ABSTRACT:
A pipe-handling apparatus for moving a pipe to and from a drilling floor of a drilling rig includes a main support structure, a ramp extendable between the main support structure and the drilling floor, a pipe carrier mounted on the main support structure for moving relative thereto between a lower position and an elevated position over the ramp, the carrier including a ramp end adjacent the ramp, an far end, and an elongate indentation on its upper surface to accommodate a pipe therein, a lift arm including a first end and a second end, the lift arm being pivotally connected at its first end adjacent the far end of the carrier and operable below the carrier to lift and support the carrier's far end to an elevated position, a track on the main support structure for supporting axial sliding motion of the carrier and the lift arm therealong, the track including a stop for limiting axial movement of the second end of the lift arm along the track toward the ramp, and a drive system for pulling the carrier from the lower position to ride along the ramp to an elevated position, the drive system capable of pulling the lift arm along the track until it is stopped against the stop in track and to continue pulling to cause the lift arm to be pivoted up about the stop to lift the far end of the carrier.
