The Trimble® GCS900 Grade Control System with GPS and laser augmentation can be installed on dozers or motor graders for a wide range of earthmoving applications.

 

The Trimble SR300 Laser Receiver provides improved vertical accuracy and is ideal for GPS operations with tight tolerances. The Trimble SR300 features 360 degree receiving and works with a standard laser transmitter such as the Trimble GL700 series of grade lasers. And with intelligent rejection of invalid laser beams the SR300 is designed to work on jobsites where other lasers maybe present.

 

The dual GPS antenna configuration is unique to Trimble GPS-based Grade Control Systems. Using GPS, the exact position, very accurate cross slope, and heading of the blade is measured. This is especially advantageous for complex design surfaces such as super-elevation grading tasks.

 

The on-board computer uses this position information, and compares it to the design elevation to compute cut or fill to grade. This information displays on the Trimble CB430 screen- in plan, profile, cross-section view, or text. The cut/fill data is also used to drive the valves for automatic blade control.

 

Additionally, the cut/fill data is passed to the GCS900 lightbars, providing additional visual guidance to the operator for up/down to grade and right/left to a defined alignment.

 

Using the Trimble GCS900 with dual GPS and laser augmentation on a dozer allows contractors to significantly improve their productivity and profitability.
