    摘要： At one side of a transfer zone there are laterally spaced elongated members for supporting transversely thereof a plurality of parallel reclining pipestands. Means are provided for indexing the supporting members lengthwise across the transfer zone. At the transfer zone there are means for lifting each successive pipestand from the supporting members and moving it lengthwise to locate its leading end at an elevating position in an oil well derrick. Extending lengthwise of the pipestands adjacent the transfer zone is a steady arm, the end of which nearest the elevating position is pivoted on a horizontal axis. Connected to the other end of the arm are means for engaging the bottom of each lifted pipestand so that when the arm is swung upwardly and over toward the elevating position it can control the trailing end of the engaged pipestand while its leading end is being elevated at the elevating position.

    摘要： Pivotally supported beside an oil well is the inner end of a boom that can be swung in a vertical plane toward and away from the well. Clamping means for gripping a group of drill pipes are pivotally connected to the outer end of the boom on a horizontal axis in such a position that pipes gripped by the clamping means can swing across the boom as the outer end of the boom is raised or lowered, whereby the clamping means can extend downwardly when the boom is in its lower position and laterally toward the well when the boom is in its upper position.
