Abstract
A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end. The dolly vertically translates the front side of the mast in response to actuation of a hoist at the crown of the mast. The tubular delivery arm translates the mast in non-conflicting passage of a top drive connected to the same mast, for positioning a tubular stand over the centerline of the wellbore, a mousehole, or a stand hand-off position.
