ABSTRACT:
An apparatus for picking up and laying down pipe is arranged so that pipe movement is directed toward the hole axis or rotary table. When the pipe carrier stops movement toward the hole axis, the end of the pipe joint being delivered toward the hole is positioned above the rotary table and beyond an upstanding support carried by the rig which carries the load of the pipe joint and pipe carrier.
