| Trimble GCS900 Grade Control System |
|
One of the most revolutionary changes in the way earthworks are performed has been the adoption of 3D systems, originally introduced by Trimble in 1995. The Trimble GCS900 Grade Control System represents the next-generation 3D system from the company that invented 3D grade control.
The Trimble GCS900 Grade Control System is a cutting-edge earthmoving grade control system that puts design surfaces, grades and alignments inside the cab. The system uses GPS, GPS and laser, or construction total station technology to accurately position the blade or bucket in real time, significantly reducing material overages and dramatically improving the contractor’s productivity and profitability.
The Trimble GCS900 is extremely flexible and can be used on excavators, dozers, motor graders and scrapers. You may purchase the GSC900 outright or as an upgrade from a GCS600 Grade Control System. And with its CAN-based design, the GCS900 can be easily moved from machine to machine, as needed.
The Trimble GCS900 Grade Control System is an automatic control system that puts design surfaces, grades and alignments inside the cab. The system uses the MS980 smart antenna, a fully integrated GPS receiver and antenna, mounted to each end of the machine blade. The system can be operated in a completely stakeless environment to grade to an accuracy of 20-30 millimeters (0.1 foot).

| Trimble GCS900 with Laser Augmentation |
|
The Trimble GCS900 with laser augmentation is a full 3D control system that puts the site plan, including the design surfaces, grades and alignments, all inside the cab. Laser augmentation provides exceptional blade control and increases accuracy to 3-6 millimeters (0.01 to 0.02 feet). The high accuracy gained by using GCS900 makes the system ideal for a wide range of earthmoving applications.
Using Trimble’s unique dual GPS antenna configuration, the exact position, cross slope, and heading of the blade is measured. The installed SR300 Laser Receiver then 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 grade laser.
The onboard CB430 control box uses this data and matches it to the design elevations to compute cut or fill to grade. The cut/fill data is also passed to the GCS900 lightbars, providing additional visual guidance to the operator for up/down to grade and right/left to a defined alignment. This cut/fill data is also used to drive the valves for automatic blade control.
With the automatic blade control option, the GCS900 system is connected to the machine hydraulics. Using 3D GPS position, cross-slope and design information, the blade is automatically moved to the exact elevation and cross slope. The result is significant improvements in both productivity and accuracy. If large cuts are required, the operator can instantly offset the design surface so smaller amounts are cut on each pass.
How does it work? Laser augmentation requires a transmitter, which is a standard rotating laser typically set up on a tripod. The transmitter defines itself as the benchmark base – thus eliminating the need to place it on a known design-plan mark. The set-up for a flat laser plan is that simple.
To optimize the laser-augmentation system for hilly sites, a sloping laser plane needs to be set by tilting the tripod-mounted laser transmitter to properly orient it and to benchmark the system.
Trimble grade lasers include both a grade match mode and automatic axis alignment to make setup for single and dual slope grade work easy.

| Trimble CCS900 Compaction Control System |
|
As the first satellite-based compaction positioning solution, the Trimble CCS900 Compaction Control System offers contractors the unique ability to compact surface material to a target density and check the finished grade accuracy in the same process. Using the Power GCS900 v.10.7 software combine with powerful Trimble satellite-based positioning sensors, the CCS900 extends the Trimble 3D grade control family to include soil and sub-surface material compaction for tandem rollers and single smooth-drum and padfoot rollers. The Trimble Compaction Control System provides continuous compaction control for contractors that require advanced compaction measurement capability, display and mapping of compaction measurements in real time, and on-machine documentation of compaction results. |

| Trimble GCS900 UTS |
|
The Trimble GCS900 UTS is an ideal grade control solution for contractors who need the flexibility to move from site to site frequently, work in confined spaces, or perform high-precision grading with their dozer or motorgrader. A Trimble SPS930 or SPS730 Universal Total Station allows contractors who operate independently or frequently move between projects to move both the dozer 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 wooded areas, or on job sites with numerous overhead obstructions such as overpasses, the total station offers a 3D grading solution.
Using the Trimble SPS930 or SPS730 Universal Total Station, the exact position, 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 then is displayed on the Trimble CB430 screen in the necessary format, whether in plan, profile, cross-section view, or text. 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. In addition to support for a motorgrader system, the GCS900 UTS system can also be used on a dozer, where it can be operated in either indicate or automatic mode. |
