The fourth generation of the owner’s family of crane and heavy haulage contractor Wiesbauer GmbH made their first trip to the Liebherr plant in Ehingen to take delivery of a crane. This traditional family-run company based in Bietigheim-Bissingen (Baden-Württemberg) has significantly upgraded its crane fleet. Not only did the Swabian company take delivery of another LTM 1750-9.1 mobile crane, but an LTR 1220 telescopic crawler crane and a new 1000 tonne crawler crane were also added to its fleet. This LR 11000 celebrated a fantastic premiere in summer by hoisting a bridge to the north-east of Stuttgart.

When a major bridge construction project was started two years ago by Deutsche Bahn in southern Germany, Wiesbauer and its Liebherr LR 11000 crawler crane received the order to remove a 100-year-old iron railway bridge. After two years of operating with a temporary structure, the new bridge was finally installed at the site around 20 kilometers from Stuttgart at the beginning of September.

However, the large crane used for the initial work was no longer available to conclude the construction project. Like many other models of this crawler crane operated by European crane contractors, that LR 11000 is now in long term use for “Buckner Heavylift Cranes” at a major wind power project in the USA.

Wiesbauer, therefore, used a brand new 1,000-tonne crawler crane to remove the temporary bridge and install the final bridge structure and also for subsequent projects. Although the LR 11000 had plenty of space for its crane operations two years previously to hoist the historic bridge, the conditions on-site this time were significantly more restricted – there was very little space available for slewing operations, in particular, as a result of the assembly preparation areas for the new steel bridge and various prefabricated concrete components, containers and a great deal of other building material.

However, using the adjustable V-frame, crane operator Thomas Kley was able to adapt to the lack of space and effortlessly retracted the ballast pallet suspended from the derrick boom to a radius of 15 meters. After traveling around 20 meters on its crawler carriers, when the load was subsequently positioned with a radius of 61 meters, a total of 440 tonnes of suspended ballast was extended to a radius of 28 meters, in other words almost the maximum radius, using the V-frame.

“The V-frame with VarioTray, with its wide radius range from 13 to 30 meters, delivers massive benefits on sites like this, it saves time and also often dispenses with additional ballasting work during the job”,

explained Marco Wilhelm, Authorised Signatory, and Project Manager at Wiesbauer.

“The calculations and forecasts for the bridge weight changed constantly during this job. But this ballasting system enables us to react very flexibly when necessary. We had to do so several times on this site as a wide range of loads from ten to 185 tonnes had to be hoisted using a very wide range of radii over the six weeks that the job lasted. For example, due to a change in the design, the largest load that required hoisting was in fact a 185-tonne prefabricated concrete component.”

For the jobs in the wind farm, which followed the bridgework, the crawler crane was once again operated exclusively with the V-frame and the VarioTray detachable ballast pallet.

“We only need the full counterweight for erecting the crane. After that, we only use the undocked center section of the suspended ballast on the wind turbines.”

But Marco Wilhelm does not believe that the new crawler crane flagship of the Wiesbauer fleet will be restricted to wind power sites, he also thinks that the crane will be very useful for jobs in industry and bridge construction as well as large infrastructure projects. With around 80 cranes and a workforce of 160, Wiesbauer GmbH & Co.KG is a major provider of crane and heavy haulage logistics services based in southern Germany.

The integration of what is now the fourth generation of family members in the company provides consistency and continuity at Wiesbauer. The LTM 1750-9.1 mobile crane mentioned above was collected from Liebherr in Ehingen by the great-grandchildren of company founder Franz Wiesbauer.

This modern, power pack of a 9-axle crane is the third mobile crane of this type that Wiesbauer now has in its fleet.

“One of the main reasons behind our purchase was the increase in crane performance delivered by the new 800 tonne kit for this crane”,

explained the three young entrepreneurs. With a luffing jib and Y guying, the company now has a full set of equipment for the LTM 1750-9.1. The fact that it has the complete set makes this crane unique in Baden-Württemberg. In addition to the erection of tower segments at wind farm sites, the new crane will also be used for industrial installation work and jobs on the ”Filstal Bridge” project between Stuttgart and Ulm.

Liebherr-MCCtec Rostock GmbH together with Aibel AS has signed a contract for the delivery of a cylinder-luffing crane, type RL 2600-35 Lit. The company TenneT TSO GmbH commissioned Aibel AS to build the offshore platform DolWin epsilon on which the Liebherr crane will be used for supply and maintenance tasks on the German North Sea.

