Liebherr has supplied its first mobile harbour crane that meets the new EU Stage V emission standards. The customer is Bayernhafen GmbH & Co KG, the location is the port of Passau on the River Danube and the crane is a LHM 420 mobile crane, with a maximum lift capacity under hook of 120 tons
The crane will be used to handle breakbulk general cargo, containers, bulk cargo and project cargoes, including wind farm components.
Joachim Zimmermann, the port’s managing director, said: “We are strengthening our position in the heavy lift segment with this new investment."
Although the previous crane was able to handle relatively light wind blades, the new crane will be used for the heavy towers and aggregates with unit weights of up to 100 tonnes.
Mobile crane manufacturers have a transition phase of up to three years to adapt the conversion of exhaust gas purification to EU Stage V. The emission limits are the same as US EPA Tier 4. The US regulations already applied to engines above 560 kW output, which are fitted to all Liebherr MHCs from the 420 upwards.
For its European customers, Liebherr said that all it had to do was atomise the AdBlue through an improved air-assisted injection. In addition, a corresponding new control unit was installed.
Although Stage V regulates > 560 kW engines for the first time in the history of EU emissions controls, it does not set a particle count limit for them (mandatory under Stage V for
< 560 kW). This means that Liebherr does not have to fit a DPF to engines in its 420, 550, 600 and 800 MHCs.
