An apparatus for lifting and supporting a pile is provided. The apparatus includes a support structure coupled to the pile and a lifting device coupled to the support structure. Gripping plates of a lift head engage and lift the pile during extension of the lifting device. During retraction of the lifting device, gripping plates of a gravity vice engage the pile to support the pile in the lifted position. The extension and retraction of the lifting device is alternately repeated to lift the pile in steps to a desired height. |
