Liebherr has expanded its robust lineup of 8th generation crawler dozers with the introduction of the PR 776 G8, a state-of-the-art mining dozer designed for the toughest quarrying and mining operations. This new flagship model joins the PR 766 G8 and the smaller PR 756 G8, together forming a comprehensive range of cutting-edge machinery tailored for high-demand environments.

Unmatched Efficiency with Hydrostatic Drive

The PR 776 G8 stands out as the only mining dozer featuring a hydrostatic travel drive, ensuring best-in-class efficiency. Combining powerful Liebherr diesel engines with a standard ECO mode, operators can effortlessly switch between high performance and maximum fuel efficiency. With an impressive average fuel consumption of just 38 liters per hour, the PR 776 G8 sets a new benchmark for dozing operations in the mining industry.

Advanced Operator Assistance Systems

This crawler dozer integrates innovative Operator Assistance Systems (OAS) that were previously exclusive to smaller models. The systems provide two levels of assistance: ‘Free Grade’ for active blade stabilization during fine grading, and ‘Definition Grade’ for automatic blade positioning when creating precise 2D grades. Additionally, the ‘Auto Blade Pitch’ system allows operators to save and access three optimal blade positions at the push of a button, facilitating perfect material penetration, optimal transport, and swift clearing at the end of the push.

Durability and Low Wear Components

One of the key features of the PR 776 G8 is its reliable hydrostatic drive system, which eliminates high-wear components like gearboxes and service brakes. Instead, high-quality hydraulic pumps and motors ensure a virtually wear-free operation, resulting in exceptional dependability. Liebherr also offers factory-fitted adaptations tailored for various environmental conditions, making these dozers versatile for desert and extreme cold operations alike.

Maintenance Made Simple

Liebherr has designed the PR 776 G8 with optimal service accessibility in mind. Key features include centralized maintenance points, wide-opening access flaps, and a standard tiltable operator’s cab. An optional swing-out fan aids in cleaning, allowing for quick and efficient maintenance. With extended maintenance intervals for operating fluids like hydraulic and engine oil—up to 8,000 operating hours when using Liebherr Plus oils—this dozer minimizes downtime and keeps operations running smoothly.

Operator Comfort and Safety

Cabin comfort is paramount in the PR 776 G8. Operators benefit from a single joystick control system, enhancing convenience, while safety is bolstered by 360° visibility around the blade and ripper, thanks to large panoramic windows and an integrated ROPS/FOPS cab structure.

In challenging work environments, the Liebherr Remote Control (LiReCon) system significantly boosts safety and productivity. This system includes a state-of-the-art teleoperation workspace with cameras for various angles, microphones for sound monitoring, and a radio link for communication. By allowing operators to control the dozer remotely, LiReCon reduces idle time and enables access to hazardous areas, expanding the range of applications for Liebherr mining dozers.

Conclusion

In summary, the Liebherr PR 776 G8 crawler dozer is engineered for ultimate efficiency, advanced technology, and operator comfort. With its robust features and exceptional performance capabilities, it is set to redefine mining operations.
