The system comprises two spaced apart arms located on one side of the pipe handling apparatus next to the rack. Each arm has one end pivotally coupled to support structure such that its free end may move upward and downward. The two arms are located in line with ech other with their free ends facing in opposite directions. A lug is connected to each arm close to but spaced from its free end. The lugs extend from their arms outward toward the rack and are employed for holding a length of pipe. A fluid actuated cylinder system is provided for moving the free ends of the two arms upward or downward together for transferring a length of pipe between the rack and the pipe handling apparatus.
