I DA U N I V E R S A L J u l y -Au g u s t 2 0 1 6 23 NUTS AND BOLTS NEWS Less than a week out from a media event focusing on "the jobsite of the future" at its North American customer center in Catersville, Georgia, Komatsu unveiled its latest semi-automatic dozer. e new D39PXi-24 replaces the D39PXi-23, which was intro- duced in 2014. It is the second- smallest dozer in Komatsu's intelligent Machine Control (iMC) product lineup, which includes fi ve other dozers and the PC210LCi-10 excavator. Along with updating the machine's engine from a Tier 4 Interim to a Tier 4 Final model, Komatsu has also introduced a few new features to the iMC lineup with the D39PXi-24. Powered by a 3.26-liter Komatsu SAA4D95E-7 engine, producing 105 horsepower, the dozer, like the rest of the iMC dozer lineup, is set apart by built-in machine control, which allows the machine to be placed in automatic mode from rough dozing all the way through to fi nish grading. iMC allows the dozer to sense and control blade load, thanks to a pairing of stroke-sensing hydraulic cylinders and an Inertial Measuring Unit. When auto mode is engaged, the system automatically starts the cut and lowers the blade to the correct grade. e blade is raised once the system senses that the load has increased to the maximum. Komatsu's New D39PXi-24 Semi-auto Dozer Brings Reverse Grading Mode to iMC Lineup Komatsu says iMC provides an eight percent boost in effi ciency, compared to typical a ermarket machine control systems. And since the system is wireless and mounts no compo- nents to the machine's blade, there's no need to worry over any damage to the hardware. Beyond the typical iMC tech, the D39PXi-24 also brings a new standard automatic reverse grading mode. is feature, added a er customer requests, enables auto blade control while reversing. e dozer has also been improved with a new "Triple Labyrinth" housing design, which off ers more protection for the fi nal drive fl oating seals, and a new water- cooled variable fl ow turbocharger. On this updated model, Komatsu has also included auto-idle shutdown. e iMC dozer lineup now consists of the D37PXi-23, the D39PXi-24, the D65PXi-18 and D155AXi-8. Komatsu plans to introduce two more iMC dozers in the coming weeks. ● www.equipmentworld.com, 5/16 D155AXi-8 D65PXi-18 Nuts & Bolts continued on page 25
