Profile

For 70 years, the Liebherr name has stood for excellent, benefit-oriented products and services. The Liebherr Group is not only one of the world’s leading manufacturers of construction machinery; it is also a major supplier in many other fields of engineering like the wind industry.

Liebherr is a powerful partner for the wind industry and offers convincing solutions for a wide range of requirements: On the one hand, components manufactured by Liebherr are installed directly into wind turbines. On the other hand, the company’s mobile, crawler, offshore and tower cranes, for example, are used for erecting wind turbines and constructing wind farms.

Offering slewing bearings, slewing drives, electric machines, frequency converters and hydraulic cylinders, Liebherr is the only manufacturer worldwide that provides not only single components, but also entire systems for electromechanical and hydraulic pitch and yaw adjustment in wind turbines. For rotor blade adjustment, Liebherr offers moment bearings in two main designs: as double-row tapered roller bearings or triple-row roller bearing slewing rings. The portfolio also includes compact full scale converter solutions for wind turbines with a capacity from 2 to 5 MW.

One of the major elements of cooperation with customers from all over the world is application-specific engineering to perfectly adapt each of the components. In the wind industry, Liebherr collaborates with nearly all leading turbine manufacturers and so far has equipped numerous wind turbines with its own components. The product portfolio comprises components for turbines from 800 kW up to solutions for multi-megawatt offshore turbines.

With their innovative technology, high quality, profitability and longevity, mobile and crawler cranes from Liebherr own a leading position in the world market. For decades, they have also been proving their value in the construction of wind farms. As well as telescopic mobile cranes, Liebherr also provides lattice boom mobile cranes and crawler cranes to erect wind power systems, in a variety of performance classes, specifically matched to meet the needs of the wind power industry. The Group keeps pace with the development of larger and more efficient turbines as well as the increasing hub heights by offering cranes with optimized performance and new jib systems, reaching higher lifting capacities.

Cranes on narrow crawler travel gears especially developed for the construction of wind farms can move on the narrow tracks from one unit to the next in full setup condition, that is including jib and full ballast. This is especially economical, because machine and equipment have to be mounted only once.

For erecting wind turbines with a hub height of 110 m or more in low-wind areas, Liebherr also offers specially developed tower cranes with lifting capacities of up to 125 t. They are mounted on the wind turbine and are configured in a way that the necessary lifting height can be reached by guying the crane to the mast at one point only. Advantages are reduced space required by the crane, the ability to work despite high wind speeds and sensitive lifting of loads using Micromove.

Liebherr also offers efficient solutions for the erection of offshore wind turbines. Heavy duty cranes for offshore applications are able to lift up to 5,000 t and reach a lifting height of 180 m above deck. Thereby the Group’s offshore portfolio meets challenging requirements, such as the provision of diesel or electrical drive units, explosion protected cranes and cranes for ambient temperatures between +40 °C and -50 °C. Liebherr cranes are not only used successfully for the construction of offshore wind turbines, but also on oil and gas platforms, for offshore construction, pipe-laying or subsea operations down to 3,600 m below sea level.
