Product Features and benefits:
Integrative Grade Assist: Tailored to the operator’s experience level, the excavator features fully integrated grade assist functionality. This system automatically traces the target surface, minimizing the risk of over-digging. The built-in facing angle compass ensures precise alignment with the target surface.
Auto Stop Control: Enhancing operational safety, the excavator employs an auto stop control mechanism. This feature halts machine operation when the bucket edge reaches the designated surface, mitigating the potential for damage during boom or bucket actions.
Minimum Distance Control: IMC incorporates a minimum distance control strategy, automatically selecting the closest point to the target surface. This minimizes operator input, ensuring higher accuracy and boosting grading confidence.
Precision for Utility Applications: Catering to utility applications requiring utmost precision, the excavator allows operators to input structure details, invert elevations of pipe runs, and automatically calculates the fall of the pipe.
Powerful, Advanced Engine: Promoting environmental friendliness without compromising power, excavators with IMC 1.0 are equipped with a Tier 4 Final certified Komatsu SAA6D107E-3 engine. This engine boasts an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger, and a selective catalytic reduction system.
Stroke Sensing Hydraulic Cylinder: Real-time position information is provided to the operator through stroke sensing hydraulic cylinders. This improvement over conventional aftermarket machine guidance systems with tilt sensors ensures immediate and stabilized feedback.
Robust Undercarriage: The excavator boasts a robust undercarriage featuring a large counterweight and durable components, ensuring exceptional stability during operations.
Experience adaptability, precision, and reliability with our excavators designed to meet the diverse demands of operators across different experience levels.
