To be successful despite the constantly increasing cost and time pressures, construction machinery must meet the highest

demands regarding working speed and accuracy. Increasingly, automatic grade control systems are utilized to improve the

productivity of operator and machine.

They utilize existing planning data to automatically guide the machine attachments when removing or spreading material.

With the aid of the most up-to-date technology, complex surfaces and exact grades can be produced quickly and precisely.

consumption

More accurate grading improves material economy •

due to controlled material usage

Signiﬁ cant cost savings for the owner and •

Liebherr crawler tractors are eminently suitable for application of automatic grade controls, thanks to their innovative

drive system. The hydrostatic drive provides uninterrupted power without the need to shift gears. Due to the long tracks

and the perfect match of front attachment, working hydraulics, and base machine, exceptional grading properties are

ensured.

Depending on the type of application, various technologies are utilized. To simplify the installation, Liebherr offers a

number of installation kits. They ensure that the retroﬁ t installation of the grade control system on the crawler can be

completed without requiring access into the interior of the machine.
