The Liebherr LS Series is a range of heavy-lift ship cranes developed and manufactured by Liebherr as part of its maritime crane portfolio.
The LS series is designed for installation on multipurpose vessels, heavy-lift ships and offshore support vessels. Depending on configuration, LS cranes are capable of handling heavy offshore components, container handling, and bulk cargo.
History Liebherr Group began manufacturing ship cranes in 1958, when it delivered its first ship crane (type B36, approximately 3 tonnes lifting capacity).
The LS series was introduced in response to the growing demand for heavy cargo handling on board vessels.
Design and engineering The cranes are mounted on a slewing ring and pedestal structure integrated into the vessel's deck. Power supply can be provided by the ship's electrical system or by dedicated generator units, depending on vessel configuration.
Structural design
LS cranes are constructed with a pedestal, slewing platform, machinery house, and a box-type jib. The jib structure is typically of welded steel construction. The pedestal transfers loads from the crane into the vessel's hull structure.
Representative models and technical data
The LS series includes models with different lifting capacities and outreach lengths.The lifting capacity generally exceeds per crane. In tandem operation, two or more cranes work together to lift a load that exceeds the SWL of a single crane.
Model Maximum lifting capacity Typical outreach LS 150 LS 250 LS 500 E LS 800 E
