ABSTRACT:
A first portion of the device is suspended by a head from the mounting for an excavator bucket and comprises a first jaw and a guideway. A second portion of the device comprises a second jaw and a slide slidable within the guideway under the control of a hydraulically operated ram. Pins extend from the upper end of the second jaw and can extend through respective holes in sheeting held between the jaws and into respective holes in the upper end of the first jaw. Opposing plates are resiliently mounted on the respective jaws for engagement with the opposite sides of the sheeting. Vibratory means mounted on the second jaw vibrates the plate and thus the other plate and the sheeting therebetween.
