The Caterpillar AccuGrade grade control system (Circle 911) simplifies grading, improves accuracy, increases productivity and minimizes material overage. Several different AccuGrade systems are available to enable contractors to match the system to the job requirements.

The AccuGrade GPS control system is the best solution when the construction site involves contours. The system uses GPS technology to compare the blade position to a three-dimensional computerized site plan and signals the operator or hydraulic system to raise or lower the blade to achieve the design requirements.

AccuGrade ATS is a high-accuracy dynamic tracking system that uses an Advanced Tracking Sensor (ATS) to track the motor grader and monitor blade positioning. An ATS instrument on the worksite is used to track a target, which is mounted on the blade, to determine precise 3D positioning.

AccuGrade Sonic uses ultrasonic waves to calculate elevation from a physical reference point, such as a stringline, curb or gutter, to maintain elevation.

AccuGrade Cross Slope is a grade control system designed to control surface cross slope. Machine-mounted sensors are used to calculate necessary blade slope positioning to achieve the desired cross slope of the surface.

The AccuGrade Laser Grade Control System is designed for a wide range of construction earthwork applications requiring tight tolerances. The dual laser system is ideal for fine grading of sites with flat, single or dual slope surfaces.
