Liebherr delivers worm-driven slewing drive solution

The company claims the worm-driven slewing drive units are currently the largest in the world. eConowind’s Ventifoil towers can reach up to 40 metres high, supplying propulsion support for cargo ships. Liebherr’s slewing drive units turn these huge sails.

Liebherr slewing drive units are self-contained systems consisting of a drive and a bearing unit. This makes the components particularly resistant to extreme environmental influences, such as salt water or dust. Special sealing systems and surface coatings also add to the high resistance of the large components and make them ideal for use at sea. The massive, worm-driven components from Liebherr measure 1.720 mm in diameter each and weigh together over 1.4 tonnes.

“With the delivery of the huge slewing drives, Liebherr does not only set a new record, but also makes a decisive contribution to more sustainable shipping and a low-emission world,” concludes Benjamin Schmid, Key Account Manager Maritime Applications at Liebherr-Components AG.
