Liebherr has delivered its first mobile harbour crane that complies with the new EU Stage V emission standards.
The Liebherr LHM 420 mobile harbour crane was officially inaugurated in the middle of February at the port of Passau in Bavaria.
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. These regulations already applied to engines above 560 kW output, which are fitted to all Liebherr MHCs from the 420 upwards.
“Only minor technical adjustments were made to achieve the new emission standard,” the company stated. “The atomisation of the AdBlue urea now takes place through an improved air-assisted injection. This significantly improved the degree of atomisation and increased effectiveness. In addition, a corresponding new control unit was installed.”
For its European customers, all Liebherr had to do was atomise the AdBlue through an improved air-assisted injection. In addition, a corresponding new control unit was installed.
Stage V does not set a particle count limit for > 560 kW engines, so there is no need for Liebherr to fit a DPF.
The LHM 420 sits in the middle of Liebherr’s mobile harbour crane product range, with a maximum capacity of 124t. It can be used for a wide range of applications including bulk handling, general cargo and container lifts. Bayernhafen Passau will also use the new crane for handling complete wind turbines.
