Apparatus and methods for moving a tubular member to and from an elevated drilling rig floor. A support structure has an elongate indentation in its upper surface. A ramp assembly comprises telescoping assemblies having nested tubular elements extendable between retracted and deployed positions, thus forming a guide extending from the elongate indentation towards the drilling rig floor. Indexers may urge the tubular member towards or away from the elongate indentation. Kickers may urge the tubular member into or out of the elongate indentation, and may be operable via actuators which also operate the indexers.
