ABSTRACT:
Pipe handling apparatus for transporting pipe between a derrick floor and a pipe rack by a cable-way. A portion of the cable overhangs the derrick floor and the pipe rack. Spaced apart pipe receiving carriages are supported by the cable and are provided with means for being moved from a location adjacent to the derrick floor to a location which overhangs the pipe rack. The tension of the cable is controlled in a manner which enables the pipe receiving carriages to be vertically positioned with respect to the pipe rack.
