Product Details

With Dual GPS

The Trimble® GCS900 Grade Control System with dual GPS can be installed on motor graders for a wide range of earthmoving applications. The Trimble GCS900 on a motor graders with dual GPS is a full 3D control system that puts the site plan - design surfaces, grades and alignments - inside the cab.

The dual 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. GPS-based Grade Control Systems are ideal for larger site projects and long-term, multi-phase projects.

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 grader can be operated in either indicate or automatic mode.

GPS-based Grade Control Systems are ideal for larger site projects and long-term, multi-phase projects. Using the Trimble GCS900 with dual GPS on a motor grader allows contractors to significantly improve their productivity and profitability.

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 Trimble SPS930 or SPS730 Universal Total Station includes a total station, a license-free radio link and an active target mounted to the dozer blade. The total station uses active target technology to reliably lock onto and track the target. This unique feature eliminates false lock-ons, ensuring that the correct machine is being tracked. Additionally it has built-in "search intelligence" to quickly search for and find the target when lock is lost. The high up-date rate, low latency and synchronized angles and distance measurements capabilities make it perfect for dynamic applications.

The Trimble GCS900 on a motor grader with the Trimble SPS930 or SPS730 Universal Total Station is ideal for contractors who need the flexibility to move from site to site frequently, work in confined spaces, or require high-precision grading. The Total Station allows contractors who operate independently or frequently move between projects to move both the motor grader and the Trimble GCS900 Grade Control System from site to site quickly and easily. For jobs where GPS is not a viable technology, such as in urban canyons, heavily treed areas, or on job sites with numerous overhead obstructions such as overpasses, the total station offers a 3D grading solution.
