State-of-the-art work equipment – such as professional simulation tools – is an essential ingredient of WIRTGEN’s standard tools of the trade. It forms an integral part of the highly complex engineering process to determine the ideal solution. A prime example of this is the holder base. In combination with the selected alloy, its defined geometry results in high wear resistance, the best possible weldability and even load distribution, thus offering reliable protection against excessive loading of the holder base. High shear forces, in particular, are deflected most efficiently in this way.
