VDMA 45 2018 • VDMA MINING SUPPLEMENT arduous conditions. While experience and service are a big part of the company's success, they also have their own foundry where they have developed special alloys and they have maintained their commitment to the mining business, retaining specialists at a time when others were downsizing. Eickhoff manufactures machinery and gearing technology designed to withstand extreme conditions worldwide, explained Paul Rheinländer, CEO for the Eickhoff Group. "Those offerings range from equipment used in deep underground mines to wind turbines 100 meters above the Earth's surface," Rhinelander said. From the beginning, the engineers at Eickhoff were pioneers in the fi eld of mechanical engineering. The foundry established by Carl Eickhoff in 1864 has become a high-tech company, located in the heart of the Ruhr Valley and at two additional production sites in Germany. "This continuity enables us to develop our products and services for a global market," Rheinländer said. Eickhoff has adapted with time. Many in the mining industry recognize Eickhoff's line of equipment, which is used for cutting soft rock such as coal and potash. The company's wealth of experience has been very helpful in other markets too. Long ago, it recognized developments, which not only include the growing need for energy and raw materials, but also the trend toward urbanization and the demand for renewable energy. Eickhoff Bergbautechnik GmbH produces shearer loaders and continu- ous miners for underground mining, Schalker Eisenhütte Maschinenfab- rik GmbH manufactures locomotives for ore and coal mining, and mean- while also state-of-the-art hybrid locomotives for urban underground service and maintenance applications. Eickhoff Antriebstechnik GmbH has entered an important market with the manufacture of gearboxes for wind turbines. Eickhoff Gießerei GmbH and Eickhoff Maschinenfabrik GmbH develop new materials and processes for all areas of the compa- ny, such as improving standards for metallurgy. Hydraulic Power When it comes to experience, Hauhinco has been serving the un- derground coal mining sector for 110 years. The company was found- ed in 1908 in Sprockhövel, Germany, as Hausherr, Hinselmann & Co. During those times, it made the pneumatically powered Pickaxe, a major mechanical improvement for coal miners, and Hauhinco supplied more than 400,000 of them. Hauhinco continued to expand its mining portfolio, adding rock drills, conveyor belts, chutes and other products. In 1964, it began building high-pressure pumps for longwall mining operations around the world. By the late 1980s, most of the company's business was focused on water hydraulics for mining and other industrial applica- tions and they were developing entire system solutions. Beyond the high-pressure plunger pumps and valves, they were looking at the hydraulic network and where they could make improvements. Today, the Hauhinco name is synonymous with water-hydraulic systems for longwall mining. And, they have evolved with mining markets. In 1981, they established a subsidiary close to Pittsburgh to service a growing longwall business in the USA. Today, they have mining and industrial partners around the world. "Wherever there is a longwall market, you will fi nd Hauhinco," said Holger Hoffmann, general manager, Hauhinco. "We are the leading supplier for high pressure water hydraulic applications and we are developing new solutions here in Germany." The Hauhinco production facilities in Sprockhövel look much differ- ent today than they did 110 years ago. At peak times, 300 employees were building Pickaxes and rock drills to support not only the local min- ers extracting coal in the Ruhr Valley but also to mines in neighboring countries. Today, the company's engineers and factory workers have the same level of commitment to quality manufacturing, but they have more sophisticated tools and they supply equipment and solutions worldwide. "We have made a signi fi cant investment in our manufacturing and testing machinery during the last three years," said Christopher Durst, strategic marketing man-ager, Hauhinco. "Tolerances today are tight and to meet production standards, we need to use the most modern equipment." The German coal mines may be closing, Hoffmann explained, but the suppliers in Germany are still developing leading mining technolo- gy. Following the mining industry's needs, Hauhinco has evolved from a component supplier to an engineering company over the last 110 years. Of Cranes and Mining Equipment Hans Liebherr founded his company in 1949 Hans Liebherr Maschinenfabrik (engineering works), in Kirchdorf, Germany, to supply tower cranes to ports. By the end of the 1950s, Liebherr had introduced companies in Ireland, South Africa and Austria to expand the organization beyond its own borders. The company began exploring production sites for crawler excavators and eventually settled on Colmar, France. This central European location in Europe was ideal for ma- chine transporta- tion. After the cor- nerstone was laid in July 1961, the Colmar site de- velops rapidly. As the industries for excavators ex- pand, the design and technology of the machines are the Elckhoff shearer loader remains a vital, progressive aspect of longwall mining. Liebherr supplies some of the largest mining equipment in the world from anetwork the company began to build nearly 70 years ago.
