1. The machine solves the spark problem of the brush motor from the principle, and can operate efficiently and stablyextending the service life of the carbon brush to a greater extent

2. Stable torque outout. not easily affected by voltaae fluctuations and long distance cable,suitable for construction site applications.Precision +5%repeatability±2%

3. Continuous rotation without impact automatic stop when the preset toraue value is reached much more efficient than intermittently driven hydraulic wrenches

4. Three operating modes: torque modetorque+rotation angle mode and fast mode

5. Use of multi-stage gearbox.High reliability,high stability 

6. Standard counter acting force arm as the standard confiquration, custom counter acting force arms available

7. 110V-220V AC power no need for an external pumping station and pipes.
