ABSTRACT:
A pile is lofted to a vertical position over a driving location. At a distance above its lower end the pile is embraced within a guide on an extensible rack on the crane chasis. Over the upper end of the pile a vertically elongate socket on the lower end of a hammer carriage is fitted, and driving ensues until the pile is self-sustaining, or until the hammer carriage nears the rack. Then the rack is disengaged from the pile and withdrawn, and driving is completed.
