bauma 2013 continued requires only half as much installation space and is also significantly lighter. Altogether, the couplings helped increase the productivity and profitability of the belt conveyor. To operate the conveyors in the most efficient way, Voith offers not only couplings, but also optimal drive solutions. The drive package solutions include the drive hardware, PLC controller and supervision of installation as well as commissioning. Integrating Power Technology for Mining Voith's TurboBelt 780 TPXL fluid coupling. the conveyor transports around 10,000 metric tons per hour (mt/h) of iron ore, reliability was a high priority. When combined with reliable mechanics, the hydrodynamic TurboBelt 780 TPXL coupling provides extremely high system availability of up to 99.8%. Maintenance concerns are minimized as the hydrodynamic power transmission is completely wear-free. Compared with traditional couplings, the TurboBelt 780 TPXL The theme for the Siemens stand at bauma was Drive Your Mining Business with Siemens. For 85 years, Siemens has been working with the mining business adapting electrical technology to meet the industry's needs. In the 1950s, it introduced the WardLeonard drive system. In 1976, they introduced AC drive systems for electric shovels, and in the mid-1980s, Siemens began to embrace gearless drive technology, installing systems on conveyors, bucketwheel excavators, draglines, and grinding mills. Today, they are looking at how they can help mine operators integrate all of their systems to meet today's business demands. If a service provider wants to help a min- ing company, it has to understand today's circumstances. "Mining projects are major investments that combine hundreds of different components and making sure all of the interfaces work well is very important," said Edzard Lübben, executive vice president-minerals, Siemens. Explaining the Siemens approach to system-wide integration, Lübben offered a traditional drive system as a starting point. "It typically has electric motors, frequency converters and gearboxes, and we make sure that everything works well within that system [horizontal integration]. Then we consider vertical integration to make sure the control logic for the drive is well-embedded in the overall plant architecture," Lübben said. "The third dimension is life cycle integration. By using sophisticated engineering tools initially for the horizontal and vertical integration, we can gather the information generated from those systems to manage operations and plan maintenance and future development." An integrated approach will save time and money. "To make these types of systems work well, you not only have to know how the drive works, but you also have to understand the application and the environment in which it is used," said Norbet Becker, vice Double Coin Tires Founded in 1934, Double Coin has been committed to meeting the demands of the global off-the-road and contractor tire needs with a wide range of All-Steel constructed radial products.
