Productivity and Economy

This equipment offers an outstanding productivity and fuel economy due to its new SIGMADOZER blade, reducing digging resistance and increasing material rolling up effect in order to reduce pushing resistance and increase load capacity. It also has an automatic transmission with lockup torque converter, increasing speed and power in order to improve fuel consumption and productivity.

The D155AX-6 bulldozer has a turbocharged aftercooled SAA6D140E-5 diesel engine with a 264 [kW] 354 [hp] net power, delivering excellent productivity. It also is EPA Tier 3 and UE Stage 3A certified.

Features

Wide and comfortable cab

New cab with ROPS integrated for a wider and quiet environment for the operator, a comfortable movement due to the new cab mount, an excellent visibility due to the pillar-less ROPS, and adjustable armrests with suspension. An air conditioning system with greater capacity and pressurized cab can be optionally installed. It also has a wide 7” LCD TFT multi-colored user-friendly monitor.

Palm command control system (PCCS)

The new Palm command control system (PCCS) allows a fully operator-controlled operational environment. Its travel control joystick provides a comfortable posture and great control for the operator, reducing the fatigue. Gearshifting is performed easily through finger-pressed switches. The second joystick, for blade controlling, uses a PPC (Proportional pressure control) valve, which combined with its highly reliable hydraulic system, results in a clean and precise control.

Hydrostatic Steering System (HSS)

The hydrostatic steering system is powered by an independent hydraulic pump with engine power transmitted to both tracks without power interruption on the inside track. When the machine turns, the outside track moves faster and the inside track slower to achieve smooth and powerful turns. Counter-rotation can be performed with a lower turning radius, which makes maneuvering easier. Smooth turns reduces the machine’s vibrations and increases operator comfort.

The shock-free steering controller reduces the machine’s vibrations and the operator’s fatigue. The hydrostatic steering system reduces greatly the road damage produced by the tracks.

Ecology & Economy - Technology 3

Komatsu, following its Ecology and Economy policy, continues to develop engines with high performance low-emission technologies, complying with the most rigorous environmental standards, such as the new EU Stage 3A and EPA Tier III emission regulations.

With this technology, Komatsu introduces its new Ecot3 engines with total electronic control system; fuel injection (Heavy-duty and high-pressure common rail); exhaust gas recirculation (EGR); air to air aftercooler and a new combustion chamber design; and NOx, PM and fuel consumption reducing systems.
