Chicago Pneumatic’s BlueTork Nutrunner

Chicago Pneumatic is promoting its BlueTork CP7600 nutrunner series as “the most reliable and ergonomic solution for truck and bus tyre changing operations”. According to the company, the BlueTork nutrunner can tighten wheel nuts to a precise specification without using impact force. It is purportedly the only non-impact tool with a shut-off nutrunner available on the market for fleet maintenance applications.

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 is a unique piece of equipment for organizations who are looking to improve their fleet maintenance in terms of quality, ergonomics and reliability. In addition to providing operator comfort, the BlueTork nutrunner performs an important function in the wheel tightening process. 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.

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 100rpm (50 ft.lbs) to quickly snug the nut, while the second motor rotates at 8 rpm to deliver the final specified torque.

The BlueTork nutrunner is available in four versions (seven models): the CP7600 with one torque setting in forward only; the CP7600R with one torque setting with forward and reverse; the CP7600-4P which features four torque settings in forward only; and the CP7600R-4P, featuring four torque settings with forward and reverse.
