ROLLOUTS Vocational truck Underground truck goes electric Atlas Copco offers a suite of seven underground loaders and trucks that use electricity as the primary power source. The Green Line, it says, is designed to help underground mines address challenges including energy efficiency, carbon emissions, and environmental footprints. Underground mine trucks include the EMT35 and the EMT50 (pictured), with respective loads of 35 and 50 tons. Said to be twice as fast as any diesel truck of similar size, the manufacturer touts the trucks as the "world's most productive trucks." By using electricity, energy consumption is reduced by up to 70 percent. Regenerative braking returns energy to the grid, meaning that about 30 percent of the energy consumed up a ramp is regenerated going back down. Atlas Copco | Kenworth Truck Co. rolls out its new T880 vocational truck. The unit features a panoramic windshield for enhanced visibility, quiet cab with triple-sealed doors, a five-piece hood for easier and faster repairs, air-assisted hydraulic clutch, complex reflector headlamps, and new lightweight, factory-installed lift axles. Intended for a variety of uses, including heavy haul, the truck comes standard with a 12.9-liter Paccar MX-13 engine that has high-end ratings of 500 horsepower and 1,850 foot-pounds of torque. A Cummins ISX15 engine, with 600 horsepower and 2,050 foot-pounds of torque, is optional. Kenworth Truck Co. | Tracking operator fatigue Caterpillar Global Mining entered an alliance agreement with Canberra, Australia-based Seeing Machines Limited to deliver and support operator fatigue monitoring technology. Developed by the Australian company, the monitoring systems use patented eye and head tracking technology to detect operator fatigue and distraction, as well as to alert the mine controller and the machine operator. The alliance agreement also supports collaboration in future product development. The Driver Safety System, a commercial system for mining trucks, is working on more than 20 mine sites and 1,500 vehicles. Caterpillar Global Mining | Wheeled jaw crusher Irock Crushers introduces the Wheeled Jaw Crusher-2644 for use as a primary crusher. Powered by a 350-horsepower Caterpillar C-9 Acert Tier 3 engine, the unit can produce up to 370 tons per hour. With a capacity of 10.5 cubic yards, the hopper was designed significantly larger than similarly sized crushers. The crusher is equipped with a 48-inch by 36-foot discharge belt that features a fixed discharge height of 11 feet — said to be the highest stockpiling height in the industry — and can easily be paired with screening units. A hydraulic adjusting chamber allows operators to adjust crushing size from a 2-inch minimum closed-side setting to a 6-inch maximum side setting. The machine includes a 24-inch grizzly bypass conveyor, as well as a 40-inch by 14-foot feeder with a 5-foot grizzly bar section to ensure proper classification of material.
