Trimble® GCS900 Grade Control System for Dozers
The Trimble® GCS900 Grade Control System can be installed on dozers for a wide range of earthmoving applications. The Trimble GCS900 on a dozer 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.
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. The GCS900 on a dozer 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 dozer allows contractors to significantly improve their productivity and profitability.
The Trimble GCS900 Dozer System can run in either Indicate / Manual mode or fully automatic.
With the option of single or dual GPS antennas, you have even more options to meet your specific needs and budget:
- Single Antenna systems are recommended for dozers with fixed four-way blades and motor graders.
- Dual Antenna systems are recommended for dozers with six-way blades and excavators.
Trimble® GCS900 Dozers Systems can operate in either indicate (manual) mode or automatic mode:
Indicate/Manual Mode
Light bars and a graphical color display use the project design information and 3D GPS position and cross slope to show the operator what blade elevation and cross-slope movement is required to get to grade. The unique, dual GPS antenna system indicates the exact position, slope and cutting edge orientation for faster grading of complex designs and maintaining accurate blade cuts.
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: 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.
Using the different positioning technologies provides blade control to the following accuracies
- Trimble MS980/MS990 Smart GPS Antenna – blade control to 20-30 millimeters (0.1 foot)
- Trimble ATS Construction Total Station – blade control to 2-5 millimeters (0.007 to 0.016 feet)
- Trimble GPS with Laser Augmentation – blade control to 3-6 millimeters (0.01 to 0.02 feet)
