VDMA 100 years, MTU and its predecessors have continually been on the forefront of technological progress, the company states, meeting OEM's needs for power, efficiency and service life in demanding operating environments. With a portfolio ranging from 100 to 3,000 kW (134-4,000 hp), MTU provides propulsion solutions meeting current and future domestic and international emissions standards—pushing engine technologies that enable international mining and construction companies to operate heavy diesel-powered equipment in any market around the world. MTU says that over the few next years, it will be launching solutions to meet the extremely stringent limits set by the EU Stage IV and EPA Tier 4 final requirements for nitrogen oxides and particulate emissions. From 2014, it will be introducing its new Series 1000, 1100, 1300 and 1500 engines, with outputs ranging from 100 to 460 kW (134-616 hp). Based on Daimler technology, these units have been specially developed for off-highway applications. They will utilize an SCR exhaust after-treatment system to achieve emissions compliance, and need no diesel particulate filters to achieve any further particulate reduction. In the power range above 560 kW (750 hp), MTU's program will be extended to 730 kW (980 hp) with the introduction of its Series 1600 engines in 2014. These will meet EPA Tier 4 final specifications applicable from 2015 without the use of any exhaust gas after-treatment. MTU notes that it placed particular emphasis on optimizing the combustion process in order to minimize fuel consumption. Overall, customers will benefit from an integrated system with low rebuilding and operating costs, it says. For power requirements up to 1,163 kW (1,560 hp), MTU is developing a new generation of its Series 2000 engines. Scheduled to be introduced in 2015, these engines will meet then-current emissions regulations without requiring after-treatment, additives or related infrastructure. The company will also introduce the Tier 4 final version of its Series 4000 engine for the mining industry in 2015. Built on the foundation of its Series 4000 Tier 2 engines, the new design combines years of experience with the latest emissions-reduction technologies, MTU says. It also incorporates the product requirements of the major mining OEMs, as well as input from end-users. To meet EPA Tier 4, the engine's technology package includes high-pressure common-rail fuel injection and two-stage turbocharging with an adjustable highpressure stage and exhaust-gas recirculation. A Successful Provider of Winder Solutions With its origins dating back to 1871, and more recently an offshoot from the mining logistics division of Siemag GmbH, Siemag Tecberg has been an independent company since 2007. Today a leading specialist in mine hoisting technology, the company's product range covers the complete field of equipment required for the operation of mine winders. Besides the winders themselves, it supplies auxiliary equipment for rope handling, rescue purposes and mine cooling. The design and development of all of its products is based on expertise that the company has accrued during the development and construction of more than 200 complete systems and 1,000 winders. Siemag Tecberg says that many of the world's leading companies from the mining and energy industries rely on its systems, with its 140 years of experience forming the basis for many successful project references all over the world. Long-term customer-orientated support has laid the foundations for continuous technological improvements and developments related to its systems and equipment, the company adds, noting that it holds more than 50 international patents and authorised components according to BVOS regulations. During 2012, Siemag Tecberg signed two contracts for the supply of mine winders to customers in China, as well as delivering a custom-designed mobile winch system for use in shaft inspections and mine-rescue operations. In June, it won an order from Lu'an Group for the design, manufacturing, delivery, installation, commissioning and service of two hoisting systems for the 8 million mt/y Gucheng coal mine. Siemag Tecberg is working with Siemens on the project, which is the 10th system that the company will have supplied to Lu'an since its first contract from the company in 1988. Siemag Tecberg has supplied more than 1,000 mine winders. VDMA 52 VDMA MINING SUPPLEMENT • 2013
