Komatsu’s D155AXi-8 Radio Control dozer is its first radio-controlled machine with intelligent Machine Control technology. Suited to applications where an operator may want to be removed from the cab, the ‘intelligence’ features allow the machine to maintain high levels of efficiency and productivity in operations ranging from heavy dozing to fine grading. It is powered by a 354-horsepower Komatsu SAA6D140E-7, Tier 4 Final engine. An automatic gearshift transmission and lock-up torque converter select the optimal gear range for 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.
