Alkitronic® - Detailed description

  • Primary operation unit: on/off switch of the machine; slow and comfortable right/left rotation for safe and precise positioning of the torque wrench (toggle switch) as well as for the starting of the bolt tightening process.
  • Speed, frequency and torque are correspondingly regulated and controlled. Microcontrolled monitoring combined with a processor controlled switch-off electronic guarantee a precise repeatability of the pre-set torque. Repeatable accuracy for shutoff is +/- 5% for identically soft and hard joints.
  • Two principles of construction within one tool:
    A = free joint tool - the drive unit (motor) can independent of the gear box be fully rotated even when the reaction arm is already in its position
    B = Fixed joint between motor and gear box - mechanically reversible (rigid connection)
  • Secondary operation unit: Adjustment of the shutoff torque and sense of rotation (LED version). The LCD version displays the actual torque values on the display.
  • LED-Display: light-emitting diode displays the pre-set torque within 19 stages together with the direction of rotation
  • Secondary operation unit: Adjustment of the shutoff torque and sense of rotation (LED version). The LCD version displays the actual torque values on the display.
  • LC-Display (optional): pre-set torque and sense of rotation are both displayed alphanumerically on an illuminated LCD display.
