Demag

Demag ( German engineering corporation) was a German industrial group whose individual companies are now scattered. They can be found among others in the meantime SMS Demag AG ( subsidiary of SMS Holding ), but also at Siemens and a number of other companies.

Demag as an independent group

The Demag Group was formed in 1910 in Duisburg by the merger of Maschinenbau -Anstalt L. Märkischen Stuckenholz AG, Wetter an der Ruhr, Duisburg Maschinenbau AG, Duisburg, and Benrather Maschinenfabrik GmbH, Benrath (1896 est. ).

The Märkischen engineering institute L. Stuckenholz AG goes back to the founded in 1819 Mechanical Workshops Harkort & Co. in Wetter an der Ruhr. In 1840, they began the construction of cranes.

In this section, Demag became one of the leading companies. So you gave in 1908 to date, the world's largest floating crane (height above 40m, lifting capacity 150 t) for the Harland and Wolff shipyard in Belfast, the need this for the construction of passenger ships Olympic and Titanic and was used until the 1970s. The successor ( " Langer Heinrich", 250 t lifting capacity ) of this crane, which was built from 1913 to 1915 for the Imperial Shipyard Wilhelmshaven, exists even today ( Location: Genoa). During the Second World War, September 1942-April 1945 - - addition, locomotives, railroad freight cars, and are factory DEMAG mobile GmbH in Berlin- Staaken ( Albrechtshof ) and Falkirk armored vehicles (especially Bergepanther ) produced.

In cooperation with the Carlshütte a " crane Schaufler " was made at Duisburg in 1907. The term excavator was still the prospecting instruments subject with bucket chains. The actual construction of crawler cranes for construction sites and industrial use began in 1925 in Duisburg, before 1939, the new excavator factory in Dusseldorf -Benrath into operation. There also the first fully hydraulic excavator was developed in 1954, which can still be seen today on the premises.

Acquisition by Mannesmann in 1973

After Demag in the sector of construction equipment and mobile cranes, conveyor systems ( overhead cranes, conveyors and - retrieval systems, storage and order picking ), the iron and steel industry (complete metallurgical plants, but especially, for example, continuous casting ), the compressor and compressed air technology and plastics technology (injection ) was technically the world's leading manufacturers, the company was taken over in 1973 by the Mannesmann Group, headquartered in Dusseldorf.

In 1983, the Mannesmann Demag AG and the U.S. company Wean United Inc. of Pittsburgh, a joint subsidiary by the name of Mannesmann Demag Wean Co for the steel mill.

The following were the major restructuring of the Mannesmann Demag within:

Under Strand Construction, a joint venture with the Japanese manufacturer Komatsu in 1996 concluded that eventually completely took over the field of large excavators from the Construction section and renamed Komatsu Mining.
The range of metallurgical plant and rolling technology, headquartered in Duisburg went to Schloe - Demag (SMS ) after this division with a U.S. order to import high losses. It continues today under the name of SMS Demag.
The division compressed air technology emerged in 1996 to CompAir, then part of the British Screens / Invensys Group, but now an independent company; the former Demag Simmern / Hunsrück persists.

Currently (11/ 2010), the compressed air technology, in particular compressed air tools and motors from the company MD Pneumatic Tools GmbH & Co. KG, Stuttgart, continue to operate under the brand name MAN MANN DEMAG.

The tool company Strohm GmbH & Co. KG has bought the name Mannesmann DEMAG (ca. 2009) and initially Mannesmann Demag compressed air technology SARL & Co. KG, Stuttgart, operates. In October 2009, renamed the MD Compressed Air Technology GmbH & Co. KG was.

Plastics mechanical activities of Mannesmann Demag were later (1999 ) within the Mannesmann Group with plastics technology production by Krauss -Maffei ( in turn acquired in 1989 by Mannesmann ) merged to form Mannesmann Demag Krauss Maffei and formed the part of the Mannesmann Atecs, a holding company that included all non- telecom activities of the Mannesmann Group. The general engineering activities by Krauss Maffei and defense technology later went on Left / Hoffmann / Busch. Later this holding " MPM " ( Mannesmann Plastics Machinery ) was called with the main daughters Demag Plastics and Krauss -Maffei.

Resolution in connection with the takeover of Mannesmann by Vodafone

As of 1990, Mannesmann, who had already developed from a pure steel and tubes Group to a wide agierendem technology and engineering group, has entered with the acquisition of the D2 mobile telephone license in the Group along so far foreign field of mobile communications. This group division grew dynamically in the following years, but provoked the takeover by the British mobile phone giant Vodafone, who owned shares in D2, with the Mannesmann but on the purchase offered by " orange" in the UK came into competition.

