This versatile dozer excels in heavy site preparation and precise fine work. Powered by an environmentally friendly EPA Tier 4 Final certified engine, it provides operators with a quiet, comfortable cab offering unparalleled blade visibility. Engineered for quick and accurate job completion, it features outstanding blade response, fast work equipment speed, an additional “fast-blade mode” boosting blade speed for high-speed grading, and impressive maneuverability with full power to both tracks during turns or counter-rotation steering.
- Efficiently train new operators
- Accelerate from mass excavation to finished grading faster than before
- Seamlessly integrate 3D design data into your machines
- Empower operators for efficient performance, pass after pass
Product Features and benefits:
- Learns as It Works:
- Proactive dozing control enables less experienced operators to automatically cut or strip from existing terrain.
- The dozer measures the terrain it tracks over and utilizes this data to plan the next pass.
- Productivity improvement of up to 60% compared to the previous generation.
- Automatic Spreading of Fill Material:
- Lift layer control allows operators to spread fill material from existing terrain with a simple button press.
- The dozer measures the terrain and plans the next pass, achieving up to double the production and consistent layers for compaction quality.
- Tilt Steering Control for Rough Dozing:
- Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing.
- Reduces operator steering input by up to 80%.
- Quick Surface Creation:
- Operators can create a temporary design surface with the press of a button, allowing for automated stripping or spreading while waiting for the finish grade model.
- Closing the Operator Skill Gap:
- Machine logic enables continuous learning of the terrain, making calculated decisions for the next pass.
- Helps reduce the skill gap between new and experienced operators.
- Advanced Machine Control:
- In select situations like auto stripping, rough dozing, spreading, and advanced finish grading, operators can opt for nearly 100% machine control.
- Automatic control without the need for a 3D model.
- Machine Learning from Operator Input:
- Automatic functions allow the dozer to learn from the operator’s blade input, providing adaptability, ease of operation, and reduced reliance on operator input.
- Outstanding Blade Response for Finish Grading:
- IMC enables the dozer to anticipate grade transitions and adjust the blade angle accordingly, delivering unparalleled grading performance.
These features collectively make Komatsu’s IMC 2.0 an advanced and adaptive system, enhancing dozing efficiency, reducing operator skill gaps, and improving overall productivity in various dozing applications.
