摘要
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.
