VDMA 47 2018 • VDMA MINING SUPPLEMENT Excavating Evolution Within Komatsu Ltd., Komatsu Germany GmbH's mining division is re- sponsible for the development, production and marketing of super large excavators from its factory in Düsseldorf, Germany. The company traces its history to the early 20th century. In 1907, Carlshütte AG built the first electrical driven rope shovels for an open-pit mine in Lizenz controlled by DEMAG (Deutsche Maschinenbau AG). In 1925, Carlshütte AG was taken over by DEMAG, which relocated the company to Duisburg. The plant in Düsseldorf where production continues even today was built in 1939. Over the years DEMAG has continually set new milestones in the global mining branch. In 1949 the rope shovel BL 335 was the biggest rope shovel in the world and during the 1954 industrial fair in Han- nover, DEMAG sensationally introduced the world's first fully hydraulic diesel driven excavator. Moreover, in 1972 DEMAG developed the first hydraulic excavator with a total machine weight of more than 100 tons. In 1978 DEMAG was integrated into the Mannesmann trust and was renamed Mannesmann Baumaschinen GmbH. With the introduction and inauguration of the world's biggest hydraulic excavator, weighing more than 500 tons, we continued to maintain a pioneering role in the global mining market. In 1999, Komatsu acquired Mannesmann Baumaschinen GmbH by KLTD and the renaming of the company in Komatsu Mining Germany GmbH. The mining-class excavators were paired with Komatsu's existing line of haul trucks. More recently, Komat- su Düsseldorf and Komatsu Hanomag in Hannover merged to form Komatsu Germany GmbH with the mining and construction divisions. "Today we are a global player in mining with an enormous market share of about 30%, expanding and strengthening our worldwide lead- ing position as a manufacturer of extra-large excavators for open pit mining," said Dr. Norbert H.H. Walther, president and managing director, Komatsu Germany GmbH. Today, the company's shovels are working all over the world, oper- ating day and night under the toughest of conditions. At the 110,000 m 2 production plant, located to the south of Düsseldorf, Komatsu Ger- many's mining division produces five different types of mining-class ex- cavators with machinery weights of 250 metric tons up to 760 metric tons. Depending on each model, the size of the bucket varies from 16 m 3 to 42 m 3 on the PC 8000. Mine Rescue For centuries, the only protection miners had against carbon dioxide was a cloth mask soaked in vinegar. Those days have long passed, yet they gave profound impetus to a new era in safe mining technology. At the start of the 20 th century, Dräger's founder, Johann Heinrich Dräger, was motivated to develop an oxygen-compatible pressure re- ducer. He knew that, "carbon dioxide causes death, and oxygen causes life." Along with his son, Bernhard Dräger, the company was the first to envision using this technology in underground operations. Their vision and innovation gave birth to the first closed-circuit oxygen rebreather. At that time, this was breakthrough technology. In 1906, tragedy hit the French town of Courrières, when more than 1,000 miners lost their lives as a result of a firedamp explosion. In the memoires of Elfriede Dräger, Bernhard's wife, she recollects, "There he [Bernhard] saw our equipment being used by the Pompiers [firefight- ers]. Never was the fellowship between people that arises from rescue work demonstrated to me so clearly as it was during those days in Courrières." This heroism and fellowship under dire circumstances took a life of its own. At the 1911 National Mining Contest in Pennsylvania, most rescue miners wore Dräger rebreathers—to support, protect and res- cue miners underground. They called themselves "Drägermen," heroes to underground miners. It is interesting to note that even Superman needed Drägerman's help in a 1938 comic. After five generations, this name runs deep into the heart of the Dräger family, "It makes me very proud that the collaboration between Dräger and the mine rescuers is a kind of symbiosis. This is illustrated by the English word "Drägerman." (Stefan Dräger, CEO). For more than 110 years, Dräger has been a permanent and trust- worthy partner in the mining industry. Dräger mine rescue equipment, such as the BG 174 Model introduced in 1966, became an industrial standard used by miners worldwide. The company's commitment to innovative technologies in mining is largely due to its close collaboration with its customers — the miners themselves. This spirit of working together has resulted in safe and practical solutions for mine rescue teams around the world facing today's challenges. Pump Engineering In 1947, Wilhelm Abel founded a mining engineering company in Düsseldorf, specializing in the manufacturing of pumps for the coal mining industry. Today, ABEL GmbH, a subsidiary of Hillenbrand Inc., is headquartered in Büchen, Germany, and it designs and man- ufactures a wide range of pump products including membrane, solids handling, high-pressure and marine pumps. ABEL pumps are still used in mining, as well as wastewater management, the energy industry and other sectors. ABEL GmbH is considered a specialist for abrasive media and they sell their pumps worldwide. "It is, for me, a particularly exciting task to make, over the next years, a successful made in Germany company become more successful in the emerging economies worldwide," said Jaak Palisaar, managing director, ABEL GmbH. When it comes to transferring difficult copper excavation material in Chile or highly concentrated fly ash in India; the HMQ series represents the ideal pump for the reliable transfer of large volumes of abrasive and aggressive slurries under high pressure. The ABEL staff worked very hard to make the success story of this HMQ pump hit a new milestone. In fact, just in time for the company's 70 th anniversary, the 100 th pump of this product series was shipped to India. The usual reliability expected from Germany and its comprehensive customer service have been the main arguments presented to the cus- tomers of the Asian subcontinent to convince them to use ABEL pumps. For more than 100 years, the deargermen has rescued miners.
