Komatsu D155AXi-8 Crawler Dozer

March 31, 2015
Komatsu D155AXi-8 is an intelligent machine control dozer

The D155AXi-8 is another of the company’s intelligent machine control dozers that allows automated operation. It senses and controls blade load, optimizes the start of the cut, and minimizes track slip.

The 354-horsepower dozer is certified Tier 4-Final with a Komatsu SAA6D140E-7 engine that uses DPF and SCR. An electronically controlled, automatic gearshift transmission and lock up torque converter sets the optimal gear range based on job site conditions and load. It locks up the torque converter to transfer engine power directly to the transmission, which eliminates horsepower loss and cuts fuel consumption.

The pressurized cab allows less noise and dust inside than the previous model. Cab damper mounts isolate the cab from the machine frame, which softens shocks and vibrations.
