A strong partner for the wind industry

As a strong partner of the wind power industry, Liebherr offers the suitable solution for a wide range of requirements. These include components which are used as pitch and yaw adjustment systems in wind turbines. Liebherr supplies mobile cranes, crawler cranes and heavy-duty offshore cranes for the assembly of wind turbines. The hoisting equipment section is supplemented by tower cranes which have been specially developed for particularly high systems.

Mixing plants from Liebherr are used to produce prefabricated concrete parts for the towers of wind turbines. In the field of automation systems, Liebherr has developed a new portal for machining rotor blades. Large diameter bearings for adjustment of the rotor blade and the yaw are manufactured on high precision gear cutting machines from Liebherr.

Maritime cranes for the wind industry

Liebherr also offers the right solution for the wide range of requirements of the wind power industry in the maritime sector. Cranes and material handling equipment are employed both at harbors and at sea, on crane ships and on floating installation platforms.

The wide range of mobile harbor cranes and ship cranes from Liebherr ideally matches the many different requirements when loading wind power components in harbors. The cranes are used to load and unload ships, low-loaders and goods wagons. This involves heavy cargo such as generators with a lifting capacity of over 70 tonnes or rotor blades with a span of more than 40m. Safety and precision are important factors. In addition to the design of the cranes, the electronic control systems are of utmost importance. These control systems one of the core competencies of Liebherr and are therefore also developed in-house..

Liebherr also offers convincing solutions for constructing wind turbines at sea. The offshore heavy duty cranes feature lifting capacities of up to 3,000 t.

Loading of wind power components at the harbor

Safety and precision are the most important criteria when it comes to transferring heavy loads in the wind power sector. The strengths of the Liebherr mobile harbor cranes are brought to bear here. Independently powered, closed hydraulic circuits employ a minimum of components and combine extremely short reaction times and maximum precision with operating reliability and safety.

The mobile harbor cranes reach maximum lifting capacities of up to 208t. In tandem operation, the patented multi-crane control system SYCRATRONIC® enables lifting capacities of up to 416t. The dynamic anti-collision control system in conjunction with Vertical Line Finder also ensures that work is carried out safely and precisely.

Heavy-duty ship cranes for transportation and loading

Liebherr supplies the CBB series, a separate line of heavy-duty ship cranes, to load and transport wind turbines. These cranes can also be equipped with the dynamic anti-collision control system for enhanced safety in crane operation. The cranes can lift loads of up to 450t.

Erection of offshore wind turbines

Liebherr's offshore heavy duty cranes feature lifting capacities of up to 5,000t and are used to erect wind turbines at sea. All requirements can be catered for: diesel-powered or electric drive units, explosion-protected cranes and cranes for ambient temperatures between +40°C and -50°C, and special lowering depths down to 3,000m below sea level.

Synchronous control for automated tandem lifts

In standard mode, each crane has to be operated by one driver for tandem lifts. The drivers are informed about the main functions of both cranes (e.g. speeds, etc.) on their respective monitors. This enables both crane drivers to control the two cranes independently, but yet coordinated.

A far more efficient variant is the "Automatic Parallel" mode with one person controlling both cranes. In this mode, the traverse remains parallel to the ship or to the initial position, and an automatic control system computes the movements of the jib heads of both cranes. Since the length and hook height difference are kept constant during movement, any unwanted diagonal pull in the cables can be ruled out.

A third option for tandem lifts is the "Automatic Rotation" mode in which the traverse can rotate. The crane driver only has to control the direction or rotation of the traverse, while the control system computes the necessary movement of the jib heads of both cranes.

Dynamic anti-collision control

The dynamic anti-collision control system manages simultaneous movements of two or more cranes. Every crane is fully protected while its performance remains constantly high.

When several cranes work simultaneously, the movements of the individual crane can be controlled based on the current position of the other cranes. The special feature of the dynamic anti-collision system from Liebherr is that it automatically computes the actual position, speed and acceleration of each crane, as well as their load torque limitation. This allows the crane driver to work absolutely safely with maximum flexibility.

Vertical line finder prevents load vibrations

The vertical line finder is an optional control aid for avoiding diagonal pull on the load. This may occur when the distance between the crane driver and the load is too long or when the center of gravity is not symmetrical.

The control system controls the position of the boom by showing the exact vertical rope position before the load is lifted. Since the load does not vibrate, the danger of damage to the load or the crane is minimized. The system also provides greater safety for the crane driver and his environment.

Efficiency for wind farms and individual installations

The economical, high-performance mobile cranes from Liebherr have proved their worth for decades in the construction of wind power plants. The cranes are available in various load capacity classes and are precisely tailored to the needs of the wind power industry. Liebherr faces the development of increasingly powerful installations and increasingly high towers by producing optimised cranes and new boom systems reaching especially high carrying capacities.

