Diesel Engines At the sites in Bulle (Switzerland) and Colmar (France), Liebherr develops and manufactures high-performance and robust combustion engines for diverse applications in building construction, mining, in special vehicles, stationary applications, as well as agriculture and forestry machinery. Liebherr engines can be adapted precisely to the respective requirements as not only the engine block is from in-house development and production, but also the Common Rail system and the engine control system.

Efficiency and reliablility Liebherr diesel engines have a high specific power and high torques in a wide speed range while retaining very good operating values. They can withstand the toughest requirements such as extreme outside temperatures, and can be used at very high altitudes. Smooth running State-of-the-art analysis methods and design procedures are used to minimize vibration and noise emissions, and to improve rigidity and material distribution. This ensures that engines run absolutely quietly and reliably even when used continuously with fluctuating loads. Modular engine design...

The high-performance Liebherr gas engines impress with their high level of efficiency and reliability. Optimised for operation with natural gas, biogas and special gases, they are suitable for diverse applications. Customers particularly appreciate that Liebherr supplies the units ready for installation.

High availability Thanks to the high availability of gas engines, short downtimes and low maintenance as well as operating costs are guaranteed. The key contributor being the accurate dimensioning of the engines, their sophisticated control system and engine peripherals, high mechanical strength and high resistance to wear. The operating status of the engine, ignition system and Lambda control is continuously monitored by the engine control system. Performance and efficiency Liebherr gas engines are particularly impressive due to their performance, a favourable ratio between electrical and...

Fuel Injection Systems The operational spectrum of Liebherr Common Rail systems extends from machines and commercial vehicles for on- and off-highway applications right up to stationary applications and includes the medium and heavy duty ranges. Compactly designed single components with above-average performance integrated into modular system solutions make Liebherr’s injection technology so flexible. Thereby they support compliance with current and future emission standards.

Competence for top quality Liebherr’s great engineering and system expertise as well as its high degree of vertical integration provide high flexibility in integration of Common-Rail systems in various engine variants. Decades of experience in the development and production of diesel engines for the harshest environmental conditions ensure the ultimate high-performance and reliability of injection systems over a long service life. Efficiency and performance Liebherr Common Rail systems deliver a high injection pressure of up to 2,500 bar and ensure high efficiency and low fuel consumption...

Axial Piston Pumps and Motors At its site in Bulle, Switzerland, Liebherr designs and manufactures axial piston pumps and motors in swashplate design for open and closed circuits. Available as constant or variable units, the components offer a wide variety of control functions and drive through options. Valve or control oil pumps can be integrated. These compact units thus permit a very flexible machine design.

Long service life and reliability All components are machined with high precision and quality on state of the art production plants. The optimum design of the individual parts and special materials guarantee the virtually wear-free reliable operation of pumps and motors in continuous operation under pressures of up to 450 bar. Optimised efficiency and quiet operation Modern design and simulation programs (FEM and CFD) are used in the design and calculation of hydraulic pumps and motors, resulting in the optimization of the housing construction design, flow paths and commutation. These, in...

Hydraulic Cylinders and Power Units Since 1958 the Liebherr Group has been developing and producing hydraulic cylinders at the site in Kirchdorf an der Iller, Germany. The product portfolio reaches from standard cylinders to large heavy duty cylinders and suspensions through to high-stress lightweight and special cylinders. In addition to hydraulic cylinders for mobile and stationary applications, as well as shock absorbers, Liebherr also offers tailormade hydraulic power units and other components for hydraulic system solutions.

Quality and Economy State of the art production facilities enable variable batch sizes, swift delivery and short reaction times. Consistent production focusing on the core competencies of piston rods, cylinder tubes, assembly, painting and inspection at each stage in the production process ensures a high level of quality, economic efficiency and reliability of the products. High Availability and Longevity Liebherr hydraulic cylinders are noted for careful material selection, high manufacturing precision of components, customised sealing systems and top surface finishing quality. The...
