Abstract
The disclosed embodiments provide a drilling rig having a tubular delivery arm that vertically translates the mast in a non-conflicting path with a retractable top drive. The retractable top drive translates a well center path and a rearward retracted path. The tubular delivery arm is operable to deliver tubular stands between a catwalk, stand hand-off, mousehole, and well center positions. An upper racking mechanism moves tubular stands between a racked position of the racking module and a stand hand-off position between the mast and racking module. A lower racking mechanism controls the movement of the lower end of the tubular stand being moved coincident to the movements of the upper racking mechanism. An upper support constraint stabilizes tubular stands at the stand hand-off position. A lower stabilizing arm guides the lower end of tubular stands between the catwalk, stand hand-off, mousehole, and well center positions.
