May 7 - In a bid to tackle emission and fuel consumption targets, Liebherr has introduced a new range of diesel engines for its mobile harbour crane fleet.
The smaller crane models - LHM 120, LHM 180 and LHM 280 - will be equipped with a stage IV / tier 4final 400 kW engine. The larger crane models - LHM 420, LHM 550, LHM 600 and the new giant LHM 800 - will be available with a stage IV / tier 4final 725 kW diesel engine. Both diesel engine versions can be boosted with a Pactronic hybrid drive system for up to 100 percent extra power.
The new engines will be essential to meet the latest European Union emission standard stage IV and Tier 4final of the US Environmental Protection Agency (EPA).
Globally, an increasing number of ports are focussing on environmental issues, said Liebherr. The new engines will provide greater fuel efficiency, require less energy for engine cooling and less exhaust backpressure, which preserves the engine components.
