Pipe handling system for presenting sections of pipe to a derrick work floor having a pipe ejection assembly

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 pipe ejection assembly, integrated into said boom, is operable as the boom lowers into the cavity for the purpose of laterally ejecting pipe from the trough. The ejection assembly is adaptable for unidirectional or bidirectional ejection. Motive means are provided to permit powered movement of the ejector members when the boom is nested.
