Intelligent Automated Blade Positioning

What Is Trimble Earthworks for Dozers?

Trimble Earthworks for Dozers is a construction technology solution that automates blade positioning and grading accuracy through integrated GNSS technology and intuitive Android-based software. It is part of the broader Trimble Earthworks construction platform used globally to optimise earthworks construction and machine productivity.

This grade control system continuously compares the dozer blade position to the digital design surface and provides real-time cut and fill information in the cab. Operators can follow design alignments automatically, improving situational awareness while increasing precision and efficiency. As a connected machine control system, Earthworks for Dozers reduces dependency on survey staking and manual grade checks while improving overall site coordination.

Trimble® Earthworks for Dozers Grade Control Platform is designed to help you do more in less time. Reengineered from the ground up, our innovative, next generation grade control platform features intuitive, easy-to-learn software that runs on an Android operating system.

State-of-the-art software and hardware give operators of all skill levels the ability to work faster and more productively than ever before.

Intuitive Software

The Trimble Earthworks grade control app runs on the new 10-inch (25.7 cm) Trimble TD520 touch-screen Android display.
The software was created in collaboration with construction equipment operators around the world, so the interface is optimized for ease-of-use and productivity.

Horizontal Steering Control

Automatically control the machine to follow any horizontal alignment from the 3D model. This allows the operator to focus on grade, machine productivity and safety rather than worrying about steering, for increased situational awareness, better accuracy and improved productivity with decreased overlap and fewer passes.

Cab-mounted Portability

Trimble Earthworks for Dozers mounts dual GNSS receivers on top of the cab to eliminate masts and cables traditionally located on the blade. The dual GNSS receivers are ideal for steep slope work and complex designs with tight tolerances.

Configuration Options

Configuration Options for Dozers

Trimble Earthworks for Dozers is available in both 2D and 3D configurations, each designed to suit different project types, site conditions and accuracy requirements. The table below outlines the available system configurations, their intended applications and a brief description of how each operates, making it straightforward to identify the right solution for your specific operational needs.

Product	Application	Configuration	Description
3D	Highway and railway construction Airport construction Concrete pours and slab placement Residential and commercial site construction	Single GNSS	Measures the position and slope of the blade and compares that to design data for fine grading on complex design surfaces
		Dual GNSS	Measures the exact position, cross slope and heading of the blade for fine grading on steep slopes and complex design surfaces
		Universal Total Station (UTS)	Total station based system for extreme accuracy for lift and layer control, material monitoring, or where GNSS is not the ideal solution because of overhead obstructions
2D	Road and highway projects Land reclamation projects Dam and reservoir construction New infrastructure projects	Cross-slope Only	Cross-slope control system to be used on motor graders for fine grading work for road maintenance, ditches and slope work
		Single Elevation Plus Cross-slope	Single control system uses a laser or sonic receiver to control the lift of the machine blade and the cross-slope for flat, slopework, and finished grading
		Dual Elevation	Dual control system that uses a laser receiver and a sonic tracer for higher accuracy lift control. Blade edge can be controlled independently or linked

Millimetre Accuracy at Scale

3D Grade Control for Dozers

3D grade control for dozers uses dual GNSS receivers mounted on the cab and digital 3D site models to automate blade control. The system calculates real-time cut and fill values and automatically adjusts the blade to match the design elevation.

This solution is ideal for large infrastructure projects, mining support, site development and road construction where precision and productivity are critical. With automatic blade control and horizontal steering functionality, operators can achieve millimetre-level accuracy with fewer passes.

Bulk Earthworks

Display design information and live cut/fill indications in the cab
Monitor avoidance zones with real-time information
Collect as-built data as the machine cuts to grade Keep tighter control over safety issues
See precisely where dirt is being moved on site

Grading

Determine the position of each tip of the blade and compare it to the design elevation to compute cut or fill to grade
Drive the valves for automatic blade control or view in-cab lightbars based on the cut or fill data
Control the machine’s automatic blade control settings in real-time
Adjust the machine’s response to differing material conditions
Optimize the machine’s performance for a particular grading task

Finished Grading

Achieve finished grade to millimetre accuracy with fewer passes
Place finished grade materials more accurately and in a shorter time period
Keep the material costs to a minimum and realize better profits

Millimetre Accuracy at Scale

2D Grade Control for Dozers

The 2D grade control system uses laser receivers, slope sensors and elevation references to guide blade movement. It is an ideal first investment for contractors new to machine control systems and looking to improve grading consistency. 2D grade control provides accurate elevation and slope guidance, helping operators reach grade quickly while reducing rework and material waste. The system can be easily upgraded to 3D grade control as project complexity increases.

Grading

Use a single laser and laser receiver to measure the lift and tilt of the blade
Add another laser receiver or a slope sensor to measure the slope of the blade
Get elevation and slope guidance to get to grade quickly and accurately
Easily upgrade to a 3D grade control system
