We have an iron roughneck design for every onshore and offshore drilling application. This includes varying levels of automation, multiple control options, and pedestal or track mounted interfaces. Our iron roughnecks minimize rig floor hazards and streamline the make-up and break-out process, maximizing your uptime and improving crew safety.