Telescopic mobile cranes (LTM) drive on public roads and can therefore be transported extremely economically. They can be quickly erected and only require very little space in this case. The telescopic mobile cranes move from site to site with a retracted telescopic boom on narrow roads at wind parks.

The basic unit of the lattice boom mobile cranes (LG) also moves on public roads. This reduces the number of transportation units compared with lattice boom crawler cranes. The lattice boom mobile crane is used during the erection of wind parks and single installations.

Components for the wind industry

Liebherr is the only manufacturer worldwide that is not only able to supply individual components as slewing bearings, slewing drives, electric motors and hydraulic cylinders, but able to supply hydraulic and electromechanical pitch systems and electromechanical yaw systems for wind turbines.

An important element of the cooperation with customers from all over the world is the applied application-specific engineering necessary for adapting and matching the individual components to each other. Liebherr works together with virtually all well-known turbine manufacturers and to date has supplied components for more than 15,000 wind turbines. The product portfolio covers components for 800 kW installations up to solutions for multi-megawatt turbines for offshore wind farms.

Pitch systems

Liebherr produces well-engineered mechanical systems for rotor blade adjustment. Electric pitch systems are based on one or more mechanical gear units with electric motor, which drive a geared large diameter slewing bearing.

Hydraulic pitch systems are based on one or more hydraulic cylinders and a slewing ring bearing without gears to adjust the rotor blade position. In either case, the precise positioning of the rotor blades results in maximum energy yield.

In pitch systems, the following components from the Liebherr portfolio can be applied:

Three-row roller bearings for higher load capacity and more cost efficiency

Wind turbines are growing steadily in an effort to attain higher energy yields. The options of adapting existing designs to the growing dimensions and more demanding load profiles has however limits - particularly in regard to rotor blade bearings. Therefore, in addition to the current single-row and double-row four-point bearings, Liebherr now also offers three-row roller bearings for pitch systems. This highly increases the potential in terms of dimensioning and load capacity.

Yaw systems

Depending on the specific system design, up to twelve or more high-performance planetary gearboxes drive a slewing bearing and ensure precises as well as reliable wind direction tracking. Liebherr configures the entire yaw system, including the necessary electric motors, precisely to the needs of the customers. This guarantees a high level of system availability.

The following components from the Liebherr portfolio are ideally suited for use with yaw systems:

Yaw module concept study

In the course of the last 20 years, variety of parts and complexity have steadily increased within the wind industry. With this study, Liebherr wants to show new ways to achieve more flexible yaw system. The result is a module which integrates all functions of the yaw system in a ready-to-install unit.

The current concept offers a wide range of advantages. It can be easily scaled in terms of size and capacity and adapted to the different turbine platforms. Additionally, the use of standard components across all platforms hold great cost savings potential. Further, the implementation of the yaw system as a ready-to-install module makes it possible to simplify processes for the turbine manufacturer along the entire value chain.

Implementation within the wind turbine

Competences

Based on a continuous quality management and the use of cutting-edge technologies, components by Liebherr meet the highest demands regarding quality and performance.

Product and system expertise

The right design and analysis of a component is decisive for its reliability and service life. For multi-megawatt wind turbines a design using Finite Element Methods (FEM) is essential, as the sensitivity to strain increases the larger the system gets. In addition, defined approval processes for new and further developments ensure optimal product configuration and thus high reliability.

High level of vertical integration

In order to ensure consistent high quality and reliability, all manufacturing processes must be optimally aligned. Hence why Liebherr improves all production processes on an ongoing basis and continually invests in cutting-edge production facilities.

Quality-oriented

Reliable components with a consistently high quality are particularly important for wind turbines in order to avoid long production downtimes and high logistics costs. To ensure that the quality standards achieved in the construction using Finite Element Methods (FEM) and Failure Mode Effects Analysis (FMEA) are also maintained in subsequent processes, all company processes are designed to maintain quality.

    Quality concrete for wind power installations

    The towers of modern wind power generators are made out of prefabricated concrete parts. These concrete components, whose form and strength are subject to extremely high standards, are prefabricated in prefab factories and then assembled at the construction site.

    Liebherr concrete mixing systems employing their own mixer systems supply the concrete for these prefabricated parts. They can be connected directly to the production halls and supply the concrete by a bucket conveyor directly from the mixing plant.

    The Litronic-MPS process control system in conjunction with the Litronic-FMS moisture measurement system guarantees perfect concrete quality in the correct consistency.

    The Liebherr tower mixing systems of the type Betomat and the horizontal series of Betomix systems are both well-suited for the task of producing concrete for wind power tower segments.
