Apparatus that mounts on a standard construction vehicle, such as a crawler or a backhoe. The apparatus drives piles, including sheet piles, that typically are used for bulkheading and earth fortification. A hydraulic cylinder with a downward extendable piston is fixed on a leader and the hydraulic pressure drives the piles. The apparatus is self-erecting and transportable on the construction vehicle.
