ABSTRACT:
An apparatus for attaching a caisson to a device for inserting and/or extracting the caisson. The apparatus comprises three beams. A first beam is relatively long and is normally connected to a vibratory device such that its longitudinal axis is orthogonal to the lengthwise axis of the vibratory device. The second and third beams are relatively short and are connected to the vibratory device such their longitudinal axes are parallel to the lengthwise axis of the vibratory device. Four clamps are mounted on the beams to fix the beams onto the caisson. A flange on the first beam is widened at least a middle portion thereof to stiffen the beam and allow the beam to be securely connected to the vibratory device. The first beam may also be used with its longitudinal axis parallel to the lengthwise axis of the vibratory device.
