ABSTRACT OF THE DISCLOSURE Pipe handling systems are generally somewhat bulky, relying on a plurality of hydraulic cylinders and complicated linkages. A relatively simple, compact pipe handling apparatus for use on a derrick of the type which can be rotated between the horizontal and the vertical includes an elongated track for mounting on one side of the derrick, a carriage slidably mounted on the track, three swing arms connected end to end, the first arm being connected to a rotary actuator mounted on the carriage, rotation around an axis perpendicular to the longitudinal axis of the derrick, a second rotary actuator between the first and second swing arms for rotating the second and third swing arms around an axis parallel to and spaced apart from the longitudinal axis of the derrick, a third rotary actuator for rotating the third swing arm, which carries a pair of jaw assemblies. Thus, the apparatus can be used to grip a pipe section, move the pipe section up an inclined or vertical derrick, rotate the pipe section into a first position parallel to the longitudinal axis of the derrick and then into alignment with an existing pipe string in the centre of the derrick, and lower the pipe section into engagement with the existing pipe string for attachment thereto using a conventional top drive.