The RL 2600-35 Lit is a weight-optimized and compact designed offshore crane. It is the ideal equipment for small platforms, where space is limited. The RL 2600-35 Lit has a box boom with a maximum working outreach of 52 meters and a maximum lifting capacity of 35 tons.

“With the RL 2600-35 Lit, we are delivering the latest innovation within our offshore crane portfolio. The crane is ready to be equipped with innovative maintenance features to meet the demanding requirements of normally unmanned offshore platforms and with its reliable and maintenance-friendly design the RL 2600-35 Lit will help to lead the DolWin5 project to a success”,

says Matti Basan, Sales Manager Offshore Cranes.

With DolWin5 TenneT realizes a high-voltage direct current offshore grid connection system in the German part of the North Sea. The grid connection has a transmission capacity of 900 MW and is located in the DolWin cluster. DolWin5 is to connect the offshore wind park Borkum Riffgrund 3 to the high-voltage grid onshore.

Long cooperation with Aibel AS and TenneT

The RL 2600 will be delivered in the middle of 2021. Until that, Liebherr will collaborate closely with Aibel AS, who is responsible for building the offshore platform. With this order, the business relationship between Liebherr and Aibel AS is expanded and strengthened. Once the platform has been completed, TenneT will take it over and operate the RL 2600-35 for maintenance work and the loading and uploading of offshore supply vessels.

Liebherr delivered already 13 RL cranes to the customer TenneT. Various sizes were requested, from the RL 850 and the RL 1500 to the RL 2650 with a possible maximum lifting capacity up to 60 tonnes. All of these cranes are placed on offshore platforms, which are necessary for the operation of offshore wind farms. Liebherr and TenneT are thus contributing to the expansion of renewable energies and emission-free power supply.

Weight-optimized and compact design

A weight-optimized and compact design with a load-bearing capacity up to 100 tonnes makes the ram luffing crane series (RL) from Liebherr an ideal piece of equipment for small and unmanned platforms or floating storage vessels. The ram luffing crane RL can be powered electro-hydraulically or diesel-hydraulically and is available for explosive areas in accordance with the requisite classification. The box-type booms in the RL crane have a cylinder luffing design. This lowers the height and weight to a minimum and enables low-maintenance operation.

Crane and heavy haulage contractor MaxiKraft has placed an order with Liebherr for lattice boom cranes for industrial and wind power jobs – the order for LR 1800-1.0 and LR 11000 crawler cranes and the LG 1750 lattice boom mobile crane is the largest single order for lattice boom cranes that Liebherr has ever received from within Germany. It is part of the total volume of around 40 million euros which MaxiKraft is investing in mobile and crawler cranes this year from Liebherr. For its part, Liebherr has taken a large parcel of used cranes in part exchange.

Maik Kanitzky, the owner of the group of companies, said:

“Wind power is on an upward trend in Germany and we want to be right at the forefront of it. That is why we are investing in the highest performance cranes with the latest technology which is currently available on the market”.

MaxiKraft ordered the LG 1750 with the SX3 system. This is the most powerful wind power boom available for the 750-tonne lattice crane. For the LR 1800-1.0, the company has ensured that it is suitable for universal, flexible use:

“We have bought the 800-tonne crane with a complete set of equipment – with a luffing jib for industrial jobs and a special boom for wind power. The LR 1800-1.0 is a very efficient machine for all sectors with an extremely impressive overall design”,

said Kanitzky. MaxiKraft ordered the LR 11000 with the latest system for erecting wind turbines, currently the most powerful available on the market.

Over the years, MaxiKraft has purchased a grand total of 660 mobile and crawler cranes from Liebherr, representing a total investment of half a billion euros.

“Continuous new investments are very important to us to ensure that we keep our crane fleet up with the state of the art”,

noted Kanitzky.

The MaxiKraft Group orders around 30 to 50 new cranes every year. The current order for 2020 comprises 31 mobile cranes and, in addition to the three lattice boom cranes, covers the whole range of crane models from 2 to 9 axles.

MaxiKraft was founded in 1992 by Maik Kanitzky as a one-man company. Its successful growth is reflected in its figures: Today, with its subsidiaries MaxiMum, Kranlogistik Sachsen, Treffler, and Kranlogistik Lausitz the group has a total of 500 employees at 23 sites. The company specializes in all work requiring mobile and crawler cranes, as well as heavy haulage. Around 80 percent of its fleet is made up of Liebherr machines.
