CHCNAV MCNAV TX73 – 3D Excavator Control System

The CHCNAV MCNAV TX73 is a powerful 3D excavator control system that combines precise GNSS positioning, robust IMU sensors, and real-time 3D guidance. The TX73 accurately determines the position of the bucket tip and displays the planned surface directly in the cabin, allowing excavation work to be performed to the target depth without continuous traditional measurement.

Excavate precisely – exactly according to the plan

With the TX73, the operator sees the bucket's position and the planned surface in real-time. 3D guidance reduces excessive excavation, post-measurements, and rework, and speeds up work, especially on demanding sites.

The system is suitable for trenches, foundation excavation, slope construction, and road and infrastructure projects, for example.

Real-time 3D guidance on site

The TX73 displays the design model and bucket position in real-time on the cabin screen. The operator can monitor excavation depth, height, and slope directly during operation.

The 3D CAD engine enables clear visualization of design data, allowing work to be done directly based on the digital model.

Precise positioning for demanding excavation work

The TX73's precise GNSS positioning and IMU sensors determine the bucket tip's position in various working attitudes. The system's stated positioning accuracy is at best 1 cm horizontally and 1.5 cm vertically.

Precise positioning reduces over-excavation and unnecessary material movement, and helps achieve the planned surface already during the first pass.

CAD data directly in the cabin

In the TX73's 3D view, plans can be brought directly to site use. The operator sees the planned surface and working area without each work phase requiring a separate marking on the ground.

The solution is particularly suitable for model-based infrastructure, road, foundation, and earthmoving projects.

Compatible with various attachment configurations

The TX73 can be integrated into various excavators and attachment configurations. The system also supports tilt-rotator configurations and, for example, Engcon and Steelwrist tilt-rotators.

This allows the same machine control solution to be used versatilely in various excavation and finishing tasks.

Designed for demanding site conditions

The TX73 components are designed to withstand the demanding conditions of a worksite. The tilt sensor is IP69K-protected, and the GNSS antennas are IP68-protected. The 10.1-inch Android display is IP65-rated.

OTA updates and the MCSite cloud service enable system updates, data transfer, and remote support even during worksite operations.

Suitable for versatile earthmoving

The TX73 is suitable for example:

• trench excavation
• foundation excavation
• road and infrastructure construction
• slope and embankment construction
• pipe and network installations
• site elevation and slope control
• precise material exchange
• model-based earthmoving
• finishing excavation
• site 3D guidance
