Vibratory pile driving apparatus
The present invention relates to a vibratory pile driving apparatus for upending a pile and for driving a pile into the ground and/or extracting a pile out of the ground. The apparatus comprises a frame element, a clamping device, attached to the frame element at a first side thereof and configured to clamp the pile, at least one vibrator device, attached to the frame element at a second side, opposite to the first side, and configured to subject the frame element and the clamping device to a vibratory load, and a lifting yoke, rotatably connected to the frame element. The pile driving apparatus is configured to be suspended from a crane by the lifting yoke during use and the lifting yoke is configured to be rotated relative to the frame element to move the pile driving apparatus between a loading configuration and a pile driving configuration. The lifting yoke comprises one or more dampening elements, which are, during use, configured to deform to inhibit transmission of vibrations to the crane.
