10 AGGREGATES MANAGER / September 2016 by Therese Dunphy | Editor-in-Chief | tdunphy@randallreilly.com ROLLOUTS Your complete guide to new and updated equipment and supplies in the aggregates industry. Industry's biggest artic hauler Volvo's A60H articulated hauler is designed for heavy hauling in severe off-road applications. The 60-ton truck is powered by a 16-liter engine and delivers 663-horsepower and 2,360 foot- pounds of torque. The truck is based on the same design and lay- out as the smaller trucks in Volvo's lineup, but offers a 44.5-cubic- yard capacity. The A60H features intelligent systems including Ma- tris, CareTrack, and an onboard weighing system. With a matched drivetrain, automatic drive combination — including 100-percent differential locks, all-terrain bogie, hydro-mechanical steering, and active suspension — the truck also focuses on operator comfort to address all aspects influencing productivity. Volvo Construction Equipment | www.volvoce.com Radio-controlled dozer Komatsu America Corp. rolls out the D155AXi-8 Radio Control dozer, its first radio-controlled machine with intelligent Machine Control tech- nology. Suited to applications where an opera- tor may want to be removed from the cab, the "intelligence" features allow the machine to maintain high levels of efficiency and produc- tivity in operations ranging from heavy dozing to fine grading. Powered by a 354-horsepower Komatsu SAA6D140E-7, Tier 4 Final engine, the machine emits 80 percent less nitrogen oxides than its Tier 4 Interim predecessor. An automatic gearshift transmission and lock-up torque converter select the optimal gear range for the site conditions and load, eliminating horsepower loss and cutting fuel consumption by up to 10 percent. A patented Sigmadozer blade, designed to dig and roll up more soil at the blade's center, is said to hold more material, reduce digging resistance, and doze up to 15 percent more soil while using less power than a typical semi-U blade. Komatsu America Corp. | www.komatsuamerica.com Jaw update addresses fines Sandvik adds a new model to its jaw crusher lineup, the QJ341+. The portable crusher incorporates a double-deck pre-screen as standard. Said to provide high amplitude for improved separation, the unit can remove a large amount of fines to improve effi- ciency and productivity, while reducing wear. A new telescopic natural fines conveyor, with a discharge height of 10 feet, 3 inches, deals with the increased flow of pre-screened material. The dirt chute fea- tures a steeper angle for faster transfer, as well as improved handling of sticky material. Its three positions allow material to pass the pre-screen grizzly to be diverted onto either the main conveyor or natural fines conveyor, with the middle position able to feed either the main conveyor or natural fines conveyor. An improved self-locking hopper allows for quick setup from the ground level. Operators can choose between a Cat and Volvo engine. Sandvik Construction | www.construction.sandvik.com
