The new PR 776 is powered by a Liebherr 12-cylinder diesel engine developing 565 kW (768 HP / 759 HP). The PR 776 has a maximum operating weight of 74t and is equipped with blade capacities of 18m³ / 23.5yd³ (semi-U blade) or 22m³ / 28.8yd³ (U blade).
Efficiency and performance: Modern, infinitely variable drive concept
The ECO function is standard for all Liebherr Generation 6 crawler tractors – including the new PR 776. It allows operators to choose between high performance and maximum efficiency. The ECO control system enables greater travel drive efficiency in light to medium operations, and also provides greater fuel savings.
Maximum safety with excellent view of equipment and surrounding area
The modern design of the new Liebherr PR 776 offers all-round visibility for safe and efficient day-to-day operation. Safety is enhanced by the excellent visibility of the worksite, the blade and rear ripper which is assured by the larger panoramic windows and downward slopes on the PR 776. A new feature in this class is the ROPS / FOPS protection integrated directly in the cab structure as standard for Liebherr crawler tractors.
Reliability: Robust components manufactured in-house
Liebherr Diesel Engines have powered construction machinery around the world for decades. Developed for tough conditions, they guarantee maximum operational safety, reliability and a long service life thanks to the robust design and state-of-the-art technology. With the tried-and-tested hydrostatic Liebherr travel drive, components with high wear such as multi-speed gearboxes, steering clutches or service brake are not installed. Instead, the high-quality hydraulic pumps and engines work practically wear-free and are particularly reliable.

Superb performance in bulldozing and ripping operations
Power and innovative technology are essentially the hallmarks of Liebherr crawler tractors. Either in heavy-duty ripping work, transporting materials or grading, the PR 776 is an extremely powerful machine for any application.
Cost efficiency comes as 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.
Components for ultimate performance and service life
The extraction industry imposes very high demands on the performance and reliability of the ma-chines and vehicles it uses. The PR 776 meets these demands perfectly. Its components were specifically developed for arduous working environments. The same is true of its carefully crafted technology and innovative and detailed solutions. All of which combine to deliver ultimate levels of operational availability.
Maximum driver comfort for more productivity
The completely redesigned working environment offers exceptional operator comfort. With its spa-cious ergonomic layout and low sound levels, the Liebherr comfort cab provides the perfect condi-tions for fatigue-free, focused work to optimise productivity.
