VDMA 7 2018 • VDMA MINING SUPPLEMENT maintained their commitment to the mining business, retaining specialists at a time when others were downsizing. Eickhoff manufactures machinery and gearing technology de- signed to withstand extreme conditions. Those offerings range from equipment used in deep underground mines to wind turbines 100 meters above the Earth's surface. 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. 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 included 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 continuous miners for underground mining, Schalker Eisenhütte Maschinenfabrik GmbH manufactures locomotives for ore and coal mining, and meanwhile also state-of-the-art hybrid locomotives for urban underground service and maintenance applications. Eick- hoff 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 company, such as improving stan- dards for metallurgy. Hydraulic Power When it comes to experience, Hauhinco has been serving the under- ground coal mining sector for 110 years. The company was founded 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 sup- plied 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 opera- tions around the world. By the late 1980s, most of the company's business was focused on water hydraulics for mining and other industrial applications 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. Hauhinco has evolved with mining markets. In 1981, they es- tablished a subsidiary close to Pittsburgh to service a growing long- wall business in the USA. Today, they have mining and industrial partners around the world. The Hauhinco production facilities in Sprockhövel look much different today than they did 110 years ago. At peak times, 300 em- ployees were building Pickaxes and rock drills to support not only the local miners 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 manufactur- ing, but they have more sophisticated tools and they supply equip- ment and solutions worldwide. The German coal mines may be closing, Hoffmann explained, but the suppliers in Germany are still developing leading mining technology. 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 explor- ing production sites for crawler excavators and eventually settled on Colmar, France. This central location in Europe was ideal for ma- chine transportation. After the cornerstone was laid in July 1961, the Colmar site developed rapidly. As the industries for excavators expanded, the design and technology of the machines were enhanced, and the French factory became a prominent manufacturer of techno- logically advanced crawler excavators. This progressive spe- cialization lead to new business areas, one of which was min- ing-class excavators. In 1970, Liebherr took root on the North American continent. Service as well as the proximity to local customers were import- ant to Hans Liebherr, and subsequently, Liebherr-America Inc. was founded in Newport News, Virginia. The company supplied the Amer- ican market with hydraulic excavators, crawlers and wheel loaders and also represents the company's other interests. During this pe- The Eickhoff shearer loader remains a vital, progressive aspect of longwall mining. Liebherr supplies some of the largest mining equipment in the world from a network the company began to build nearly 70 years ago.
