Abstract: A pipe hauling trailer is described for hauling and dispensing individual sections of elongated pipe for joining in end-to-end relation to form a pipeline. The trailer also includes structure for mounting pipe section end joining machinery, so the pipeline may be assembled directly from the trailer. The trailer includes racks for supporting the stack of pipe sections. Escapement cams are positioned at a bottom corner of the rack and are manually movable to engage individual pipe sections from the bottom of the stack, and to deliver the individual pipe sections to a dispensing station, where the pipe sections are supported by rollers for longitudinal movement rearward of the frame. A movable support is provided for a conventional pipe end joining machine on the trailer frame, so the successive pipe sections moving longitudinally from the frame may be joined end to end, thereby forming the pipeline directly from the present trailer.
