Alkitronic Electronic Radial Torque Wrenches

Other torque tools

  • The electric alkitronic Radial Torque Wrenches are used to loosen or tighten bolted connections and spindles. The reaction moment is absorbed by means of a specifically designed support. This constructions guarantees bolting of up to 6000 Nm. The alkitronic Radial Torque Wrenches are continously rotating and specifically designed for applications on plate heat exchangers.

Alkitronic - Detailed description
Blocking pin for use of the machine as rigid version (fixed joint motor/gearbox)
Locking pin for use of the machine as rigid version (fixed joint motor/gearbox)Trigger
One-handed operation, four-edge operation button for clock wise, counter clock wise, toggle start and start commands
  • Primary operation unit: on/off switch of the machine; One-handed operation: comfortable, slow 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.
  • Integrated motor protection: for safety reasons an automatic thermal overload switch is built in as well as a permanent cooling fan that keeps running after the safety shutoff and thus provides short periods of cooling.
  • Two principles of construction within one tool:
    A = swivelling: 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 = Rigid: Fixed joint between motor and gear box - mechanically reversible
Electric Torque Wrench
  • Secondary operation unit - Type EFC

    : light-emitting diode displays the pre-set torque within 19 stages together with the direction of rotation
