  • Pile driving apparatus and method
    Patent number: 5332047
    Abstract: A pile driving apparatus and method includes a hammer assembly having a guide member extending therefrom. The guide member is engageable with the pile, and the hammer is connected to the end of a crane line or the like. A retainer chain is interconnected between the hammer and the pile. The hammer is lifted and lowered in response to operation of the crane, and the retainer chain functions to maintain the guide member in engagement with the pile during upward movement of the hammer. The pile thus functions to guide upward and downward movement of the hammer as it is raised and lowered in response to operation of the crane.
