100% electric crane

Euroports Germany will expand the capacity of its bulk terminal at the Rostock Overseas Port with Liebherr’s 100% electric LPS 420 E portal crane, to be delivered in summer 2022.

Karsten Lentz, managing director of the Euroports Germany Group, said: “We have opted for a fully electric crane, the LPS 420 E. In future, the crane will be used to handle all types of goods at this terminal. In addition to building materials, this also includes ores, lime, gypsum, wood chips and many more.”

124t max lifting capacity

This all-electric gantry crane is designed for ports and terminals with electric infrastructure. All crane movements such as luffing, lifting, slewing and travelling movements are carried out by means of emission-free electric motors.

The LPS 420 E has an outreach of up to 48m and a maximum lifting capacity of up to 124t, ships 2/4 up to Post-Panamax class can be served. The main components of the electric drive are liquid-cooled and the heat is dissipated via heat exchangers mounted outside the crane. Externally mounted cooling units have the advantage, especially in bulk handling, that no air is brought into the interior of the crane. This keeps dust contamination to a minimum.

Thanks to the Liebherr active front-end frequency converter, deviations in the power supply can be easily compensated for safe and stable operation. The machine is equipped with high-performance power accumulators to reduce the peak load in the crane’s main power supply and to use regenerative energy within the system.

In addition, the synchronous electric motors have a low moment of inertia and provide fast response for precise driving characteristics.
