Self Propelled Pipe Fusion Machine A self propelled enclosed apparatus for coupling sections of plastic pipe by fusion together to form a pipe line. The apparatus comprises a housing having a forwardly extending boom or trough for receiving pipe sections. Pipe sections are loaded onto the boom and fed to a fusion machine in the housing. The fusion machine is provided with hydraulically operated clamps and rollers to align and hold a section of pipe in mating relationship with a pipeline and a heating plate for forming a fused joint between the pipe section and the pipeline. Cooling apparatus is provided at the joint to reduce its temperature following fusion. Kick out rollers are provided, and the fused together pipeline exits the apparatus to a trailer towed thereby to be laid on the earth's surface or in trench. The trailer, self propelled apparatus, and boom are equipped with pipe support members to provide strain relief on the joint during fusion. The apparatus is self contained and all functions other than loading the pipe sections onto the forwardly extending boom are carried out within the machine by a driver operator. |
