Pneumatic torque multipliers/torque wrenches series CL by alkitronic

Pneumatic Torque Multiplier (CL)


  • alkitronic CLS: quick, compact torque multiplier for torques of 60 Nm to 3,500 Nm
  • alkitronic CLD: comfortable torque multiplier with rotating handle for torques of 160 Nm to 9,800 Nm
  • alkitronic CLS2: high-performance 2-gear machine for torques of 120 Nm to 48,000 Nm
  • Continuous rotation, tightening, or loosening for all heavy duty fastening connections
  • Perfect for bolted applications in hazardous, explosive environments


  • Permanently higher joint quality, compared to impact and hydraulic wrenches by continuous rotation of the square drive
  • alkitronic CLD - the 360 degree rotating handle ensures comfortable operation. No reaction forces are transferred to the operator
  • alkitronic CLS2 with fast gear for turning in and simple, quick switching to power gear (is used for applying the final torque)
  • Low maintenance requirements: the compact design and the motor housing made of cast aluminum ensure stability, corrosion resistance and break resistance.
  • Simple 1-finger trigger operation for forward and reverse.

alkitronic specials

  • Simple 1-finger operation for right/left rotation, option to enable the reaction to be locked in one position

  • Proven high-performance gears, produced in a chip-free, high-precision process
  • alkitronic CLS2 with uniquely high torque - 48,000 Nm
  • Optional silencer levels to reduce the noise from the motor exhaust on request

Specifications: On request, you will receive our pneumatic multipliers with ATEX-Certification: II 2 G D c IIB T6

Prerequisites for best work with the indicated torques are an operating pressure of 2-7 bar at a volume flow of approx. 10-15 l/s. The torque accuracy depends on the stability of the supply system.
