摘要： A tailing arm and tubular positioning device with an arm base unit, control module and an arm engaging a hydraulic power unit. A side shift assembly attaches to an opposite end of the arm and fluidly connects to the hydraulic power unit. A lower roller assembly secured to the side shift assembly and fluidly connected to the hydraulic power unit and an upper roller assembly engages the hydraulic power unit. The control module is configured to move upper and lower rollers to support a tubular and maintain contact with the tubular through a range of motion of the tubular, position the upper and lower rollers symmetrically and in snug contact with the tubular, shift the tubular longitudinally with the upper and lower rollers using roller cylinders and rotation of the arm, shift the tubular laterally with the side shifting assembly, and release the tubular.
