Liebherr Unveils New Mobile Harbor Crane
Germany's Liebherr-Werk Nenzing GmbH has expanded its range of mobile harbor cranes, presenting its new model LHM 420 at the TOC Europe 2011 container handling trade show and conference. The 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 tonnes.
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. The crane is specially designed for container movement, bulk material, heavy loads and any other cargo handling tasks.
After the LHM 550, which was introduced in 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 improved hoisting and lowering with up to 100 percent higher speeds. In terms of turnover capacity, that means a gain of 30 percent compared to a conventional machine with equal power rating of the primary energy source, according to Liebherr.
"To master the years to come, our efforts will not only concentrate on making our cranes more economic and safer, but at the same time, we will implement sustainable concepts and ideas in close collaboration with our business partners to provide the technical solutions for the future," said Leopold Berthold, director of mobile harbour cranes/reachstackers, Liebherr-Werk Nenzing.
