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. The shut off valve controls the tightening process, while the torque reaction is taken by a reaction bar. The BlueTork nutrunner enables operators easily to re-set torque for each use, providing accurate, precise tightening to the original equipment manufacturer's guidelines. This is particularly important for vehicles with frequent start-stop journeys, such as those taken by city buses or refuse trucks' says Christophe Roland, product marketing manager at Chicago Pneumatic Tools. In addition to providing operator comfort, the BlueTork nutrunner performs an important function in the wheel tightening process. 'The BlueTork nutrunner is a unique piece of equipment for organizations who are looking to improve their fleet maintenance in terms of quality, ergonomics and reliability. 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 provides high user-comfort when handled, and can reduce maintenance issues.
