Liebherr-Werk Nenzing GmbH, Nenzing, Austria, has been awarded the State Prize Clean Technology Austria 2012 for Liebherr’s development of the first hydraulic hybrid drive for cranes and construction machinery.
Awarded every second year, the State Prize is given jointly by three Austrian ministries. This year, more than 200 projects were entered in the competition. That’s more than double the number entered in 2010. The best entries in each category were honored with a State Prize.
Liebherr-Werk Nenzing, a world leader in the mobile harbor crane sector, convinced the jury with the increased handling performance and reduced fuel consumption provided Pactronic—the first hydraulic hybrid drive for cranes and construction machinery.
Pactronic uses a secondary energy storage device (accumulator) that is charged by regenerating the reverse power while lowering the load and using the surplus power of the primary energy source.
Minister for Economic Affairs Reinhold Mitterlehner presented the prize and emphasized: “Having built up its know-how for many years, Liebherr has now converted it into a ground-breaking innovation so setting new standards especially in energy efficiency. Eco-innovations safeguard qualified jobs, make Austria more competitive on the international market, and are a key factor for achieving energy and climate objectives,” says Mitterlehner.
Liebherr-Werk Nenzing GmbH ranks among the most innovative companies in its line of business and is considered the technology leader on the world market for maritime cranes and cargo handling equipment. The focus is laid on innovations in the fields of drive technology and electronics development.
