Abstract
An assembly for handling drill pipes includes a basket for drill pipes arranged in rows and columns, and a support table that has a drill pipe receiver. The support table moves laterally with respect to the drill pipe basket between a plurality of column alignment positions and an external position which locates the drill pipe receiver laterally outside of the basket. The support table also moves between the plurality of column alignment positions and the external position. The drill pipe handling assembly also includes a drill pipe elevator assembly and a loader arm assembly comprising a loader arm having a pipe gripper. The loader arm moves between a table alignment position in which the pipe gripper may grab or release a drill pipe when the support table is in the external position and a drilling alignment position in which the pipe gripper may grab or release a drill pipe.
