Liebherr updates G8 crawler excavators with assistance systems

New energy management, 2D/3D-ready machine control, automated digging support and integrated weighing expand applications in earthmoving and construction logistics.  www.liebherr.com Liebherr is extending the functionality of its Generation 8 crawler excavators with additional operating modes and assistance systems aimed at improving fuel efficiency, machine control accuracy and operator support on construction and earthmoving sites. The update applies to the R 922 to R 945 G8 range and introduces new standard and optional features, including energy management, guidance, automated bucket filling, load weighing and 360° visibility. LPE mode targets fuel efficiency via hydraulic–engine optimisation A key change is the introduction of LPE Mode (Liebherr Power Efficiency) as a standard feature across the R 922 to R 945 G8 models. Liebherr describes LPE as a patented system that continuously optimises the interaction between the machine’s hydraulics and diesel engine as part of its energy management strategy. In practical terms, LPE is designed to reduce fuel consumption by up to 10% while maintaining productivity. The mode can be activated easily and supports saving preferred operator settings. For certain movements, the system can also provide a temporary performance increase, intended to support faster and more precise execution of key operating sequences. Ground-level DEF filling designed to reduce handling risk The update also includes a diesel exhaust fluid (DEF) filling pump intended to improve safety and ergonomics during refilling. The system enables direct filling from ground level, eliminating the need for the operator to climb onto the upper carriage. Liebherr positions this as a measure to reduce risks linked to overflow, contamination and corrosion. Used together with the machine’s fuel filling pump, the setup is intended to shorten refuelling procedures and reduce downtime on demanding jobsites. Leica 2D machine control becomes standard, with 3D upgrade paths For grading and earthmoving accuracy, the Leica 2D control system is now offered as standard equipment. The user interface is integrated into the machine’s main display and uses colour-coded visuals to support levelling and excavation work. Liebherr specifies a system accuracy of ±2 cm, positioning the 2D guidance solution as a tool for repeatable quality in typical earthmoving tasks. The configuration can be adapted to different projects, and the system can be expanded into “3D-ready” options from Leica—either passive 3D or semi-automated 3D functions—supporting higher precision requirements and more complex site conditions. Bucket Filling Assistant automates digging cycles withan anti-stall function Liebherr is also adding the Bucket Filling Assistant (BFA), which is designed to automate the bucket filling process to stabilise excavation cycles. After a joystick command, the bucket filling sequence runs fully automatically, aiming to deliver consistent digging performance without continuous manual correction. The BFA includes an anti-stall function intended to prevent bucket blockage. It can be supplied factory-installed or activated through a software update. For evaluation on site, Liebherr offers 500 hours of complimentary BFA use, allowing operators to test the workflow benefits within real excavation operations. Integrated weighing supports traceability via Liebherr Connect The Generation 8 machines also receive a weighing device integrated into the main display as standard. Liebherr specifies a weighing precision of ±2% in real time across the full loading cycle. For reporting and traceability, the system supports automated data recording via Liebherr Connect, depending on licensing. The intended use case is optimised truck loading—reducing overloading risk and helping operators avoid potential penalties. Like the BFA, this function can be delivered from the factory or enabled via software update, and Liebherr provides 500 hours of free use for testing. Skyview 360° adds heated wide-angle cameras for all-around visibility For safety and jobsite awareness, the Skyview 360° assistance system introduces a four-camera setup using heated, high-resolution wide-angle cameras to improve visibility—including blind spots—during cold-weather operation. Operators can select from six different views or use a computer-generated 360° bird’s-eye view, displayed on an additional adjustable screen. Liebherr offers Skyview 360° as a factory option or retrofit package, and states the system is compatible across all Liebherr G8 excavators. The retrofit kit includes cameras, a computer unit, displays and installation accessories, with the goal of simplifying the replacement of existing camera systems. Generation 8 platform expands after 2019 market launch Liebherr introduced the Generation 8 crawler excavators globally in 2019, positioning them for earthmoving applications with redesigned machine architecture intended to improve er
