Within only two months, the 70 t dozer has achieved over 1.000 operating hours with outstanding productivity and physical availability. It has been proven that the PR 776 outperforms its peers in terms of tonnes per litre of fuel burned and overall costs per tonne of material pushed. The constant power management of the hydraulic system ensures low fuel consumption and enables a reduction in the carbon footprint. Additionally, a Liebherr instructor was dispatched on site to train the mine’s dozer operators and enable them to better understand the operating procedures of the PR 776. The dozer operators greatly favoured the PR 776’s integrated ROPS/FOPS cab feature, which provides an all-round visibility and further enhances workplace safety.

Thanks to this project, Liebherr Indonesia is now able to explore promising opportunities to further increase the sales of the PR 776 on the Indonesian market. Max Muench further mentioned: “We are confident that our ultra-class dozer has made and will continue to make its beneficial features clear to a wider audience. The second and third PR 776, which will be delivered to other Indonesian mining concessions shortly this year, are already a favourable indication to us.”

The Liebherr PR 776 is the world’s largest hydrostatically driven mining dozer. The machine enables the customer to operate with class-leading efficiency and consistent performances. Thanks to the intelligent drivetrain and the powerful Liebherr diesel engine, operators benefit from high torque and efficiency in every situation and at all times.
