Liebherr-Werk Bischofshofen GmbH is set to unveil groundbreaking advancements at Bauma 2025, introducing the “Liebherr Autonomous Operations” system and the first large wheel loader with a hydrogen engine. The autonomous solution, designed for repetitive and hazardous tasks, enables fully driverless operation, while the L 566 H wheel loader represents a significant leap in alternative drive technologies. This innovative machine, powered by a hydrogen engine, aims to eliminate greenhouse gas emissions and significantly reduce nitrogen oxide emissions. Notably, Liebherr’s autonomous system remains in contention for the prestigious Innovation Award in the “Digitalization” category at Bauma, the construction industry’s leading trade fair. Following the event, Liebherr will conduct a two-year trial of the hydrogen-powered L 566 H at STRABAG, a major European construction technology group.
Revolutionizing Wheel Loader Operations with Autonomy
“Liebherr Autonomous Operations” is designed to enhance efficiency and safety by automating monotonous tasks such as loading hoppers and material transport. This innovation helps address labor shortages for routine jobs, allowing employees to focus on more complex and strategic tasks. Dr. Manuel Bös, Head of Emerging Technologies at Liebherr-Werk Bischofshofen GmbH, highlights that this technology not only optimizes productivity but also ensures worker safety by operating in hazardous environments like quarries. Visitors at Bauma 2025 will witness live demonstrations of the autonomous wheel loader prototype, which will undergo further field tests before market availability.
User-Friendly and Adaptive Technology
Operators can efficiently schedule tasks for the autonomous wheel loader using Liebherr’s “Autonomous Job Planner” web application, which requires minimal IT skills. The system utilizes 3D environmental sensors to detect surroundings, obstacles, and piles, eliminating the need for external surveying tools like drones. Furthermore, unlike conventional GPS-dependent systems, Liebherr’s autonomous technology operates seamlessly in various environments, including industrial halls, underground locations, and high quarry faces. This versatility ensures uninterrupted material handling, even in challenging conditions.
Maximizing Efficiency and Cost Savings
The autonomous system guarantees consistent performance throughout operations, optimizing efficiency and planning. By reducing component wear, tire degradation, and fuel consumption, the technology helps lower ongoing operating costs. Another advantage is the seamless transition between manual and autonomous operation, allowing flexible machine utilization.
The L 566 H: A Game-Changer in Hydrogen-Powered Wheel Loaders
Liebherr is embracing multiple drive technologies, with extensive research identifying hydrogen propulsion as an optimal solution for large wheel loaders. The L 566 H, based on the L 566 XPower, integrates a power-split XPower travel drive, ensuring robust and efficient performance. While battery-electric solutions are ideal for smaller vehicles up to 15 tonnes, hydrogen engines offer a superior alternative for heavy-duty machines with high energy demands, such as those weighing up to 40 tonnes.
Developed at Liebherr’s engine plant in Bulle, Switzerland, the hydrogen engine in the L 566 H promises zero greenhouse gas emissions and minimal nitrogen oxide emissions. Additionally, its thermal and mechanical characteristics are comparable to traditional diesel engines, simplifying the transition to alternative fuels.
Pioneering Decarbonization in Construction
As part of a long-term sustainability initiative, Liebherr is partnering with STRABAG to test the L 566 H at the Gratkorn quarry in Austria over two years. This hydrogen-powered wheel loader is expected to reduce CO₂ emissions by up to 100 tonnes annually, equivalent to approximately 37,500 liters of diesel. The pilot project demonstrates how alternative fuels can play a crucial role in decarbonizing the construction sector, a field where achieving carbon neutrality has been challenging. By utilizing green hydrogen—generated from renewable sources like wind, water, or solar energy—Liebherr and STRABAG are paving the way for a more sustainable future in construction.
