First exhaust gas purification stage V crane

With a maximum capacity of 124t, the Liebherr LHM 420 can be used for a wide range of applications like bulk goods, general cargo or container handling. bayernhafen Passau, part of port operator bayernhafen, will also use the new crane for handling complete wind turbines.

“Although the previous crane was able to handle the relatively light wind blades, the new crane will be used for the heavy towers and aggregates with unit weights of up to 100 tonnes,” said Liebherr.

Early compliance

Before the legislation came into force in 2019, Liebherr delivered the first unit with the new EU emissions standard V to the Port of Passau – at the end of 2018.

Liebherr Mobile Harbour Cranes are equipped as standard with the new exhaust gas cleaning system, if required in the respective country of destination.

Only minor technical adjustments were made to achieve the new emission standard, said Liebherr.

The atomization of the adBlue urea now takes place through an improved air-assisted injection. This significantly improved the degree of atomisation and also increased effectiveness. In addition, a corresponding new control unit was installed.

Manufacturers will receive a transition phase of up to three years to adapt the conversion of exhaust gas purification to the new Tier 4 final stage 5.
