MINEXPO HIGHLIGHTS additional feedback from the drive system, front wheels, steering, suspension and other systems on the truck to enhance the slip/slide control feature. Pitch and skid control are brand new features. "The technical barrier between the drive system manufacturer and the truck manufac- turer no longer exists at Hitachi. This traction control system takes truck performance to the next level," said Greg Smith, manager heavy and mining equipment, Hitachi Construction Machinery. "What it provides in terms of safe- ty and performance is exceptional." Hitachi Mining also introduced SkyAngle, a new camera monitoring system. The new technology, which was developed in con- junction with Clarion, takes synthesized images from several wide-angle cameras mounted on the truck and displays them in the cab. This results in a comprehensive "bird's-eye-view" of the surrounding machin- ery. In addition to the proximity of machinery, the operator can switch to a "zoom display" or "wide display" mode, enabling more com- prehensive monitoring of a wide area. "The safety benefits of the SkyAngle sys- tem are tremendous. It allows operators to quickly grasp what is occurring around the machinery, such as position of other equip- ment, service vehicles or people," said Ryan Blades, division manager, Hitachi Mining. Immersive Unveils a Solution for Operator Development Immersive Technologies has taken simula- tor training to a new level with the launch of a complete blended learning solution, which includes new tools, technologies and an extended range of professional services, such as: • SimCloud: allows mining operations to maintain complete visibility over local or global Simulation training programs via a secure website. • Global Operator Benchmarking: allows mining operations to benchmark their equipment operators against global norms based on data captured from more than 23,000 operators. • Trainer Productivity Station: is designed to alleviate the industry shortage of ex- perienced trainers. • SimDesktop: allows trainers and mana- gers to take advantage of these tools any- where, anytime. • SimMentor: SimMentor facilitates brief ing before and debriefing after simula- tion training sessions, increasing training effectiveness and freeing up simulator time. 34 E&MJ; • NOVEMBER 2012 JoyGlobal Previews New Loading Tools JoyGlobal also showcased several more examples of advancing technology that helps mines increase operational efficiency. Those included new electric shovel advance- ments, an innovative P&H; drill operator cab and new training simulators. The company also recently announced a new strategic business alliance with ESCO to develop new lip systems for shovel dippers. JoyGlobal's new hybrid shovel, the P&H; 2650CX, is a diesel-electric rope shovel with an articulating hydraulic clamshell attachment designed to deliver a 65-ton payload. The machine will four-pass load 240-ton trucks and be capable of loading ultra-class 400 ton trucks. Engineered to blend the high productiv- ity of electric mining shovels with the mobility and flexibility of hydraulic excava- tors, the P&H; 2650CX is designed to deliv- er a 15% total cost of ownership reduction when compared to large hydraulic excava- tors through a combination of reduced fuel consumption, improved availability and decreased maintenance and repair costs. "Fuel consumption will be reduced by as much as 25% through using proven power regeneration from our electric motor and drive systems technology from our P&H; Letourneau-Series Wheel Loaders," said John Koetz, vice president, product mar- keting and engineering, JoyGlobal Surface Mining. "The drive system used will be approximately 50% more efficient than comparable diesel hydraulic systems." In addition to reduced fuel consump- tion, the P&H; 2650CX will decrease the hydraulic routings, on-board fluid and pumps. This substantially improves sys- tem level reliability, efficiency and main- tainability—which can result in increased machine availability over traditional diesel-hydraulic excavators. The first machine is slated to be placed in mine in the fourth quarter of 2013. JoyGlobal also introduced the P&H; 4800XPC, the company's largest electric mining shovel, with a 135-ton payload designed to three pass load 400-ton ultra- class haul trucks. Built upon the proven performance of the P&H; 4100XPC AC, its design leverages new, patent pending Adaptive Controls technology with ultra- class machine structures to enable the larger payload and increase efficiencies. "Our new Adaptive Controls are a series of seven advanced control functions that optimize shovel power usage in different phases of the dig cycle," said Josh Wagner, director of product development. "The goal of this system is to enable the most efficient and productive dig cycle possible, regard- less of the severity of the application." In addition to the Adaptive Controls, the P&H; 4800XPC features robust machine structures and systems such as a wider boom and handle, a new dipper with a higher weight to payload ratio and a patent pending modular counterweight sys- tem. The company estimates a production increase of as much as 20% over the P&H; 4100 XPC AC with the potential to move more than 9,000 tph in production. The first machine is slated to be placed in a mine in the fourth quarter of 2013. Liebherr Introduces New Truck and Excavator Liebherr unveiled the new ultra-class T 284 as the follow-up to the successful T 282 C. The T 284 offers one of the high- est payloads in the industry and features the latest generation of the Litronic Plus AC drive system. Developed and built by Liebherr, the proven Litronic Plus AC drive system deter- mines the optimal way to extract power from the diesel engine. With this system, more power is available to accelerate the truck and climb grades. The Litronic Plus system also conserves fuel when the engine is idling. In this way it minimizes fuel con- sumption and maximizes performance. The combination of the T 284's effi- cient Litronic Plus AC drive system, its high-power engine, and low gross vehicle weight leads to fast haul cycle times with higher speeds on grade if compared to other trucks in its class. The T 284 supports engine options with power ratings up to 4,023 hp/3,000 kW. With application-specific recommenda- tions from Liebherr, mine operators can select the engine that will allow the truck to meet productivity targets while minimiz- ing fuel consumption. These engine options offer the latest fuel-injection tech- nology for cleaner combustion and reduced fuel consumption. The T 284 also supports high-capacity tires. "As the designer and manufacturer of the first 400-ton ultra-class diesel-electric mining truck, Liebherr has been at the fore- front of this successful industry solution," said Bernd Haase, executive vice president of sales and marketing, Liebherr Mining Equipment.
