Keyfacts
  • Foundation block 1.200 t

Background

Indirect vibration isolation of a machine or an installation increases the inherent rigidity and results in a significant improvement of the dynamic behaviour with large load changes and displacement paths.
For the exact design of the foundation, the characteristics of the machine must be considered. Only then can a cost-effective solution for the long-term and disruption-free operation of the installation be guaranteed.

Task

With certain applications the inclusion of steel construction or cast-iron plates is not sufficient. In this case, we developed a foundation solution for receiver isolation of a milling mechanism opposite the press plant area for an automotive plant.

Solution

We installed a foundation insulation with isolation pad sets and lost formwork. Isolation pad sets are optimally suited for vibration insulation of foundations. With additional mass and lowering of the centre of gravity, the insulation efficiency was improved and the vibration amplitude reduced. In doing this, we achieved the isolation and decoupling of the milling machine with the foundation from the construction ground and could thereby guarantee disruption-free operation.
