Outstanding grading and pushing performance Power and innovative technology are the hallmarks of Liebherr crawler tractors. Whether for precision grading or heavy pushing, the PR 726 is a powerful machine for any application.

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 opera­ing t modes are available for maximum power or fuel-saving 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. This makes the PR 726 an exceptionally maneuverable machine, equally at home on large...

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

Unrivalled economy The latest engine and exhaust technology The newest generation of Liebherr diesel engines comply with Stage IV / Tier 4 final emission standards utilising 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...

Robust design in every regard Today’s construction sites require machines with maximum versatility and ruggedness. The PR 726 meets these demands perfectly: 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 focused work.

Simple and intuitive operation Ergonomic and purposely designed 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 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 and fast response times for the user.

Cost-effective Optimalmaintenance planning 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 Perfectly matched components and lubricants allow for exceptionally long maintenance intervals, e.g. up to 2,000 operating hours for the diesel engine. Hydraulic oil change intervals of up to 8,000 operating hours save costs and minimise downtime. Planned...
