Over-torqued and under-torqued anchors are among the most common causes of failed jobsite inspections.
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 three components:
- SIW 6AT-A22 cordless impact wrench: it looks and works like the previous Hilti SIW 22-A cordless impact wrench but is equipped with intelligent electronics, a more robust anvil and a sleeker nose which can reach into tighter spaces.
- SI-AT-A22 AT module: a small, very light interface which slots in between the impact wrench and battery. It crunches live data from the SIW 6AT-A22 to recognise when an anchor has been correctly installed.
- Documentation software: Ensures that the AT module's job history can be transferred to a computer and used to create a detailed installation certificate.
AT-ready tools are equipped with the sensors and on-board intelligence to confirm if an anchor has been torqued according to ETA approvals. The operator simply inputs which anchor is being used – simply by scanning the box with the AT module integrated barcode reader – and the tool does the rest. Afterwards, the tool can be connected to a computer to instantly generate an installation report, offering inspectors and specifiers a guarantee that the work has been carried out exactly as specified.
