Abstract: A pipe-conveying catwalk has a ramp affixed to the floor of a drilling rig and a main frame ground supported adjacent to a pipe rack so that pipe can be conveyed between the rack and the derrick floor. Pipe is rolled from the rack into a trough which forms part of a stinger. The stinger is nested within a boom and can be telescoped to extend longitudinally away from the boom. The boom is retracted into nested position within the main framework. One end of the boom is attached to the main frame by an extensible swing arm apparatus which elevates the outer end of the boom while the other end of the main frame is attached to the rig floor by a ramp which moves the other end of the boom from the nested position vertically upwards and towards the rig floor. A pipe is rolled from the pipe rack into the trough, the boom is elevated into an inclined position such that the stinger telescopes from the boom to position the box end of the pipe in overlying relationship respective to the derrick floor.
