Abstract
A pipe handling assembly carried by a horizontal boring machine includes a pipe box having a plurality of columns. One or more pipe sections may be received and stored in any of the columns. A pair of shuttle arms are used to move the pipe sections from the pipe box to a carriage included in the machine. The pipe column selection assembly includes an elongate rotatable shaft that carries a series of stop elements. A shaft-mounted pinion gear drives movement of the shuttle arms. A longitudinally positionable bolt element can block the rotational path of any selected one of the stop elements. Such blockage stops movement of the shuttle arms beneath a corresponding one of the columns. The pipe column selection assembly allows an operator to select which column to load or unload a pipe section into and from within a pipe box.
