The world's biggest trade fair for construction machines, the Bauma, is now on in Munich. Among the exhibitors is Liebherr. Expected are a good half a million visitors from the trade - and, of course, brisk sales of construction machines. Liebherr operates in 17 countries on four continents and has annual sales of more than nine billion euros. Report by Christian Pricelius.
