The CHCNAV EasyNAV EMG100 is an advanced 3D machine control system that brings precision and efficiency to the excavation process. By integrating high-precision GNSS positioning with rugged motion sensors, the EMG100 allows excavator operators to "see" the bucket’s teeth in relation to the digital 3D design profile in real-time. This digital transformation eliminates the guesswork, reduces over-excavation, and minimizes the need for ground personnel to perform manual grade checks.

High-Precision 3D Guidance

At the heart of the EMG100 are two high-performance GNSS antennas and a series of robust 9-axis MEMS sensors installed on the boom, arm, and bucket. The system calculates the exact 3D position and heading of the excavator, as well as the real-time attitude of the working tools. This data is processed instantly and displayed on a 10.1-inch industrial-grade touchscreen in the cab. Operators can follow the on-screen cut/fill indicators to reach the target grade with centimeter-level accuracy, regardless of whether the bucket is submerged or out of direct sight.

Digital Construction Workflow

The EMG100 supports a fully digital workflow by allowing users to import complex design files such as LandXML and DXF directly into the system. This means project designs—ranging from simple slopes to complex foundations and trenching—can be executed exactly as planned. The "EasyNAV" philosophy ensures that the software interface is intuitive for operators of all skill levels, featuring a 3D visualization that reduces the learning curve and boosts confidence on the job site.

Key Features and Benefits

• Real-Time Depth Control: Prevents over-digging, saving time and expensive backfill material.
• Enhanced Site Safety: Reduces the need for surveyors and grade checkers to be near moving heavy machinery.
• Rugged Reliability: All components, including sensors and antennas, are IP67 rated to withstand the vibrations, dust, and moisture typical of construction sites.
• All-Day Productivity: High-brightness display ensures clear visibility even in direct sunlight, enabling 24/7 operation if required.
• Versatile Compatibility: Can be easily retrofitted onto various excavator makes and models, from mini-excavators to large crawler units.

Typical Applications

• Infrastructure Projects: Precise grading for road construction, embankments, and slopes.
• Trenching & Utilities: Accurate depth and slope control for water, gas, and sewer line installations.
• Foundation Excavation: High-precision digging for building footings and basements.
• Underwater Works: Blind excavation in dredging or harbor construction where the bucket is not visible.
