OSCILLATOR PILES

Franki’s large diameter ‘oscillator’ pile is one of the most versatile pile types ideal for heavily loaded structures in adverse soil conditions.

This pile type is used where there is a need to transfer loads to great depths through boulders and rock layers generally below the water table.  These attributes make it ideal for river bridges and marine structures. Franki has upgraded its capacity and capability to install oscillator piles through the purchase of two large piling rigs with the latest oscillator attachments.
