel steering and all-wheel drive rubber-wheeled roller in 1963, and then rolled out its oscillating vibratory roller in 1989.

In 1999 the Wirtgen Group GmbH announced that it would purchase Hamm AG, and the transaction was completed in March 2000.

History

Coat of arms

The coat of arms has been in use in its present form for about 750 years. It shows the markish chessboard ("märkischen Schachbalken") in red and silver on a golden field. Originally it was the founders' coat of arms, i. e. the Counts of Mark. The chessboard and the colours are often displayed in the coats of arms of further towns founded by that family line. Similarly, the colours of the city are red and white.

Overview

The name Ham means "corner" in the old Low German dialect spoken at that time. In the old times the name thom Hamme would be used, which evolved slowly into its modern form Hamm. The name derives from the description of the Hamm's location in the corner of the Lippe river and the narrow Ahse affluent, where it was founded on Ash Wednesday in March 1226 by Count Adolf I of the Mark.
