Structure and principle 

•Produce vibrating force via rotation of eccentric wheel

•Eliminate the vertical vibration via operation of symmetrical eccentric wheel and only keep the horizontal thrust

•Adjust the vibration amplitude by adjusting the phase difference of the horizontal eccentric wheel set

•Adjust the vibration frequency by adjusting the rotational frequency of the eccentric wheel set

•Minimize the counterforce of the motion system with precise hydrostatic guideway system

•No counterforce is applied upon the installation foundation, which should only bear the weight of vibration machine.
