A well pipe handling machine is described for use in a rig having a floor and having a string of pipe extending vertically along an axis of a well and having a rack for receiving and holding a series of pipe sections from the string in essentially vertically extending condition. It consists of: a support column structure which is movable horizontally to store the sections of pipe in the rack or retrieve them therefrom; two vertically spaced pipe holding units carried by the support column structure for movement therewith and adapted to hold a section of pipe in vertical condition during such movement; upper and lower carriage structures connected to upper and lower ends respectively of the column structure; two synchronized drive mechanisms for actuating the carriage structures generally horizontally in correspondence with one another; pivotal connections attaching upper and lower ends of the column structure to the upper and lower carriage structures respectively for pivotal movement about a vertical axis offset from the axis of the well to face the rack; powered means for pivoting the column structure relative to two carriage structures; tracks adapted to extend horizontally along the rig floor and guide the lower carriage structure between the first and second positions; a third carriage structure mounted to the column structure; means for actuating the third carriage structure upwardly and downwardly; a parallelogram mechanism mounting the two pipe holding units to the third carriage structure.
