Liebherr LS Series Ship Cranes
The LS series offers high performance heavy-lifting solutions ✔️ with low self-weight, small footprint ✔️ and superior control system Litronic The LS series offers high performance heavy-lifting solutions. With capacities ranging from 120-1000 tonnes, LS cranes cover the main areas of the heavy cargo segment. With its compact design the LS series stands for simplified interfaces and easy vessel integration. LS cranes are distinguished by their superior control system – Litronic. Thanks to this intelligent software LS cranes always achieve the maximum speed (depending on the respective load) and full utilization of the load moment. Furthermore, LS cranes feature state-of-the-art assist systems and are prepared for future applications. Take a look at the electrically driven heavy-lift crane - the flexible problem solver.
