Abstract
A drilling apparatus including a magazine for holding a plurality of pipes, and a drive head is disclosed herein. The drive head includes a drive member adapted to be coupled to a pipe. The drive member is aligned along a drive axis. The drilling apparatus includes a first drive mechanism for rotating the drive member about the drive axis, and a second drive mechanism for moving the drive member axially along the drive axis. The drilling apparatus also includes a pipe transfer member for transferring pipes between the magazine and the drive head. The pipe transfer member defines a pipe receiving region for receiving a pipe. The pipe transfer member is movable between a first orientation in which the pipe receiving region is located under to the magazine, and a second orientation in which the pipe receiving region is located under the drive axis of the drive head.
