  • Patent number: 7396060
    Abstract: A pipe pulling device secures to the end of a pipe, with wedge action, for pulling by equipment. The device has a shaft, a housing upon the shaft, one or more wedges, a cone, nuts, eye nuts, O rings, and a sleeve, all arranged coaxially. First the nut is placed upon the shaft, then the housing is oriented forward. The forward end of the housing has a beveled edge to assist in passage through soil. The contractor then places a wedge of three vanes upon the shaft within the housing. A hollow cone upon the shaft contacts the wedge. An eye nut then secures the assembled parts upon the shaft. In use, a contractor tightens the nut rearward thus pulling the cone forward and expanding the wedge. The Is wedge expands to grasp the pipe between the housing and the wedge. The contractor can then pull the pipe through soil.
