Abstract: A pile driving apparatus including two vibratory hammer units fixed to the top of a support plate having a U-shaped cutout, and a pair of hydraulic clamps fixed to the bottom of the support plate. The support plate is secured to the pile when the hydraulic clamps on the bottom of the support plate engage flanges provided on a hydraulic pile clamp which is clamped to the pile. Hydraulic motors housed within the vibratory hammer units cause the pile to vibrate in a vertical direction, thus gradually driving the pile into the ground. The U-shaped cutout allows the support plate to be positioned on the pile, with the pile passing through the support plate, without having to lift the vibratory hammer and support plate assembly over the top of the pile. This arrangement is particularly advantageous in circumstances where overhanging structures limit the clearance available above the location of the pile.
