Product Features and benefits:
Adapts to Operator Skill Level
A fully integrated grade assist ensures seamless adaptation to the operator’s skill level, automatically tracing the target surface to minimize over-digging. The built-in facing angle compass guarantees precise alignment with the target surface.
Automatic Stop Control
To prevent potential damage during boom or bucket operation, the excavator incorporates an auto-stop control mechanism. This feature halts the machine when the bucket edge reaches the design surface, enhancing operational safety.
Precision with Minimum Distance Control
Integrated Machine Control (IMC) facilitates bucket control by automatically selecting the point closest to the target surface. This minimizes operator input, leading to higher accuracy and increased confidence in grading tasks.
Tailored Precision for Utility Applications
For utility-focused tasks demanding unparalleled precision, the excavator allows operators to input structure details and invert elevations of pipe runs. It then automatically calculates the fall of the pipe, ensuring critical precision.
Environmentally Friendly Powerhouse
Equipped with IMC 1.0, excavators feature a Tier 4 Final certified Komatsu SAA6D107E-3 engine. This engine combines environmental friendliness with robust power, incorporating an integrated diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger, and a selective catalytic reduction system.
Real-Time Position Feedback
Utilizing stroke sensing hydraulic cylinders, the excavator provides real-time position feedback displayed instantly to the operator. This represents an improvement over conventional aftermarket machine guidance systems, offering tilt sensors that require stabilization time.
Stability in Action
A substantial counterweight and robust undercarriage components contribute to the excavator’s outstanding stability, ensuring reliable performance even in challenging operational conditions.
