Why use a torque limited impact wrench?

Correctly applied torque is vital to maintaining the safety of a vehicle and its passengers. Torque limited tools are essential to helping tighten wheel nuts to the correct torque.

What is a torque limited impact wrench?

An impact wrench with a torque limited function enables efficient torque level control, with torque limited to the forward direction to prevent overtightening. The tool won’t stop running but the torque will increase more slowly, meaning you can be certain that you haven’t overtightened the nut.

Chicago Pneumatic offer the following impact wrenches to help with preventing overtightening on your applications.

 

CP7748TL  1/2″ Impact Wrench

The CP7748TL is a powerful ½” torque limited impact wrench that prevents vehicle service specialists from overtightening nuts during wheel and tyre changing jobs.  The CP7748TL has been designed to offer operators supreme levels of comfort and power, enabling them to quickly apply the correct torque levels and therefore improve productivity while maintaining the safety of a vehicle and its passengers.

Despite its small size, the CP7748TL is torque limited to 90 Nm in the forward direction and delivers a torque of 1,300 Nm in reverse.  As a result, operators can save time changing wheels as bolts are tightened to the right torque faster than using non-torque limited alternatives.

The operator can then simply finish off the tightening with a manual torque wrench.

CP7782TL-6 – 1″ Impact Wrench

The CP7782TL-6 forward mode allows the operator to tighten bolts with confidence as it will limit the torque automatically.  The operator can then simply finish off the tightening with a manual torque wrench.

The main mission of our CP7782TL-6 is to tighten bolts properly according to vehicle manufacturers’ recommendations and to increase the operator’s efficiency.  For tough and hard-to-remove overtightened bolts the CP7782TL-6 delivers high power in reverse upto 2,600 Nm.

It also offers a smooth forward / reverse switch with one torque limited setting in forward and 3 reverse positions to make the operator’s life easier.
