According to the company, the LHM 420 sets new standards for large handling equipment: the unique cruciform undercarriage system for example, “is unrivalled in terms of stability and operational safety” and the utilisation of the tubular, lightweight tower design reduces corner loads by 12% compared to the LHM 400.
The LHM 420 is the second product to be equipped with Liebherr’s new Pactronic® hybrid drive system and follows the LHM 550 which was introduced in 2010.
Liebherr points out that apart from its environmental advantages, the Liebherr Pactronic® also increases handling performance: hoisting power for example, is doubled resulting in hoisting and lowering speeds also increasing by up to 100%. In terms of productivity, a machine equipped with Pactronic handles the same quantity of cargo in 30% less time compared to a conventional machine with an equal power rating of the primary energy source.
