Komatsu GD655-7 Motor Graders with 2D Cross Slope System
Precise control for the perfect crown
A 2D cross slope system on a motor grader allows operators to control the slope angle more easily for the entire length of the moldboard while effortlessly adjusting on the fly. That’s why the system is a standard feature on Komatsu GD655-7 motor graders.
The operator controls the height of the moldboard by adjusting just one end while the 2D system automatically maintains the desired cross slope angle. This allows operators to focus more on the leading or trailing end of the blade and the machine’s travel path. Automatic or manual mode can be set for either end of the moldboard.
With the 2D cross slope system, operator fatigue and stress can be reduced when making precision passes. The system also allows for quick slope angle when cutting road crowns and shoulders. It works even if the machine is articulated and does not require daily recalibration.
Insider Tip: “The memory presets and the slope match features make it easy for the operator to quickly maintain slope angle when returning in the opposite direction,” said Nathan Repp, product marketing manager, Komatsu. “One of the memory presets could be a mirror angle setting, and the slope match setting means that the operator can set the blade on an existing slope and use it as the base setting for the moldboard cross slope angle.”
