The Dutch company Mammoet uses the LR for this special assignment. The crawler crane from Liebherr impresses beyond its enormous load capacities and high safety standards, through a quick and easy installation.
Equipped with the PowerBoom parallel boom system, the crane achieves stability. 13000
Thus, the load of the LR is increased by up to 50 percent. On the meter long Aeolus, a specialist vessel for the construction of offshore wind farms, four gigantic jack-up legs must be installed.
To meet this challenge, the Dutch heavy load and crane specialist Mammoet calls in the LR With a maximum lifting capacity 13000 3, tonnes, the LR is the world’s most powerful conventionally designed crawler crane. For the specialist application on the Lloyd shipyard in Bremerhaven, not only enormous load capacities are required; but the work must be carried out with extreme precision.
Once completed, the Aeolus is to be lifted high above the waves of the up to 45 metres deep water. As a gigantic jack-up platform, the specialist vessel works independently of any sea state. Along with the floating crane, the Matador 3, the LR lifts the mighty jack-up leg from the load barge.
Slowly, the Aeolus is hauled and the gigantic jack-up leg is manoeuvred between the ropes of the ship’s crane. The LR from Liebherr is not only impressive in terms of its performance. Crane operator Jouke Bruin on working with the LR Really nice to drive! To lift the mighty jack-up legs, the LR is equipped for the first time with the PowerBoom parallel boom system. Each of the so-called jack-up legs measures 87 metres, and weighs in at tonnes.
With PowerBoom the lattice boom extends over a length of 48 meters in parallel. Thanks to the fast set-up design of the LR and the support provided by Liebherr technicians, installation time is reduced to significantly less than the four weeks originally estimated. After just twelve days, the giant amongst the crawler cranes rises lift-ready meters into the sky. Once the crane system is in place, the powerful jack-up legs have to be installed into the large-sized hydraulic system of the installation vessel.
The technically most demanding lift takes place at the beginning of the job. The first stilt has to be pushed through the structure of the heavy-load crane on the Aeolus. The lift and subsequent installation of the the giant cylinder alone takes four hours. Along with the Matador 3 floating crane, the LR lifts the mighty steel pipe from the transport barge to align it vertically and transfer it fully.
With its 65 tonne hook block and fastening equipment, the crawler crane lifts a gross load of more than tonnes here, with a reach of 23 metres. With a maximum hook height of metres, lifting the jack-up leg over the high overhead cables of the ship’s crane is not possible.
Therefore, the steel cylinder is first swivelled on the ship’s deck.

With the aid of man-tall winches on deck, ljebherr Aeolus is slowly hauled. As the jack-up leg is directly over the opening, the complex insertion process begins: With large pulleys, the lliebherr is rotated into the correct position as it is lowered. The Mammoet team works around the clock on the Aeolus completion.
Each of the four lifts were prepared overnight, and where possible the load was attached ready. In daylight, the team, led by project manager Remco Zandstra, works on its individual installation tasks. After the four jack-up legs of Aeolus are installed, industrial divers affix the spud cans, also known as elephant feet.
These ensure that the Aeolus subsequently stands firmly on the seabed. Liebhherr just one week, all four jack-up legs of the specialist vessel are installed. An important reason behind the rapid success: Project Manager Zandstra adds: Close to 1, tonnes in just one lift: A load, liebher up till now required two crawler cranes, is mastered by the LR with PowerBoom alone.
Open video Close to 1, tonnes in just one lift: PowerBoom increases the load capacity of large crawler cranes by 50 percent liebhrr more.
The innovative technology also delivers excellent value for money. LR crawler cranes with lattice libeherr are in use all over the world. With load capacities up to 3, tonnes they can move very heavy loads safely and economically.
