Outstanding pushing and ripping performance Power and innovative technology are the hallmarks of Liebherr crawler tractors. Whether for heavy ripping work, moving material or fine-grading, Generation 6 crawler dozers are powerful machines for every application. PR 736 Litronic PR 746 Litronic PR 756 Litronic

High productivity Precise control Powerful engines … Liebherr diesel engines are designed for the harsh conditions of construction sites and provide the right amount of power in every situation. Depending on the job requirements different operating modes are available for maximum power or fuelsaving operation. Excellent maneuverability When working in tight areas, the hydrostatic travel drive offers an additional benefit. All steering motions – including turning on the spot – are fast and effortless. In ripping work, the ripper can be positioned precisely between hard layers of rock and...

Cost efficiency comes standard Liebherr crawler tractors are designed from the ground up with economy in mind. A highly efficient drive concept, components with long service lives and low maintenance requirements reduce operating costs – and increase your profits.

Unrivalled economy The latest engine and exhaust technology The newest generation of Liebherr diesel engines complies with Emission Stage IV  Tier 4 final. Liebherr-SCR technology: the /  exhaust gas undergoes selective catalytic reduction through injection of urea (DEF, AdBlue®). A diesel particulate filter is not required. As a result, the engine operates in a temperature range of maximum efficiency. The constant, low engine speed, in combination with common rail injection, ensures optimised cylinder charging and, in turn, even more efficient fuel combustion. A variety of track options...

Robust design in every regard Today’s construction sites require machines with maximum versatility and ruggedness. Crawler tractors from Liebherr meet these requirements in an ideal manner: Thanks to components designed specifically for construction machinery, proven technology and innovative customer-specific solutions, you can expect maximum availability.

Liebherr driveline Rugged design Long-lasting engines Diesel engines from Liebherr have powered construction machinery around the world for decades. Developed for the harshest operating conditions, their rugged construction and low nominal operating speed guarantee maximum reliability and a long service life. Main frame with a proven box-section design The main frame is constructed using a proven box-section​ design, which provides maximum torsional stiffness and optimal absorption of forces. Cast steel is used for components subjects to high stress. Wear-free drive concept The proven...

Comfort, space and ergonomics: All in one The completely redesigned working environment offers exceptional operator comfort. With its generous space, ergonomic layout and low sound levels, the Liebherr comfort cab provides the perfect conditions for fatigue-free and concentrated work. PR 736 Litronic PR 746 Litronic PR 756 Litronic

Simple and intuitive operation Ergonomic and purposely designed The well-thought-out design of the operator’s cab provides the best prerequisites for relaxed and productive work. All instruments and operating controls are carefully organised for easy reach. An unobstructed view of the work equipment and perfect all-round visibility allows the operator to concentrate fully on the task at hand. Single-lever control All driving functions can be controlled smoothly and precisely with only one operating lever – including the “turning on the spot” function. The travel joystick is optionally...

Simple maintenance and an extensive service network Thanks to their minimal maintenance requirements, Liebherr crawler tractors make a reliable contribution to your economic success. A dense service network means short distances, efficient structures and fast response times for the user. PR 736 Litronic PR 746 Litronic PR 756 Litronic

Cost-effective maintenance Simple daily checks All items that the operator checks during daily routine inspections are readily accessible on one side of the engine. The hydraulically tilted cab provides easy access to components as well. Service work can be performed quickly and efficiently. Long maintenance intervals The maintenance intervals are optimally matched to the individual components. Maintenance-free mountings are often used in exposed areas. Hydraulic oil change intervals of up to 8,000 operating hours reduce costs and minimise downtime. Optimal planning Planned costs Liebherr...
