The ZEMAG (formerly Zeitz iron foundry and mechanical engineering AG ) is a German mechanical engineering and plant construction company headquartered in Zeitz , Saxony-Anhalt .

The company is primarily known as a manufacturer of machines, plant components and special vehicles for the coal and steel industry , especially the coal industry .

history

Foundation and growth (1855–1945)

Share of the Zeitzer Eisengießerei und Maschinenbau-AG in November 1941 in excess of RM 1000

The company was founded in 1855 as a small machine shop under the company Schäde & Co., iron foundry and mechanical engineering business (later iron foundry, machine and boiler factory ) with initially only ten employees. The founder and technical director was the engineer Hermann Schäde ; Compagnon was the sponsor of the Zeitz city councilor Ludwig Lange.

Due to the increasing industrialization in the surrounding central German lignite and industrial area , the young company grew rapidly and produced equipment, machines and apparatus for the factories in the region. On December 31, 1871, the company was converted into a stock corporation under the name Zeitzer Eisengießerei- und Maschinenbau-Actiengesellschaft (ZEMAG) .

From the 1870s onwards, ZEMAG developed into a leading supplier of equipment for briquette factories , in particular coal mills , coal dryers and briquette presses . As a licensee of the inventors Robert Jacobi (presses) and August Schulz ( tube dryer ), ZEMAG was the exclusive manufacturer of this technology and played a key role in the further development of the products.

In 1899, ZEMAG founded a branch in Cologne-Ehrenfeld , from which primarily the numerous briquette factories in the Rhenish lignite district were supplied.

At the beginning of the 20th century, ZEMAG already had more than 1200 employees at its two locations.

To secure its sales markets, ZEMAG concluded a cartel agreement in 1911 with its main competitor, Maschinenfabrik Buckau , which was renewed in 1922 and 1932.

Up until the Second World War , the product range was continuously expanded. ZEMAG supplied complete briquette factories, but also other machines and systems for coal extraction and processing as well as for the other raw materials industry at home and abroad. General steel construction was also part of the program; Most recently, for example, ZEMAG worked on the repair of war damage to the Zeitz Auebrücke in 1945 .

Development during the German-German division (1945–1990)

VEB Zemag in the GDR

The situation of ZEMAG changed abruptly after the Second World War due to the occupation of East Germany by the Red Army in 1945. In June 1946, the main factory in Zeitz was expropriated without compensation by the Soviet Military Administration in Germany (SMAD) and went within the scope of the reparation payments to be made into the property of the USSR. The Soviet General Directorate continued to run ZEMAG as a Soviet joint-stock company (“SAG-Betrieb”) .

At the beginning of 1954, ZEMAG became a state-owned company (VEB). According to a strategic plan of the Council for Mutual Economic Aid (RGW) within the framework of the national coordination in the Eastern Bloc , VEB Zemag Zeitz became the most important company for the planning, construction and equipping of lignite briquette factories in the GDR and in neighboring socialist countries ( ČSSR , USSR , Hungary , Bulgaria , ...). The VEB Zemag Zeitz built numerous briquette, but also coal plants for power stations and pelletizing for potash .

From the 1960s onwards, the construction of excavators and cranes was added as a second important pillar alongside coal technology . The VEB Zemag Zeitz made as part of the work for the Combine TAKRAF various Universal excavators , crawler cranes, truck cranes and tower cranes in large numbers, first to foreign specifications (eg. As the VEB heavy machinery NOBAS Nordhausen ), and later to its own design.

In the 1980s, VEB Zemag Zeitz had around 2500 employees; This made Zemag the second largest employer in the industrial city of Zeitz.

Zemag in West Germany

After the expropriation of the business assets in East Germany, the West German branch of ZEMAG in Cologne-Ehrenfeld was continued as an independent company from 1950. However, the factory was completely destroyed during the war. The company, which has now been run as a subsidiary of the Buckau R. Wolf AG machine factory, which has also been relocated to West Germany, was only involved in property management at least in 1963 and acted as the client for company apartments for Buckau R. Wolf AG. In 1968 the company moved to Neuss and in 1975 to Grevenbroich . With the closure of many coal mines and the associated briquette factories, the company ran into increasing economic difficulties in the 1970s. In 1983 the company was closed. After it was completely wound up, the company went out in 1986.

Development after reunification (from 1990)

After the reunification of the GDR and the reunification , VEB Zemag Zeitz was privatized in 1990 and ZEMAG GmbH was created. Despite rationalization measures and massive job cuts, however, it was not possible to make the company profitable in the long term. At the beginning of 2001 the ZEMAG GmbH went bankrupt .

In the same year the company ZEMAG-01 GmbH was founded with a significantly reduced workforce . Even this attempt did not prove to be sustainable in the long term, and this company also went bankrupt in 2004.

Since August 4, 2008, a new machine and plant construction company has existed again under the company ZEMAG Maschinenbau GmbH and then ZEMAG Clean Energy Technology GmbH , based near Zeitz (in the Zeitz industrial park in Elsteraue , district of Tröglitz ), which would like to continue the tradition of ZEMAG .

Products

Machinery and equipment

Initially, ZEMAG (or Schäde & Co ) built a wide variety of machines and devices, including steam boilers and machines .

For most of its history, ZEMAG primarily developed and built equipment for lignite briquette factories, but also for other industrial plants that processed coal or similar bulk materials, e.g. B. Coal-fired power plants , coal- burning plants , processing , loading and bunkering facilities.

The components manufactured included:

... each with the associated steel structure and accessories.

Excavators and cranes

Based on experience from the construction of loading bridges for coal, VEB Zemag Zeitz also built the following cranes and excavators in series production in large numbers for the needs of the USSR, the GDR and other countries worldwide:

  • Universal excavators of the 2.5 cubic meter class (types UB 162, UB 162-1, UB 266, UB 1412, UB 1412-1 and UB 1413 )
  • Crawler slewing cranes with a load capacity of 25 to 63 tons (types RDK 25, 250-1, 250-2, 250-3 , 280, 280-1, 300, 300-1, 400, 500, 500-1, 630, 630-1 )
  • Self-erecting tower cranes with load capacities 1 to 3.5 t (types Movilift 100 to 400 )

Furthermore, fully hydraulic mobile cranes with lattice boom equipment (25 t load capacity) and telescopic boom (20 t load capacity) were designed and functional models manufactured; However, for political and economic reasons, these did not go into series production.
