Jürgen Wirtgen and Stefan Wirtgen took over the management of the company in 1997. What had been a vision for Reinhard Wirtgen now became reality under his sons: by combining the three strong WIRTGEN, VÖGELE and HAMM brands, they succeeded in offering customers the full range of mobile machines for road construction.
Developing WIRTGEN into a corporate group began with the successful integration of VÖGELE, the road paver manufacturer based in Mannheim. HAMM, the renowned roller manufacturer based in the Upper Palatinate town of Tirschenreuth, was integrated into the WIRTGEN GROUP in 1999. Expanding the sales network by setting up fully owned subsidiaries created a strong presence for the corporate group on a global scale. Production capacities and efficiency were increased at the same time by making high investments in the three main production plants in Windhagen, Mannheim and Tirschenreuth.
