ABSTRACT:
A pipe handling apparatus for raising and lowering pipe to and from a raised derrick work floor. The apparatus comprises a longitudinally-extending base, with a longitudinally-extending cavity therein. An elongate, longitudinally-extending boom member is provided, which is adapted for raising out of and nestable positioning in such cavity. The boom member has a longitudinally-extending trough therein on an upperside surface thereof, adapted to receive at least one section of pipe. At least one arm member is coupled to the boom member for raising a proximal end of such boom member. A carriage member, slidably coupled to the boom member, is moveable longitudinally along the boom in the trough. The carriage member is adapted to engage and slidably transport one end of the pipe along the trough. Motive means are provided to permit powered movement of the carriage member along the boom.
