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. During movement of pipe between the mast and the storage structure, the operator positioned in the operator control station is carried back and forth between the mast and the storage structure by the transfer appparatus so that the operator is available to perform such manual operations as may be necessary at both the mast and the storage structure.
