Cat Grade with 3D for motor graders is designed to improve grading efficiency, accuracy, and productivity of automated grading systems without the limitations associated with GPS masts. The new integrated mast-less grade system can be installed and calibrated at the factory on new machines, or as a field retrofit for existing models. Retrofit kits are available for pre- and post-2019 M Series models equipped with or without the Attachment Ready Option.
Previous GPS systems for motor graders, says Caterpillar, required 6-foot-tall masts mounted to the ends of the moldboard, exposing the components to potential damage and theft. The antennas/receivers were often removed and installed daily, limiting the machine’s time in the dirt, and the masts limited the blade’s range of motion. The masts also limited the types of applications for the motor grader, says Caterpillar. An E-Fence feature on factory installations of Cat GRADE with 3D is designed to prevent the moldboard from contacting the tires or ladder, and to prevent the circle from potentially damaging to the link bar.
Cat 140, 150, and 160 motor graders will be the first models equipped with the new mast-less Cat GRADE with 3D.
