Owing to high eccentric moments, the Vibration Generators can be equipped with large aux. tables, thus suiting them to transportation and seismic tests of large and heavy specimens. Also removing the aux. table or changing the aux. tables to smaller one enables relatively high-frequency and high-acceleration tests of small specimens
capable of exciting a specimen in two horizontal & vertical directions simultaneously as well as in each direction independently, thus suiting vibration tests of specimens, for which excitation in the Major Horizontal direction, either back & forth or right & left can precipitate over 90% of the hidden flaws detectable with excitation in the horizontal directions.
