develops transport systems to move people and materials swiftly and safely in these hazardous underground environments. To make the next generation of these systems a cleaner ride, Becker-Warkop upgraded its hydraulic pack to a Tier 3/Stage IIIA emission standard with a John Deere PowerTech™ E 6.8L engine. More than 30 John Deere-powered systems have been sold worldwide already and new, compact designs are in the works. Becker-Warkop Sp. z o.o., headquartered in Swierklany, Poland, is a leading producer of underground transport systems made for coal mines, where methane and coal dust pose explosion hazards. Building on 30 years of experience and a commitment to constant improvement, the company designs mining solutions which combine the highest safety standards “Our systems let contractors move materials faster and safer, so they can increase their development of coal seams while saving on labor and maintenance costs,” says Mateusz Koc, international sales department manager. Next-generation of underground transport power Finding the most suitable solution for the customer is one of the biggest challenges for Becker-Warkop. “Underground conditions can vary a lot: heat, dust, moisture. We constantly challenge ourselves to develop continues. Becker-Warkop uses a single power pack in its “For our next generation of diesel-driven systems, our focus was on optimising key aspects, including fuel from experience that for the ‘ideal’ diesel engine, a power ratio of 150 kW (200 hp) power would be optimal.” which is crucial in mining applications,” explains Koc.
Know-how, experience, reliability Becker-Warkop does everything product. “Our motto is ‘Know-how, experience, reliability’,” explains Koc. During design and development of the power pack, local John Deere engine distributor Techbud proved to be a true asset. “They gave us all the technical documentation and 3D models and were closely involved in the process. These guys are amazing; engaged in our product and committed to helping us market a product that customers,” Koc says. “They visited us often during the development stage, and always answered our questions quickly. Plus, they gave great feedback and techniThanks to the transport system’s success, Becker-Warkop now produces seven new units each month. “The John Deere advantage is more than technical,” Koc notes. “Our underground transport systems are used all over the world, and the well-developed John Deere support network gives us and our customers reassurance and peace of mind.” This success certainly isn’t slowing down Becker-Warkop’s commitment to expanding its range of products. A compact system is currently being developed, which will be powered by a smaller capacity John Deere engine. The John Deere PowerTech™ E 6.8L
*Prime: 139-193 kW (186-259 hp) @ 1500 - 1800 rpm *Dual frequency available The John Deere PowerTech E (2-valve) 6.8 L engine features 12 -valve head (2-valves per cylinder). It has a multiple injection strategy which includes two small preinjections prior to top dead centre followed by the primary injection. Key features of the PowerTech Plus engine include a variable geometry turbocharger (VGT), 4-valve head, high-pressure common rail (HPCR) fuel injection, and cooled EGR all providing the ability to accomplish faster torque rise with fuel or exceeds previous John Deere models as well as those of the competition, says the company. John Deere uses the horsepower rating standard 97/68 EC, because it is the most widely used in Europe by the most manufacturers for various regulations. John Deere is a trusted provider of generator drive engines worldwide. For reliable power from 40 to 416 kW (54 to 558 hp), John Deere generator drive and constant-speed auxiliary engines deliver quiet operation and low vibration, reports the company. www.deere.co.uk
