Powerful

The Komatsu D155A-6 stands out in both ripping and dozing operations, thanks to its superior engine performance. Designed for optimal productivity and economical efficiency, the main components of this dozer work in harmony within a total control system. This system automatically adjusts fan rotation based on coolant and hydraulic oil temperatures, resulting in reduced fuel consumption while enhancing productivity.

First class comfort

High rigidity and superb sealing performance sharply reduce noise and vibration for the operator and help prevent dust from entering the cab. The result is relaxed operation in a comfortable environment. The D155A-6’s cab mount uses a cab damper with a long stroke, providing excellent shock and vibration absorption capacity. The bi-level control function keeps the operator’s head and feet cool and warm respectively, while the improved airflow function ensures the cab remains comfortable throughout the year.

Blade

The frontal design concept, adopted for digging and rolling up at the center of the blade, increases soil holding capacity while simultaneously reducing sideward spillage. Reduced digging resistance produces a smoother flow of earth, enabling the dozing of larger quantities of soil with less power. In addition, adopting a blade linkage system keeps the blade closer to the tractor for improved visibility, enhanced digging force, and reduced lateral sway.

Maintenance

The opening area is significantly expanded when the gull-wing engine side covers are opened, making engine maintenance and filter replacement more accessible. These covers have been upgraded to a durable one-piece structure with a bolt-on catch, enhancing their longevity. Additionally, the monocoque track frame features a substantial cross-section and employs pivot shaft mounting, which contributes to greater reliability.
