Large spring elements are used for vibration-isolated mounting of heavy machinery, such as turbines, large blowers, or mechanical or hydraulic presses. Viscoelastic dampers are integrated into the production series in areas prone to earthquakes. The spring characteristics are tested and determined by our pre-load tester. Assembly is usually performed in two steps: the elements are placed after the bare brickwork is finished; releasing and alignment of the elements are done after the turbines are mounted.
