ABSTRACT:
An adapter on the nose of a pneumatic ram engages the end of an underground pipe and under the action of the ram drives the pipe ahead of it for removal. The adapter has a frusto-conical channel at the larger diameter end of a frusto-conical region of a nose section for receiving the end of a pipe upon radial expansion of the pipe end to thereby secure the adapter to the pipe while preventing excessive radial expansion of the pipe end.
