Liebherr PR 756 Litronic Crawler Dozer

Liebherr PR 756 Litronic Crawler Dozer

Power and innovative technology are the hallmarks of Liebherr crawler tractors. Whether for precision grading or heavy pushing, the PR 756 is a powerful machine for any application.

Intelligent Drive System

The hydrostatic travel drive operates smoothly and automatically adjusts the working speed to the load conditions. The engine’s power is always transmitted to both tracks without interruption.

Tier 4 Final Emission

The newest generation of Liebherr diesel engines complies with Emission Stage IV / Tier 4 final.The constant, low engine speed, in combination with common rail injection, ensures optimized cylinder charging and, in turn, even more efficient fuel combustion.

Optimized Equipment

L-shaped, welded push frames offer maximum strength and precise blade control. High-strength steel blades and optional, additional wear plates ensure a long service life. All ripper types are designed for heavy-duty ripping work, and areas exposed to wear are given special protection.

Ergonomically Designed Cab

The well-thought-out design of the operator’s cab provides the essential conditions for relaxed and productive work. All instruments and operating controls are carefully organized for easy reach.
