  1. Comprehensive control electronic:
    The EDS maintains continuous control of the tightening process and automatically adjusts the rotational speed according to the application.
  2. Automatic free-run:
    Once the previously set torque value has been reached the EDS automatically initiates “free-run”, relieving torsional binding at the reaction point for easy and safe removal of the tool after each bolting process.
  3. Suitable for on-site construction:
    The powerful motor is made to withstand the drastic voltage fluctuations common with using on-site generator power supplies.
  4. Optimal for international machine outfits:
    Automatic detection and adjustment to 50 Hz or 60 Hz power supplies.
  5. 2 gear stages:
    For changing between low and high gear.
  6. Precision:
    High degree of reproducibility of thetorque values up to ± 3 %.
  7. Independent rotation between handle and gearbox
    ensures steady and optimal positioning of the ITH EDS
