ABSTRACT:
For laying and joining successive sections of pipe, a vehicle is movable over a course along which the pipe is to be laid. Carried on the vehicle is a crane, the outer end portion of which is movable both vertically and horizontally relative to the course of the pipeline. A controllable grapple mounted on that outer end of the crane is engageable with a section of the pipe, so that operation of the grapple together with the crane enables each section of the pipe to be picked up, moved into position over and deposited along the course. A vibrator is attached to the grapple and serves to induce vibration thereinto and from the grapple into the section of pipe being carried. The vibration is induced as an end of the section carried by the grapple is slidably mated with another section of the pipe which lies along the course. The vibration also is used to assist in bedding the pipe section being laid.
