Abstract:
1. Apparatus for handling pipe comprising: an elongate frame structure for mounting on a ground surface; a carriage unit mounted on the frame structure selectively operable for reciprocal shifting along the frame structure; a boom member mounted on the carriage unit operable for selective pivotal movement relative to the carriage unit, in 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, the boom member being selectively adjustable, longitudinally, relative to the carriage unit so that the boom member may be pivoted at selected points along the length of the boom member; and an elongate pipe carrier mounted on the boom member dimensioned for receiving pipe so that the pipe's longitudinal axis is substantially parallel to the longitudinal axes of the boom member and the pipe carrier, wherein the pipe carrier is operable for selective pivotal movement about its longitudinal axis.
