The world’s biggest hydrostatic dozer

Highlights

Liebherr Mining Dozers rip, push, stockpile, clear and reclaim in mines all around the globe. As the world’s biggest hydrostatic dozer, the Liebherr PR 776 gives mining customers an edge thanks to class-leading efficiency and constant power due to the intelligent driveline and hydraulic systems.

    PR 776 highlights:

    Push more with minimised operator input

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

    Technical data

    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.

    Advantages:

    • No need to set up GNSS or LASER
    • Quick and easy creation of flat pads
    • Minimised operator input
