Product Features and benefits:
Adaptable to Operator Expertise
Designed to accommodate varying operator experience levels, the excavator features a fully integrated grade assist system that automatically traces the target surface, minimizing the risk of over-digging. The built-in facing angle compass ensures precise alignment with the target surface, enhancing operational accuracy.
Auto Stop Control
The machine is equipped with auto stop control, a safety feature designed to prevent potential damage during boom or bucket operation. When the bucket edge reaches the design surface, the excavator automatically halts, contributing to operational safety.
Minimum Distance Control
Integrated Machine Control (IMC) incorporates minimum distance control, automatically selecting the closest point to the target surface. This minimizes operator input while significantly enhancing accuracy and confidence in grading operations.
Precision for Utility Applications
For utility applications demanding precision, the excavator enables operators to input structure details, invert elevations of pipe runs, and automatically calculates the fall of the pipe. This feature ensures utmost accuracy in utility-related tasks.
Powerful and Environmentally Friendly Engine
Equipped with the advanced Komatsu SAA6D107E-3 engine, excavators with IMC 1.0 achieve Tier 4 Final certification. This engine integrates a diesel particulate filter, hydraulically actuated Komatsu variable geometry turbocharger, and a selective catalytic reduction system, providing both power and environmental sustainability.
Real-time Positioning with Hydraulic Cylinder
Utilizing stroke sensing hydraulic cylinders, the excavator provides real-time position data immediately displayed to the operator. This represents an improvement over conventional aftermarket machine guidance systems with tilt sensors, offering stability without the need for stabilization time.
Robust Undercarriage for Stability
A robust undercarriage, featuring a large counterweight and sturdy components, ensures outstanding stability for the excavator. This design enhances the machine’s performance and reliability in various working conditions.
