Claim Text:
1. A method of pipe make up, comprising: attaching a pipe handling attachment to a first end of an arm of a prime mover so that the pipe handling attachment is adjustable relative to the arm about three axes that are perpendicular to one another, a second end of the arm is attached to the prime mover, the pipe handling attachment includes a pipe break mechanism and at least one pipe roller gripping assembly each of which is mounted on a main beam, the main beam is tiltable about one of said three axes, and a tilt actuator connected to the main beam that provides a force to tilt the main beam; using the pipe handling attachment to pick up a first pipe at a first location, the first pipe having first and second threaded ends; using the prime mover and the pipe handling attachment to move the first pipe to a second location with the first end of the first pipe adjacent to an end of a second pipe to which the first end of the first pipe is to be attached, the end of the second pipe is threaded for attachment to the first end of the first pipe; using the prime mover and/or the pipe handling attachment to align the first end of the first pipe with the end of the second pipe; using the at least one pipe roller gripping assembly to spin the first pipe relative to the second pipe to thread the first end of the first pipe onto the end of the second pipe; and after the first end of the first pipe is threaded onto the end of the second pipe, using the pipe break mechanism to apply final torque to a predetermined torque value to a joint between the first end of the first pipe and the end of the second pipe.
