Abstract
A plurality of vertically spaced rows of substantially horizontal laterally spaced fingers are pivotally supported at one common end on transverse horizontal axes by means mounted on a carriage beneath the fingers. The carriage is movable from a starting location step by step in a direction lengthwise of the horizontal fingers to first locate at a pipe pickup station a pipe supported by the fingers in the upper row nearest their free ends, and then each successive pipe in that row until all of the pipes have been removed from that row. Thereafter, the upper row of fingers is swung up out of the way and the carriage is returned to its starting location so that its step by step movement can be repeated for each successive upper row of fingers after the row above it has been swung up out of the way.
