Cat® GRADE with ASSIST makes the Cat 323 hydraulic excavator more efficient and productive. This system is the first operator ASSIST feature with semi-autonomous grade control available on Cat excavators, and it automates grade adjustments that are typically achieved by the operator using manual controls. Operators at all experience levels can reach target grade as much as 45 percent faster than traditional grading.
Optimized for Cat excavators, this new technology is easy to use from the start. Integration with the familiar Cat GRADE system, display, and joysticks enables the operator to easily create simple 2D designs in the cab, press the auto button, and get to work. Operators can take advantage of the guidance features built into the base system without the need for data transfer infrastructure. For example, grade indication and audible alerts function while using ASSIST technology to perform precision work—without the need for infrastructure.
Integration with the machine and hydraulics delivers full power to the cutting edge with precise control throughout the cut, enabling the operator to create fast, accurate grades with less effort. System flexibility enables customers who work with complex grade plans to add Cat AccuGrade™ for additional 3D capability.
Automatic assistance and protection features
ASSIST technology goes to work when the cutting edge gets within 10 cm of target by locking on grade and automatically adjusting boom up/down and bucket in/out movements. The operator simply controls stick speed using a single lever, which significantly reduces manual inputs. The system also automates bucket movements to maintain a constant bucket angle, which is operator adjustable to match cutting angle to digging conditions and can be automatically recalled for next pass. To eliminate the chance of overcutting, a grade protection feature prevents the cutting edge from penetrating below grade, saving contractors the time and cost of rework, additional fuel, grade checking, labor hours and fill material.
In addition to helping customers speed grading, PROTECT features safeguard the operator and machine when working near obstacles and around utility hazards. Ceiling and Floor PROTECT prevent any part of the boom, stick, or bucket from going above or below a pre-set elevation, enabling the machine to excavate in areas with low ceiling heights such as indoors and under overpasses and near above- and below-ground utilities. Operators can quickly disable AUTO control with an override trigger at their fingertips.
