A pipe handling machine having vertical tracks mounted on a rotatable base. A carriage is mounted on the vertical tracks for vertical movement. A multisection telescoping boom is mounted on the carriage, and a pipe-engaging head is mounted on the end of the boom. The base may be carried on a movable trolley, which engages a set of tracks. The tracks run across the rig floor, from well center to a setback area. A second set of tracks may run across the rig floor, transverse to the first set.
