Electric torque multiplier/torque wrench series EF by alkitronic

Electric Torque Multiplier (EF)


  • alkitronic EF-S/EF-A electrical torque multipliersfor torques of 430 to
    42,000 Nm (315 to 30,980 ft.lbs).
  • Consistent torque accuracy on all international power supplies
  • Precise shut-off torque also operates with voltage-controlled portable generators.
  • Models alkitronic EF-A in angled design with high operating comfort
    in confined spaces for torques of 430 to 9.800 Nm (315 to 7,230 ft.lbs).


  • Low running costs due to maintenance-free, low-wear, brushless synchronous motor with excellent efficiency.
  • High motor speed: Up to three times faster than conventional electrical torque multipliers.
  • Permanent higher joint quality compared to ratchet torque tools by continuous rotation of the square drive.
  • Menu-guided intuitive operation, with control and warning signals.
  • OLED-Display anti-glare and high contrast - for perfect reading
    under all weather conditions.
  • Comfortable working due to the 360° rotatable motor unit; in addition,
    hardly any reaction forces are transmitted to the user.
