The BlueTork nutrunner provides high user-comfort when handled, and can reduce maintenance issues. Since the tool uses continuous driving force, instead of impact force, it is quiet at 79dBA, with vibration of less than 2.5m/s. The BlueTork nutrunner enables operators easily to re-set torque for each use, providing accurate, precise tightening to the original equipment manufacturer’s guidelines. The shut off valve controls the tightening process, while the torque reaction is taken by a reaction bar. The tool uses a dual motor setup which provides initial run-down at 100 rpm (50 ft.lbs) to quickly snug the nut, while the second motor rotates at 8 rpm to deliver the final specified torque.
