Abstract: A handling assembly for pipe sections for a horizontal directional drill includes a thrust frame and a pipe handler assembly track that is attached to the thrust frame so as to define a pipe section transfer location. The handling assembly also includes a pipe handler carrier that is mounted on the pipe handler assembly track and a magazine that is mounted adjacent to the pipe handler carrier and adapted to discharge a pipe section from the bottom of a selected column to the pipe section transfer location. The pipe handler carrier may be moved along the pipe handler assembly track to a plurality of positions in each of which a pipe section at the bottom of a column of the magazine is aligned with the transfer location, and a column selector rod is mounted with respect to the thrust frame so as to selectively locate the pipe handler carrier along the pipe handler assembly track at a position to align a column of the magazine with the pipe section transfer location.

Abstract: An auger boring machine having a drive mechanism for moving the machine along a desired direction of travel includes a drive motor having a shaft and a pinion mounted on the shaft. A method for manufacturing a track for such a boring machine includes providing a track base rail adapted to support the auger boring machine and arranging the base rail along the desired direction of travel of the boring machine. The method also includes cutting a gear rack which includes a plurality of gear teeth along one side that are adapted to mesh with the pinion of the drive mechanism, and a flexibility notch on the side opposite the gear teeth. The gear rack is attached to the base rail with the gear teeth oriented so as to engage with the pinion of the drive mechanism.
