ABSTRACT:
A foundation shock eliminator includes an upper block, a lower stationary base, an interconnecting assembly and an energy damping coating. The lower stationary base is mounted under the upper block. The interconnecting assembly is mounted between the upper block and the lower stationary base and includes an upper track, a lower track and a track joint. The upper and the lower tracks are respectively attached to the upper block and the lower stationary base and are arranged in a cross. The track joint is slidably mounted between the tracks. The energy damping coating mounted in the foundation shock eliminator absorbs shock energy. Consequently, the upper block will move relative to the lower stationary base to counterbalance the most horizontal shock effects and cooperates with the energy damping coating absorbing the shock energy in both horizontal and vertical directions so that reduction of shock is efficient.
