Electric torque multiplier/torque wrench series EF by alkitronic

Electric Torque Multiplier (EF)


  • alkitronic EF/EFW electrical torque multipliers for torques of 400 Nm to 42,500 Nm.
  • Consistent torque accuracy on all international power supplies 100-253 V / 45-66 Hz.
  • Precise shut-off torque also operates with voltage-controlled portable generators.
  • Models alkitronic EFW angled tools for comfortable operation in areas difficult to access.


  • 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.
  • Ergonomic and comfortable operation: The 360 degree rotating handle prevents reaction forces from being transferred to the operator.
