ABSTRACT:
An improved pipe-moving apparatus is disclosed having a pipe-insertable elongate member which is articulated for ease of use, particularly for pipe laying near trench ends. In a preferred form, the elongate member has a series of at least two carrier members pivotably interconnected end-to-end, with the proximal end of such series of carrier members attached to the controlling mechanism, and structure supporting the carrier members in alignment when the carrier member series is suspended by its proximal end. A highly preferred embodiment accommodates the removable insertion of one or more additional carrier members in the series to extend the length of the elongate member.
