To date no other equipment manufacturer has brought to market a machine capable of achieving resonant frequencies in a pile. Essentially it has been considered 'technically impossible', until now... Resonant frequencies are those that a solid body naturally assumes during relaxation from an energized state to an unenergized state. The lowest frequency at which a body freely vibrates is called the natural or fundamental frequency. Other resonant frequencies are called harmonics or overtones. A 'RTI' Resonant Driver can only be operated at the pile's natural or harmonic frequency. You'll need to forget alot of what is known about conventional vibratory pile driving when using a RTI Resonant Driver. It behaves & operates drastically different in a few areas. **Unlike conventional vibratory hammers, pile mass has no bearing when choosing the size of equipment needed for the job. The resonant hammer sees no pile mass when the pile is resonating. **The largest RTI Resonant Driver ever conceivable, could be used on micro piles. Unlike eccentric vibrators (where force cannot be modulated), all of RTI products adjust force independently of frequency. **There are no isolators between the hammer and the crane. They simply aren't needed. Because of this, there are no isolators to overheat when pulling on a pile. A ...
