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.
