Electric Torque Multiplier

  • alkitronic® EF-S electrical torque multipliers for 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 900 to 9,800 Nm (665 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.

Quality bolting with torque/angle method.

  • Innovative motor protection with automatic shutdown to ensure
    bolting quality.
  • Intelligent processor-controlled shut-off electronics for constant
    exact reproduction of the preselected torque.
  • Repeat shut-off accuracy ± 2% for the same bolting application.
  • Exceptionally robust motor housing (aluminum alloy).
  • For safe, comfortable tool guidance, model-specific operating and
    holding handles are included in the scope of delivery. These can be
    mounted as required at several fastening points provided.
