Find out how our impact drivers and wrenches are designed for longer run time and higher performance in light- to heavy-duty driving and bolting
Independent studies have identified poor construction procedures as one of the main causes of structural failure, while the American Construction Inspector Association reveal that over-and under-torqued anchors are the number-two reason for failed jobsite inspections.
And maybe it is no wonder, when the available tools do not match the current demands. To correctly install an anchor your choices are between a slow and imprecise torque wrench, cumbersome torque bars or a powered impact wrench, which lets productivity soar while safety and reliability slump.
Now, with Hilti's Adaptive Torque (AT) system, you don’t have to compromise.
The AT system is made up of four components:
Intelligent cordless impact wrench for installation of torque-controlled metal expansion anchors
Lightweight interface module used to generate installation data and reports.
Ultimate-performance expansion anchor for cracked concrete and seismic (CS)
Use the SI-AT-A22 module’s built-in scanner to read the barcode on your box of anchors. The SIW 6AT-A22 impact wrench then adjusts the torque setting to meet certification requirements. Tap the lock button to confirm your selection, and the impact wrench is ready to use
With the SIW 6AT-A22 impact wrench, all you need to do is pull the trigger and let the tool work. As soon as the SI-AT module lights up green, you know the anchor has been torqued to exactly the right level to comply with ETA and ICC-ESR approvals.
Giving you confidence that the anchor has been correctly installed, sensors in the SIW 6AT-A22 recognize if an anchor has been loosened and, on retightening, will restore the correct torque. And with the AT System can you adjust and retorque up to three times.
Full accountability has never been easier. Simply connect the SI-AT-A22 module to a computer using a standard USB cable and the AT Documentation Software then downloads performance data stored by the SI-AT-A22, which can be used to produce an installation report.
The report lists all products used, the method of selection (scan or manual) and completion time and date.
From a specifier’s perspective, this report proves that the anchors have been correctly installed and meet certification requirements. From an installer’s point of view, it can help you breeze through site inspections.
The SIW 6AT-A22 impact wrench is intelligent enough to detect an anchor which has been tightened and then loosened again, a function which is useful for straightening or aligning neighboring fixtures, such as railings and windows.
During this process the SI-AT-A22 module will use an algorithm, develop from over 10,000 tests, to retightening the anchor ensuring no over-torqueing occurs. Once complete, SI-AT-A22 provides a visual indication to the operator by flashing a yellow light, displaying a notification on display and plays a sound.
