ABSTRACT:
An apparatus and method for handling pipe includes an elongate frame structure for mounting on a ground surface, in which a carriage unit is mounted on the frame structure and is operable for selective and reciprocal shifting along the frame structure. A boom member mounted on the carriage unit is operable for selected pivotal movement relative to the carriage unit, and a plane generally parallel to the boom member's longitudinal axis, about a generally horizontal pivot axis oriented transverse to the direction of shifting of the carriage unit along the frame structure. An elongate pipe carrier mounted on the boom member as dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axis of the boom member and the pipe member, wherein the pipe carrier is operable for selective pivotal movement about its longitudinal axis.
