ABSTRACT:
Vibrational isolation is provided from the sonic energy employed to drive a piling or the like into the ground for the suspension and support system for the equipment, and for the power drive source for driving the sonic oscillators employed. A separate isolation system is provided for the support structure and for the power drive, each of these separate systems being optimized for the particular situation at hand. Thus, in providing vibrational isolation for the suspension and support mechanism, heavy large springs may be employed, capable of handling high loads, and having a relatively low spring rate to attain the desired isolation. On the other hand, the isolation system for the power drive employs relatively soft springs which effectively isolate the power drive from the vibrational excursions of the oscillator so as to avoid undue stress on the power drive, which might result in misalignment thereof, and damage to components of the power drive.
