A drill pipe screen transporter device rotatably couples a drill pipe screen to a transporter for its insertion and/or extraction into and out of a derrick assembly. A first plate assembly has a first base plate; and first and second spacer plates have arcuate notches for engaging the transporter. U-shaped bolts secure the first plate assembly to the transporter. A second plate assembly rotatably connected to the first plate assembly, has an aperture for supporting the screen. A collar assembly, spacer collar and pivot pin rotatably attach the second base plate to the first base plate for rotation of the screen relative to the transporter. A swivel stopper engages the first base plate of the first plate assembly when the second plate assembly is rotated a predetermined amount. A counterweight located opposite to the swivel stopper returns the second plate assembly to its initial horizontal positioning.
