The LR 1300 SX crawler crane is used primarily in the area of wind turbine assembly and servicing. It is equipped for these operations with a narrow, telescopic undercarriage in order to ensure economical positioning under restricted space conditions.

The LR 1300 SX is driven by a Liebherr diesel engine developing 450kW / 612PS. The crane is equipped with two crane winches which each have a lifting capacity of 15 tonnes and feature high rope speeds for this wire rope hoist. Fast lifts and high lifting performance are therefore attained even with multiple reevings.

One of the characteristic features of the LR 1300 SX is its innovative boom system. In particular, the newly developed design of the SX boom ensures higher lifting capacities which are required during the erection of wind turbines. Additionally, there is a new heavy-duty jib which is 8 m long and is structurally designed for a maximum lifting capacity of 117 t. The heavy-duty jib develops its full capability in conjunction with long booms and derrick equipment. When an 80m main boom is combined as standard with a heavy-duty jib, the LR 1300 SX attains lifting capacities of more than 80t.

The standard width across the tracks of the LR 1300 SX is 8m. However, the undercarriage can be contracted to a width of 4.8m. Automatic track width adjustment enables the crane to travel fully equipped, i.e. including the boom and with full ballasting. The LR 1300 SX therefore offers extraordinary mobility for a machine in this lifting capacity category.

The dismantled LR 1300 SX with a maximum transport width of 3m can be inexpensively transported on standard low-loaders.

The LR 1300 SX is equipped with the latest generation of the Liebherr control system based on CANBUS technology. This system automatically computes the lifting capacities during operations, this ensuring optimum utilization of the crane.

With the 1000 EC-B 125 Litronic, Liebherr has developed a crane for very economical erection of wind turbines with hub heights in excess of 120m. The crane offers a new and highly economical hoist solution for wind turbines with hub heights over 120m.

For other applications, e.g. in power station and plant construction, the Flat-Top crane can also be used with radii of 41.5m and 46.5m.

The infinitely adjustable crane drive units ensure high working speeds. Thanks to the MICROMOVE fine positioning mode, concrete rings, nacelles and rotor blades can be positioned and set down with millimeter precision.

A concept for extremely fast, safe and simple climbing was developed for the 1000 EC-B 125 Litronic. Twice as fast as with conventional climbing equipment, the crane climbs to a free-standing hoist height of over 100m at wind speeds of up to 18m/s.

Tower cranes provide the driver with an ideal view of the load. This makes it easier for the driver and erectors to communicate when erecting wind turbines.

The transport properties of the new 1000 EC-B 125 Litronic have also been optimized. Most of the various crane sections can be transported using semi-trailers without specialist transport equipment. The boom parts of the large crane can be placed inside the tower elements for transport.

Liebherr has developed a special-purpose tower crane for the erection of wind turbines with hub heights of 110m or more in low-wind areas. This crane of the type 630 EC-H 70 Litronic is mounted on the foundations of the wind turbine and is configured in such a way that the necessary lifting height can be reached by guying the crane to the mast at one point only. The 630 EC-H 70 Litronic is therefore capable of lifting loads up to 70t.

Wind power generators in low-wind areas do not normally form part of large wind parks, but are erected in forest areas or regions where access is difficult. Tower cranes provides special advantages in these locations. Firstly, transportation vehicles with special permits are not required for delivery and removal on roads that frequently do not have special surfaces. Secondly, the crane and the wind turbine can erected on a comparatively small surface area.

The 630 EC H 70 Litronic crane achieves a lifting height of 151m with only one guying attached to the wind turbine tower. Up to a lifting height of 93.1m, it operated freestanding for this type of work.

The crane is mounted on a reusable foundation frame. Years later, smaller tower cranes can also be inexpensively mounted there in order to carry out maintenance and repair work on the wind turbine.

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:

• Large diameter bearings
• Gearboxes
• Hydraulic cylinders
• Electric motors
• Integrated lubrication system

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.

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:

• Large diameter bearings
• Gearboxes
• Electric motors
• Integrated lubrication system

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.

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.

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.

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.
