ABSTRACT:
A pipe manipulator for dismantling a pipeline includes a frame, a slide, a plurality of jaws for gripping the pipe to be dismantled, disengaging means, means for connecting the slide to the jaws and telescoping means. The telescoping means is connected to the disengaging means and the slide. Movement of the telescoping means causes movement of the slide and the disengaging means. The slide and jaws are mounted to the frame such that the slide moves in a longitudinal direction, opening and closing the jaws. The pipe can be uncoupled, dismantled and relocated without excessive damage to the pipes such that the operation is economically feasible.
