Trimble GCS900 on a Motor Grader with Dual GPS and Laser Augmentation
The Trimble® GCS900 Grade Control System with dual GPS and laser augmentation can be installed on motor graders for a wide range of earthmoving applications. The Trimble GCS900 on a motor grader with dual GPS and laser augmentation is a full 3D control system that puts the site plan - design surfaces, grades and alignments - inside the cab.
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 or the LL500 Laser Level. 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 Control Box 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. The GCS900 on a motor grader can be operated in either indicate or automatic mode.
Using the Trimble GCS900 with single GPS on a motor grader allows contractors to significantly improve their productivity and profitability.
