Last month Liebherr-Werk Nenzing GmbH celebrated its 35th anniversary. An open day with over 20,000 visitors concluded the festivities in the Austrian village of Nenzing. Such a high attendance by far exceeded the ambitious expectations in the planning stages. The festivities started on Wednesday, 28th September, and on the second day Liebherr-Werk Nenzing GmbH welcomed around 500 customers from all over the world. The open day was a showcase of the Nenzing factory, with company tours, machinery presentations, multi-vision shows, and information booths.
The company tour led through all production facilities and offered the guests an insight into production technologies such as fully automated robot manufacturing in the new workshop building VIII. Moreover, the visitors had the opportunity to get a close look at large-dimensioned machines such as mobile harbor cranes or offshore cranes. On the test stand product presentations demonstrated how mobile harbor cranes weighing up to 600 tons handle containers or move heavy loads in tandem operation with utmost precision.
One of the highlights was the presentation of the first hydraulic hybrid drive Pactronic for mobile harbor cranes, providing an increase in turnover combined with reduced fuel consumption. This innovative drive system and its positive effects on the working speed were impressively demonstrated on the prototype of the new mobile harbor crane LHM 420. Another innovation introduced for the offshore industry was the Active Heave Compensation (AHC) system, which registers the strength of wave movement and accurately aligns the suspended load. As an example for new developments in the field of materials technology the new crawler crane pendant straps made of carbon fiber were exhibited. The special properties of carbon fiber and its relative lightness offer a huge potential for technical progress.
