Trimble GCS900

Caterpillar Accugrade GPS Grade Control System
The AccuGrade GPS Grade Control System is a high technology machine control and guidance system that allows dozer operators to grade with increased accuracy, without the need for survey stakes. Digital design data, in-cab operator guidance features and automatic blade controls help the operator achieve grade faster, meaning higher productivity, lower operating costs, and greater profitability.

AccuGrade GPS uses advanced Global Positioning System (GPS) technology to deliver precise blade positioning and control information to the cab. Using machine-mounted components, an offboard GPS base station, and Real Time Kinematic positioning, GPS provides the information necessary for the system to accurately determine blade positioning with centimeter level accuracy.

The AccuGrade system computes the positioning information on the machine, compares the position of the blade relative to the design plan, and delivers that information to the operator via an in-cab display. Information such as: blade elevation; how much cut/fill is necessary to achieve grade; visual indication of the blade’s position on the design surface; and a graphical view of the design plan with machine location.

AccuGrade GPS puts all the information the operator needs to complete the job in the cab, resulting in a greater level of control. Vertical and horizontal guidance tools – in-cab display and light bars – visually  guide the operator to desired grade. Automated features allow the hydraulic system to automatically control blade lift and tilt to move the blade to grade. The operator simply uses the guidance tools to steer the machine for consistent, accurate grades and slopes all day long resulting in higher productivity with less fatigue.

The AccuGrade GPS system is integrated into the machine electronics and hydraulic systems for optimum blade response time and maximum grade control in all conditions. The system integrated cab and joysticks allow even inexperienced operators  to produce high quality results with minimal training.

Applications
AccuGrade GPS is designed for a wide range of construction earthwork applications, from bulk clearing with high production rates to finish grading with tight tolerances.

Flat, single and dual sloping planar designs, such as building pads, parking lots, roads and highways, can be created on-board the machine using the AccuGrade GPS system.
