AWS TT-41050F-IMP Impact Torque Test System, 5-50 lb-ft, Includes Display and Run-down-fixture

Price: $ 3,995.00

AWS TT-IMP Impact Wrench Torque Tester
Capacities up to 5000 lb-ft / 6800 Nm
Made in the USA

The AWS TT-IMP Impact Wrench Torque Tester is specially designed with extra-rugged construction for the demanding job of testing impact tools. The flange-mounted transducer is fixed in a heavy-duty frame designed for secure bench top mounting. A digital display is connected remotely to isolate the electronics from the damaging vibrations caused by impact tools. A specially designed spline drive run-down-fixture simulates real-world application conditions, allowing the impact tool motor to ramp-up to freely rotate several times before building resistance to rotation.

The included digital indicator can display torque in lb-ft, N-m, Lb-in or Kg-m (selectable) with an accuracy of +/-1% (bi-directional with optional reverse threaded run-down-fixture).

Notes for Impact Testing

  • Set filter on AWS-4050 Torque Display to 1000 Hz
  • Back off run-down between each test
  • Be aware of heat build-up, it breaks down the lubricant in the run-down fixture, increasing friction. Let the run-down cool after a few minutes of use (this will vary by torque range)
