Scania Mining Offers Experience and Flexibility Scania has gathered all of the experience gained during more than a century in the heavy vehicle industry to provide a range of attractive solutions for the mining business. In addition to specialized mining trucks, the line of vehicles also includes buses for crew transport, engines to power mining equipment and gensets, as well as container-based field workshops for onsite servicing and training for drivers and service staff. Smaller mines and extensions from existing mines often lead to longer transport routes from the mine to the processing plant. This provides an advantage for smaller, less expensive "road trucks" that are considerably more fuel-efficient than bigger machinery that may consume 50 to 60 liters/hour. The corresponding figure for a Scania truck is generally less than half. Trucks of the size that Scania offers have benefits that affect cost and productivity. For on-site transport, smaller trucks have significant advantages since they can operate on narrow roads that are less expensive to build and maintain. They also provide extra flexibility in transport capacity. For outbound haulage, they can run on public roads if required. Scania offers solutions for every stage in mining, from exploration to reclamation and everything in between, starting with rigid dump trucks up to 46 mt for in-pit mining or moving out with 120-mt outbound combinations. Scania's field workshops are based on a modular container system that can be put into operation a week or two after a concrete foundation has been laid, a concept that has proved its worth in many countries worldwide. Driver training is part of the Scania offer, with a potential to contribute valuable fuel savings, as well as reduced wear and tear. The training can be adapted to suit local conditions and the level of driver competence. Scania can also tailor financing, leasing and rental solutions to suit operators' needs. and Asia. Underground miners would use a Putzmeister SPM 4210 concrete spraying equipment, in conjunction with the Mixkret 4 to complement the concrete spraying process. The machine is optionally available with an additive tank for transporting and transferring additives to the shotcrete equipment, enhancing site logistics. The low-profile unit provides a concrete capacity of 4 m3 and is equipped with a 6cyliner, 130 kW (174 hp) engine, which provides it with a great traction and driving capacity as well as the possibility to work at high altitudes. The cabin, mounted in machine direction, and the night vision camera at the rear, facilitate its maneuvering and ensure visibility conditions at all times. Its compact design and state-of-theart axles, both used for steering and driving, provide mobility and maneuverability in narrow galleries and tunnels. The machine has hydrostatic transmission with a stepless variable gear motor, which ensures an ideal torque:speed ratio. It also features an auto- Low-profile Concrete Mixers Putzmeister's latest concrete mixer for mining operations, the Mixkret 4, was launched last year and is already in use at several mining projects mainly in South America www.e-mj.com MARCH 2013 • E&MJ; 55
