ABSTRACT:
An electromagnetic pile driver has an elongated guide in which a magnetic core is permitted to fall by gravity to impact against an anvil transmitting the impact energy to the pile. The core is raised by a coil in a ferromagnetic sheath disposed at an upper portion of the guide and an upper anvil can be provided and coupled to the pile when the apparatus is used for withdrawing piling. The coil is energized by the control discharge of a capacitor.
