Trimble GCS900 Grade Control System For Grading Applications

Trimble GCS900 Grade Control System: 3D Automatic Control

One of the most revolutionary changes in the way earthworks are performed has been the introduction of 3D systems originally 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 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 advanced 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 kit 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 Trimble GCS300 through GCS600 Grade Control System. And with its CAN-based design, the GCS900 can be easily moved from machine to machine, as needed.

Trimble GCS900: How Does it Do That?

The positioning sensors are used to compute exact position of the blade or bucket many times per second. 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 SV170 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 light bars are separate from the display so that the operator can focus on safely operating the machine by having the light bar in the field of view.
The MS980 GPS Smart Antenna, the SR300 laser receiver and the ATS Construction Total Station all connect to the same cable harness. This allows the contractor to easily switch between sensors; the contractor has the flexibility to use their system for all phases of earthmoving---from mass excavation through to finished grading.

Trimble MS980 Smart GPS Antenna

The MS980 Smart GPS Antenna is an integrated GPS receiver and antenna designed to provide maximum portability and flexibility. It has been specifically designed for machine installation in the harsh construction environment, and has extensive field- proven performance in mining and construction applications. 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 or bucket are measured. This is especially advantageous for complex design surfaces such as super-elevation grading tasks. The MS980 can also be used in a single antenna configuration on scrapers and motor graders. Ideal for a wide range of machines, you can use the MS980 Smart GPS Antenna for GCS900 blade control to 20-30 millimeters (0.1 foot).

Trimble SR300 Laser Receiver

The Trimble SR300 Laser Receiver is available as an option for use with a GPS-based GCS900 system to provide improved vertical accuracy. This laser receiver is ideal for GPS operations with tight tolerances. The 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. You can use the SR300 with the GL700 series of Grade Lasers for GCS900 blade control to 3-6 millimeters (0.01 to 0.02 feet).

Trimble ATS Construction Total Station

The Trimble ATS Construction Total Station includes a total station, a license-free radio link and an active target mounted to the motor grader blade. The ATS 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. Ideal for motor graders performing fine or finished grade, you can use the ATS Construction Total Station for GCS900 blade guidance to 2-5 millimeters (0.007 to 0.016 feet).
