Komatsu introduces the new intelligent Machine Control D155AXi-8 crawler dozer with radio control option

Komatsu America Corp. has introduced the new D155AXi-8 Radio Control dozer, Komatsu’s first radio controlled machine with intelligent Machine Control technology. It is the latest addition to the next generation of machine control and dozer technology.

“The D155AXi-8 Radio Control dozer is ideal for applications where customers may want to remove the operator from the machine and still maintain high levels of efficiency and productivity,” said Sebastian Witkowski, product manager, Komatsu America Corp. “This dozer meets customer demands in those applications, while utilizing Komatsu’s proven, automated, rough-cut-to-finish-grade technology,” Witkowski said.

Innovative, integrated, intelligent

For many operators, the ability to feel machine response to blade load is an important factor in effective dozing. This is naturally difficult for a radio control application where the operator is separated from the machine. The D155AXi-8 RC dozer is unique among radio control dozers thanks to the enhanced “intelligence” that automates operation from heavy dozing to fine grading to efficiently doze material. The D155AXi-8 RC has the ability to sense and control blade load, optimize the start of the cut, and minimize track slip.

Powered by a 354-hp Komatsu SAA6D140E-7, Tier 4 Final emissions certified engine, the D155AXi-8 emits 80 percent less nitrogen oxides (NOx) than its Tier 4 Interim predecessor. The variable geometry, turbocharged and after-cooled, 15.24 litre diesel engine features Komatsu Diesel Particulate Filter (KDPF) and Selective Catalytic Reduction (SCR) systems and achieves fluid-neutral fuel economy.

Time-saving productivity

An automatic gearshift transmission and lock-up torque converter team up to select the optimal gear range, depending on jobsite conditions and load. They are designed to provide maximum operation efficiency. The electronically controlled transmission locks up the torque converter to transfer engine power directly to the transmission, eliminating horsepower loss and cutting fuel consumption by up to 10 percent.

The patented SIGMADOZER blade, designed to dig and roll up more soil at the blade’s centre, holds more material, reduces digging resistance and dozes up to 15 percent more soil while using less power, compared to a typical semi-u blade.

The D155AXi-8 radio control dozer, whether rented, leased or purchased, is covered by the Komatsu CARE program for the first three years or 2,000 hours, whichever comes first. Komatsu CARE includes scheduled factory maintenance, a 50-point inspection at each service, and two complimentary Komatsu Diesel Particulate Filter exchanges and DEF tank flushes in the first five years.
