  • Apparatus and method for handling pipe sections
    Patent number: 7537424
    Abstract: An apparatus and method for handling pipe sections, preferably for use with a drilling head. The apparatus includes a storage bin defining a substantially fixed bin dispensing position, a transfer device for individually transferring a pipe section between the bin dispensing position and a pipe transfer position, and a handling device for individually moving the pipe section between the pipe transfer position and a drilling head interface position. The method includes presenting a pipe section to the bin dispensing position, moving the transfer device to the bin dispensing position to engage the pipe section at the bin dispensing position, transferring the pipe section with the transfer device from the bin dispensing position to the pipe transfer position, engaging the pipe section with the handling device at the pipe transfer position, and moving the pipe section with the handling device from the pipe transfer position to the drilling head interface position.
