Powerful
Set by default, the D155AX-8 has a highly efficient transmission that automatically matches the best gear mode in all dozing operations and includes a travel speed preset function to reduce work time and fatigue for the operator. With Komatsu’s ECMV (Electronic Controlled Modulation Valves) gear changes are smoothly timed to always keep the power transfer at maximum efficiency.

First-Class Comfort
The cab on the D155AX-8 is quiet and comfortable, providing an ideal environment to concentrate on the job. Its hexagonal design and large tinted glass windows offer excellent panoramic visibility. The high capacity and fully automatic climate control system pressurises the cab to keep dust out. A high quality sound-absorbent lining covers the interior to minimise noise levels for the operator.

Safety First
The redesigned ROPS/FOPS integrated cab and the well-located operator seat give optimal blade visibility to the left and right and make both dozing and grading easy, safe and fast. The special shape of the fuel tank improves view of the ripper point and the machine’s rear to enhance safety and ripping efficiency.

Environmentally Friendly
The Komatsu EU Stage V engine is productive, dependable and efficient. With ultra-low emissions it reduces environmental impact while delivering strong performance to help lower operating costs.

Easy Maintenance

• Self-diagnostic monitor – The multifunction monitor panel displays running time, engine revs, fuel level and coolant temperature in real time. It provides maintenance and service information (for example when oil filters need replacing) and supplies detailed information for service personnel without external service tools.

KOMTRAX and Komatsu CARE
KOMTRAX is Komatsu’s wireless monitoring system that enables tracking, performance monitoring and status updates for machines. Komatsu CARE is a maintenance program included with new machines covering factory-scheduled maintenance performed with genuine parts by trained technicians.

Environmental commitment
Komatsu has committed to halving CO2 emissions from 2010 levels by 2030 and aims for net zero CO2 emissions from production activities by 2050, promoting related technologies across its supply chain.
