New all-electric heavy lift ship crane

By Niamh Marriott18 August 2022

Liebherr is expanding its heavy lift crane series with an 800 tonne capacity crane, for work with large offshore wind industry components.

The manufacturer said the crane is fully electrically powered, enabling a reduction of CO2 emissions on heavy lift vessels.

The growth of wind turbines is leading to increasingly heavy individual component weights, the company claimed. In addition, the handling of large components requires a longer outreach of the cranes used currently.

The company said it designed the crane as the supply of heavy lift vessels with cranes offering a maximum lifting capacity of 800 tonnes is lower than the expected future demand. It expects a growth in the crane segment market.

“The new cranes follow on from a long tradition and decades of experience in building ship cranes. The push into the 800 tonnes size segment does not represent new territory - Liebherr has already supplied onshore and offshore cranes in the 3000-5000 tonnes category,” said Gregor Levold, sales director for Liebherr offshore, ship and port cranes.

All-electric

The LS 800 E is an all-electric drive concept and all sections of the crane will be electrically driven.

“We have many years of experience with all-electric drives from the port equipment sector, among others. The development of the crane is done completely in-house. We can also cover the procurement of individual components largely in-house at Liebherr,” said Levold.

All drive components are installed inside the crane, which Liebherr said facilitates the integration of the crane into the ship’s design, making space more efficient.

Its “Master V” control unit offers fast data processing and enables the integration of future assistance systems and semiautomated process applications, which can save time and ensure worker safety.

New design

The exterior design of the crane has been renewed. The crane is factory coloured in white and grey and the designation of the crane is on the tower.

The designation of the Liebherr ship cranes has also been adjusted. Instead of the previous CBB crane designation, the cranes will in future be called LS. The new terms and the capital letters used allow a direct assignment as Liebherr (L) - ship crane (S). The number, as part of the designation, provides information about the maximum load capacity, which is 800 tonnes for the LS 800 E. The E stands for the electric drive.
