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.

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.

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.

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.

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.

• 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

• 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

• 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

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.

• 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
