Demag Cranes AG is a German heavy equipment manufacturer now controlled by US based Terex. The roots of Demag date back prior to its formation, but became Märkische Maschinenbau-Anstalt, Ludwig A.-G in 1906 as the biggest crane building company in Germany employing 250-300 people. The company was a manufacturer of industrial cranes that included types like, bridge cranes, hoist (device), overhead cranes, Gantry crane to name a few. In 1910 came the hour of the Deutsche Maschinenfabrik in Duisburg – known worldwide by its telegram abbreviation Demag (now ''Demag Cranes & Components GmbH''). In 1973 The Mannesmann group assumed ownership of Demag. Since that time the company has continued to grow and change. Parts of the company under core business structuring moved from its ownership to focus the main concept of the company. ==Founding== The Demag company was formed finally 1910 in Duisburg through the union of the ''Märkische Maschinenbau-Anstalt L. Stuckenholz AG'', the ''Duisburg Mechanical Engineering AG'', and the ''Benrath Machine Works GmbH''. The ''Märkische Maschinenbau-Anstalt L. Stuckenholz AG'' traces back to the machine factory ''Mechanische Werkstätten Harkort & Co.'', founded 1819 in Wetter an der Ruhr, already beginning the manufacturing of cranes in 1840. In 1908, they designed what was then the world's largest floating crane, built for Harland & Wolff in Belfast, which would be used for the building of the passenger liners RMS ''Olympic'' and RMS ''Titanic''.〔http://www.preservedtanks.com/Locations.aspx?LocationCategoryId=1155〕 Starting in 1925, Demag also manufactured excavators. They expanded to manufacture locomotives and railroad cars. During the Second World War, armoured fighting vehicles (in particular Bergepanther) were built in the Berlin Staaken plant. During the buildup to, and during World War II, Demag-designed halftrack military vehicles, such as the armored Sd.Kfz. 250, played an important role during the war, with just over 6,600 built by Demag and their subcontractors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demag」の詳細全文を読む スポンサード リンク