After the takeover of Mannesmann by Vodafone, which was between October 1999 and February 2000 as economic history Crime across the stage, were all industrial activities of Mannesmann, which shortly before already as " Atecs " - were summarized " advanced technologies" to mobile and industrial activities strategically to separate, sold to a consortium of Siemens and Bosch. This consortium informed the individual companies then on, each incorporated it into the new parent companies Siemens and Bosch or selling them as part of Sachs, formerly Fichtel & Sachs, to ZF Friedrichshafen, straight on. The information presented at Atecs Demag divisions came to Siemens. It was the Demag Plastics engineering ( with Krauss -Maffei ), the Demag Demag compressor technology and conveyor technology, which included Demag mobile cranes and the company Gottwald.

By far the largest portion of the remaining extent at Siemens Demag former subsidiaries were 2001 to the American financial investor KKR resold ( see next section). The then remaining at Siemens activities were, however, largely restructured and now almost fully sold:

Thus the division of the car and mobile cranes with two plants in Zweibrücken ( Dinglerstraße and Wallerscheid ), the division handling equipment ( Dematic ) was in the changes in the division machinery part, then taken over in August 2002 by the American Construction producer Terex. The brand name Demag was first obtained in the brand "Terex -Demag ".
The part of the division handling technology, which had already been renamed as " Dematic " shortly before the sale of Atecs, namely the system and storage technology with its headquarters in Offenbach am Main, initially remained with Siemens and were whereabouts of the new name Dematic with other Siemens subregions ( " assembling " ) within Siemens continued. They first kept the name as Siemens Dematic and were then in Siemens L & A 2005 - "logistics and assembly" - renamed. Parts of the new Siemens unit " L & A" were renamed again in 2006 back in Dematic and sold to the financial investor Triton.
Other parts of the conveyor system, namely the ( non-mobile ) crane technology based in Wetter / Ruhr, were first performed by Siemens as Demag Cranes & Components (DCC ) as a limited company. So you got back to the traditional name of Demag.
The division compressor technology was renamed last Demag Delaval Turbomachinery below with locations in Duisburg, Hengelo and Trenton. The company manufactures high-performance compressors for the petroleum, chemical and general industry and sells them worldwide. It was incorporated into the Siemens Group "Power" in 2001.

Restructuring and sales by KKR

In the fall of 2001, Siemens sold the core activities of the former Demag ( Demag Cranes, Gottwald and MPM ) and a hodgepodge of other former Siemens divisions, in the case Stabilus by Mannesmann to arise to the financial investor Kohlberg Kravis Roberts & Co. (KKR ), who in operating under the name of Demag Holding S.à rl in Luxembourg summarized. At this company Siemens still held 19%. By early 2008, this Demag Holding had been able to dispose of all material business units:

The current under the name Stabilus automotive supply business (producer of gas springs (short: gas springs) and hydraulic dampers ), formerly a part of Fichtel & Sachs (formerly Mannesmann ), based in Koblenz, was sold to the private equity firm Montagu 2004.
The former Siemens divisions Landis & Gyr, a Swiss manufacturer of counters, who was called in the meantime "metering ", and Omnetica, a British IT a service provider, were also sold in 2004.
The restructuring of the Demag crane activities (DCC GmbH) led to the closure of the plant Bad Bergzabern (small hoists) and a part of the plant in Wetter (heavy industrial cranes, called " Process Cranes " ) as well as extensive staff reductions. 2006 Demag Cranes was then, together with the traditional port crane manufacturer Gottwald ( formerly Mobile Cranes ), who was at Mannesmann times associated with the vehicle crane Zweibrücken, as DC AG ( Demag Cranes AG ) on the stock market. Since autumn 2011, the DCC is part of the Terex Group, which has taken over the majority of the shares. At this time include Demag Cranes & Components, Gottwald and KSR ( Kranservice Rheinberg ) for DC AG.
The Plastics Technology operates under the name MPM ( Mannesmann Plastics Machinery ), today as Krauss-Maffei. At the holding company include Demag Plastics Group, the Krauss -Maffei Plastics Technology, Munich, Netstal Maschinen AG, Naefels, Switzerland, and the Berstorff GmbH, Hannover. The activities in plastics engineering of today's Sumitomo (SHI ) Demag, which is headquartered in Schwaig, a small machine factory in Wiehe, production facilities in Ningbo ( China) and a joint venture in Chennai ( India) manufactures injection molding machines. The location in Strongsville (Ohio, USA) was closed in 2007 and now acts solely as a service location. The entire field of plastics technology in 2006 to another private equity firm, Madison Dearborn, resold. 2008 Investor Demag Plastics Group, which was then taken over by the Japanese group Sumitomo sold.
The company part Argillon ( Technical Ceramics, meanwhile operating under the name of " Ceramics", formerly a part of Siemens) was sold in December 2007 for 214 million euros to Johnson Matthey in the UK.

Economic History of importance is the restructuring of Demag Holding by KKR, as they Franz Müntefering 2006 initiated "locusts debate" triggered, among other cases.
