• New Liebherr LHM 420 mobile harbour crane announced, bridging the gap between the LHM 550 and the LHM 280 cranes

• The official launch of the LHM 420 will be at the TOC Europe show in June

Liebherr has announced its latest model of mobile harbour crane - the LHM 420 - which will be officially launched in June at the TOC Europe 2011 show, Antwerp.

The new heavyweight crane is the successor of the LHM 400 and bridges the gap between the LHM 550 and the LHM 280.

The LHM 420 will be available in two variants with maximum lifting capacities of 84 and 124 metric tons. Maximum radius is 48 meters, making the LHM 420 ideal for loading and unloading from a wide variety of vessels, from Handysize to Post-Panamax class.

This crane is specially designed for container movement, bulk material, heavy loads and any other cargo handling tasks.

The LHM 420 crane retains the LHM harbour crane undercarriage system that has proved successful in previous models, making the crane highly manouevrable and unrivalled in terms of stability and operational safety.

The supporting system is also easily adapted to various sizes of support bases and pad sizes, and additional axle sets for better weight distribution are simple to incorporate.

The crane's tubular, lightweight tower design reduces corner loads by 12% compared to the LHM 400.

After the LHM 550, which was introduced in early 2010, the LHM 420 is the second product line serially equipped with the new Pactronic hybrid drive system.

Besides the well-known environmental advantages of hybrid drives, the benefit of the Liebherr Pactronic is increased handling performance.

Hoisting power is doubled, resulting in up to 100% higher hoisting and lowering speeds. In terms of turnover capacity, that means an increase of 30% compared to a conventional machine with equal power rating of the primary energy source.

In terms of annual turnover, a machine equipped with Pactronic handles the same quantity of cargo in 30% less the time. All running costs within the timeframe, which was gained by the quicker operation, are actual savings for the customer. Savings in energy costs, maintenance costs and labour costs are the most evident.

Docking time is reduced by 30%, making savings can also be made in laytime costs. As a bonus, vessels gain time to ship their scheduled routes, resulting in lower speeds and lower fuel consumption.

In addition, Pactronic leads to a reduction of exhaust emissions (CO₂) of 30%.
