Abstract: A slant-type drilling rig assembly is disclosed having a pipe handling device which requires one operator during the transfer of conduit sections between an inclined drilling mast and a generally vertical conduit storage structure. The pipe handling device, or transfer apparatus, includes a pair of support columns having a horizontal structure connecting the upper end portion thereof. Freely suspended below the horizontal structure are an operator control station and an elevator. The elevator is connected to a fluid pressure operated means for raising and lowering which means is in turn connected to a fluid pressure actuated slidably mounted carriage. The transfer apparatus is pivotally mounted at its lower end for arcuate movement in a plane between the drilling mast and the pipe storage structure.
