PR 776 highlights:

Push more with minimised operator input

Generation 8 dozers offer a significant increase in performance thanks to operator assistance systems.

Moving more for less

Liebherr diesel engine with hydrostatic transmission reducing fuel burn rate.

Engineered for innovation

The new generation of dozers is distinguished by its various technical innovations offering a longer commercial life expectancy.

The PR 776 G8 has multiple possibilities within our mining team to help with both maintaining floors, construction of ramps to design and possibly remote operating which will help reduce potential injuries and bring down costs.

A decade of innovation and performance

Since its debut at Bauma 2016 as the world’s first hydrostatic mining dozer in the 70-tonne class, the PR 776 has continued to impress. Within its first four years on the market, its ability to operate in the most demanding conditions led to more than 100 of these machines operating across all continents. Over the years we continued to optimise our original design and, in 2024, we launched the PR 776 G8. This Generation 8 dozer included all previous product updates and was also compatible with our Operator Assistance Systems and LiReCon teleoperation system.

In 2026, we celebrate the PR 776’s 10th anniversary and more than 300 machines delivered worldwide – a milestone built on innovation, performance and close collaboration with our customers.

Full power: PR 776 with hydrostatic drive

Innovation, our key to performance

Hydrostatic travel drive system

The Liebherr hydrostatic drive system distinguishes itself among dozers in its class. Its high efficiency spans the entire vehicle speed range, resulting in minimal fuel consumption and low CO₂ emissions. Unlike traditional systems, the hydrostatic drive eliminates components such as torque converters, multi-ratio transmissions, service brakes, and steering couplings.

This innovative design optimises performance while minimising environmental impact!

Advantages:

Smooth and continuous speed adjustment
Consistent power stability
Precise control and easy navigation
Quick response with simple joystick inputs
Reliabale braking system

LiReCon

The Liebherr Remote Control System will revolutionise daily work routines for Crawler Dozers. Using the Liebherr teleoperation stand and high-resolution video signal, this system opens up completely new horizons: ranging from flexible remote control to exploiting areas of operation that are difficult to access. It improves safety and increases comfort and productivity, particularly when working in hazardous environments.

Advantages:

Unrivalled operating comfort
The safest operating mode
Optimising operating times

Operator assistance systems

Liebherr's generation 8 dozers offer exceptional driving comfort and performance with advanced assistance systems.

The "Free Grade" system actively stabilises the blade for precise levelling.

"Definition Grade" enables 2D surface modelling without a rotating laser, using a reference point. Automatic blade lowering ensures easy accuracy over long distances. "AutoBladePitch" enhances performance by automating blade movements for loading, carrying, and spreading.
