The Komatsu D155A-6 is a 41.7-tonne mining crawler dozer powered by a 360 HP engine. Its 9.4 m³ blade provides substantial material-moving capacity, while two ripper configurations give operators different approaches to breaking. The 3-shank multi-shank ripper reaches 900 mm, whereas the giant single-shank reaches 1,370 mm for deeper work. SIGMADOZER, Semi-U and Full-U blade configurations are available for different applications. Ground bearing pressure is 115.8 kPa, with 500 mm of ground clearance for rough mining surfaces. A 625-litre fuel tank supports full-shift operation. The D155A-6 is the smallest of Komatsu's listed mining crawler dozers and sits below the D275A-5R, D375A-6 and D475A-5E0. Quarry and opencast operations are suitable applications. Pricing is available on request from mining dozer dealers. A mining contractor moving beyond construction-class equipment can consider this dozer machine when greater pushing and ripping capacity becomes necessary. The two ripper configurations allow buyers to match the setup to the ground. Its operating weight keeps it below the larger Komatsu mining machines. For operators entering mining-class dozer ownership, the D155A-6 provides a practical starting point before moving into higher-capacity equipment.

Key Highlights of Komatsu D155A-6

Features of Komatsu D155A-6

Engine and Output

  • Turbocharged SAA6D140E-5 diesel delivering approximately 268 kW (360 HP) for heavy dozing.

  • Net power gives the bulldozer push force and material displacement on rough terrain.

  • Automatic transmission with lock-up torque converter raises speed and fuel efficiency.

Blade Volume and Cycle Time

  • SIGMADOZER blade is a high-capacity semi-U design of about 9.4 cubic metres that cuts digging resistance.

  • Blade height adjusts across a wide range, which sharpens grading precision in leveling and pushing.

  • Load capacity and dozing efficiency both benefit in construction, mining and excavation.

Undercarriage and Component Life

  • Operating weight of about 41,700 kg makes this a stable dozer platform on difficult surfaces.

  • Dust-proof track design with flat-face O-ring seals blocks contaminant ingress, which is what extends track life on a dozer machine.

  • Undercarriage materials and segmented sprockets are specified for severe environments.

Cab, Monitoring and Automation

  • Integrated ROPS/FOPS cab has adjustable suspension seating, good visibility and reduced noise.

  • Palm Command Control System with joystick and electronic blade control keeps operation ergonomic.

  • Large multi-colour LCD monitor and a customisable gearshift pattern cover real-time monitoring.

    Why Choose Komatsu D155A-6

    • The D155A-6 is the modern electronic generation of the platform BEML still builds in licensed form: automatic TORQFLOW transmission with a lockup torque converter, electronic engine control, and selectable power and economy working modes.
    • The lockup converter is the buying argument. In long pushes it locks driveline slip out entirely, so fuel that older D155-class machines lose as converter heat becomes drawbar pull instead. Over thousands of mining hours, that difference funds itself.
    • All that technology depends on Komatsu dealer diagnostics and genuine parts. It rewards disciplined, professional fleet operation and punishes casual maintenance in a way its mechanical ancestors never did.
    • Choose it for sustained production dozing and ripping in mining and large infrastructure, where fuel per bank cubic metre is measured and the dealer relationship is already in place.
