CHCNav MCNAV TX73 is designed for demanding construction sites. The system gives operators full control of depth, slope, and alignment using advanced GNSS RTK receivers and IMU sensors. With instant bucket-tip feedback and real-time surface comparison, jobs finish faster, cleaner, and with fewer grade checks.
The TX73’s powerful CAD-based 3D interface and color-coded maps let crews visualize progress directly in-cab. Operators can customize layouts, monitor cut/fill data, and switch effortlessly between 2D and 3D views. With broad attachment compatibility—including Engcon and Steelwrist tiltrotators—the TX73 adapts easily to complex projects. Its rugged hardware—featuring the MC300 receiver, IS300 IMU, and AT315 GNSS antennas—ensures reliability in harsh environments.
- High-Precision GNSS + IMU Integration The TX73 combines dual GNSS receivers with rugged IMU sensors to deliver centimeter-level accuracy, ensuring precise bucket-tip positioning in real time. Operators can dig directly to design grade without stakes, minimizing errors and rework.
- Real-Time Cut/Fill Feedback Live cut/fill data displayed on the control tablet helps operators maintain grade accuracy, reduce over-excavation, and complete trenching, slope, and foundation work more efficiently.
- CAD-Based 3D Visualization A powerful CAD engine supports detailed design files and provides 3D, top, and side views for superior situational awareness. Color-coded progress maps make it easy to monitor excavation status at a glance.
- Customizable Operator Interface The intuitive 10.1″ touchscreen interface allows users to tailor shortcuts and display settings to their preferences. Guided calibration and clear visuals help both new and experienced operators work confidently.
- Broad Machine and Attachment Compatibility The TX73 works seamlessly with standard excavators as well as Engcon and Steelwrist tiltrotators, triple and swivel booms, and offset arms. Quick recalibration supports bucket or attachment changes without extended downtime.
- Advanced Connectivity and Cloud Access The system connects easily to GNSS RTK networks and multiple radio protocols, while the MCSite (iSite) cloud platform enables remote troubleshooting, data synchronization, and over-the-air updates for continuous uptime.
- Rugged, Job-Ready Hardware Each component—from the MC300 receiver to the IS300 IMU sensor and AT315 antennas—is built for heavy-duty use with IP68–IP69K protection, shock resistance, and vibration tolerance to perform reliably in harsh site conditions.
