Background History

Hans Liebherr founded Hans Liebherr Maschinenfabrik (engineering works) in an effort to help rebuilt the country he loved. Making everything from refrigerators to hydraulic excavators Liebherr has a wide variety of products. After finding a hole in the market for high-quality cranes, Liebherr decided to fill the gap.
