Patent attributes
A pipe handling device and method for use with a horizontal directional drilling system. The pipe handling device stores sections of drill pipe in individual columns within a magazine. The magazine is constructed so that it can be mounted to a boring machine in a pin-up or pin-down orientation. A plurality of signal elements are attached to the magazine and each extend at least partially within a footprint of each column. The signal elements may move from a first position, indicating the column is full of pipe sections, to a second position, indicating the column is not full of pipe sections. A proximity sensor assembly detects movement of the individual signal elements and signals a processor accordingly. These signals indicate whether or not a given column is full of pipe sections.
