摘要：A machine for pipe maintenance, which travels forward through a pipeline andeffectively removes foreign substances sticking to the inside of a pipeline, using friction
members that are moved along the inside of the pipeline by a rotator assembly androtated by rotating shaft assemblies , which come in contact with the inside of thepipeline is disclosed. Further, rotating shaft assemblies and a rotator assembly arerespectively rotated by first and second rotating units , such that it is possible tomaximize the effect of removing foreign substances in the pipeline by smoothly rotatingthe friction members , and also improve durability by preventing an erroneous operationand damage due to load that is applied during the operation.
