ABSTRACT:
An apparatus and method for continuously preloading during installation and removal of steel sheet piles, steel pilings, and casing piles, with a telescoping, articulated boom having a free end for creating the downward driving force, a weighted base to provide support and stability for the boom, a connector at the free end of said boom to engage the piling, a modified resonance-free vibratory hammer, to allow for simultaneously vibrating the piling while applying to the piling the continuous downward or upward force.
