AccuGrade™ Systems
Grade with increased accuracy.
Caterpillar is revolutionizing the way to move material with new
technology solutions for earthmoving machines – solutions that
provide greater accuracy, higher productivity, lower operating
costs and greater profits. The AccuGrade System is designed and
integrated into the machine and hydraulic systems to create an
automated blade control system that allows operators to grade
with increased accuracy. The system uses machine-mounted
sensors to calculate precise blade slope and elevation information.
AccuGrade Laser
AccuGrade Laser uses a laser transmitter and receiver for precise
grade control. A laser transmitter on the worksite creates a constant
grade reference over the work area. A digital laser receiver mounted
on the machine captures the laser signal. The system calculates
the blade adjustments necessary to achieve grade, makes automatic
elevation adjustments typically performed by the operator and
provides automatic blade control. The operator simply steers the
machine. Automated blade control lets you achieve grade faster
and in fewer passes, reducing the need for traditional survey
stakes or grade checkers. The system also calculates cut/fill
requirements for manual blade control. Work is completed faster,
more accurately and with less manpower. AccuGrade Laser is
well suited for flat work such as concrete pads and driveways.
AccuGrade GPS
AccuGrade GPS computes the machine positioning information
and compares the position of the blade relative to the design plan.
Information is provided to the operator via an in-cab display
showing blade elevation, necessary cut/fill to achieve grade,
blade 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 for
a greater level of control. Vertical and horizontal guidance tools
visually guide the operator to the desired grade. Automated
features allow the hydraulic system to automatically control
blade adjustments to move the blade to grade. The operator
simply uses the light bars to guide the machine for consistent,
accurate grades and slopes, increasing productivity with less
fatigue. AccuGrade GPS is best used for cut and contour jobs.
AccuGrade Monitor
Caterpillar is the first to integrate this system and its monitor
into the machine’s dash for easy viewing during operation.
The AccuGrade monitor is conveniently located, allowing the
operator to view system information while keeping a straight
line of sight to the blade corners.
