Abstract: A system for delivering a tubular pipe segment from a ground level to an elevated drill rig floor. A pipe assembly system based at the ground level includes a bucking unit for connecting a first joint and a second joint to form the tubular pipe segment, a powered first conveyor for moving the first joint into the bucking unit, a first staging pipe rack, a powered second conveyor for moving the second joint into the bucking unit, and reversible for moving the tubular pipe segment out of the bucking unit, a second staging pipe rack for storing a plurality of joints, and a transfer pipe rack for storing a plurality of tubular pipe segments.

Abstract: An apparatus for delivering drill pipe has a support frame, a catwalk platform, and a slide platform that are pivotally connected together. A drill pipe rack, a chain drive, and a kicker direct the drill pipe to and from the catwalk platform. A hydraulically actuated piston lifts the catwalk platform and slide platform into alignment to create a single inclined delivery platform extending from the ground to the rig floor. A powered means lifts or lowers the drill pipe along the delivery platform.
