alkitronic® EF-A Electric Torque Wrench/Torque Multiplier
Applications:
- 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 430 to 9.800 Nm (315 to 7,230 ft.lbs).
Advantages:
- 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.
