The affordable and practical 3D machine guidance choice.
CHCNAV TX73 3D excavator system is packed with features that help operators work smarter, faster and more accurately on every project!
Scales with Your Business -Start with the TX73 Basic and enable full 3D design capabilities only when needed. No additional hardware or installation required.
On-Site Training & Local Support - Comprehensive on-site training and on-going remote support from our local NZ team to ensure you get the most out of your gear.
Simple Operation - Designed for operators of all experience levels, it is simple and intuitive to use. Learn to operate the system efficiently in just 30 minutes.
High Precision, Zero Lag - Centimetre accuracy with real-time cut/fill feedback, for precise excavations with fewer errors and less rework.
Universally Compatible - Fully compatible with a diverse range of excavators and attachments. Upload design file formats and connect to base stations from all major GPS brands.
Seamless Connectivity - Seamless connection to all GNSS RTK networks and all major brands of base stations ensuring a consistent workflow and minimizing downtime.
Cloud Integration - Improve coordination between site and office by remotely accessing your fleet to upload 3d models, manage design revisions and export as-built survey data.
Purchase, Lease or Hire - Not ready to purchase upfront? We offer lease to own, monthly installments, or hire arrangements for all systems.
Built to last with tough components and rugged tablet.
The system is designed with durable components, including the MC300 receiver, an IP69K-rated IMU sensor, dual IP68 GNSS antennas and a quick-release mechanism for easy tablet removal, to ensure durability in harsh environments.
Two TX73 excavator systems to choose from.
The TX73 3D excavator systems offers two variants - Basic and Advanced. Both include the same durable hardware including tilt sensors and GPS antennas, the same Android based 10.1 inch rugged tablet and seamless cloud data syncing between field and office, ensuring operators are always using the latest approved earthworks design revision without the need for USB uploads.
TX73 Advanced
This system has all the features including the ability to upload digital 3D models and CAD e.g. Full highway, civil engineering or large-scale foundation blueprints directly into the display. It is compatible with heavy-duty attachments like an Engcon or Steelwrist tiltrotator, whereby the Advanced system computes the exact angles, swing booms and complex articulation for the bucket.
TX73 Basic
This system limits the Operator primarily to what can be designed in-cab, such as creating flat planes, foundation designs or simple slopes by dropping points. It is also compatible with tilt hitches and tiltrotators. Apart from this one main difference, the TX73 Basic has the same functionality as the TX73 Advanced system.
Upgrade On Demand
The TX73 Basic system is designed to enable Contractors to step into 3D machine control for less upfront cost. The beauty of this set up is that because both systems use the same foundational hardware, the Basic system can be upgraded to the full Advanced functionality via a simple license code. This can be a permanent upgrade or a month by month upgrade as your project requires.
