Iron Roughneck Designed specifically around the latest in automated controls, National Oilwell’s Iron Roughneck maxi- mizes the efficiency of the total pipe handling opera- tion.  Greater speed and the ability to automatically perform simultaneous functions means more time saved on every pipe connection. It’s compact size and light weight makes the machine ideal for a variety of unique positioning systems that optimize drillfloor configuration and increase safety. Through the use of advanced controls, pipe threads are engaged and separated gently; extending the life of expensive tubulars and minimizing connection fail- ures. •  Maximized pipe handling efficiency... • Less time spent at each pipe connection... •  Optimized drillfloor configurations... •  Increased safety... •  All resulting in added value for the drilling operation. 83 3 1 /2^" to 9 3 /4^" (89mm to 248mm) 125,460 ft. lbs.   (170,000Nm) 53 GPM @ 3000 PSI   (200 LPM @ 207 bar) 230 VAC, 16 Amps for Control System 100 RPM 2 7 /8^" to 9 3 /4^" (73mm to 248mm) 2,215 ft. lbs.  (3,000 Nm) 60° Continuous Hydraulic Supply: Electrical Supply: Power Requirements Maximum Torque (Make or Break): Maximum Pipe Spinner Speed: Size Range for Pipe Spinner: Maximum Torque Wrench Rotation: Maximum Pipe Spinner Torque: Size Range for Torque Wrench: Performance  of  IR-170
