EAF Battery driven torque multiplier 160- 6000Nm Made in Germany


  • Integrated fully-automatic release function: Caused by high torsional force, it is often impossible repositioning the multiplier on the next bolt joint. The automatic release function enables a fast, secure “run free“ of the reaction absorber DMA and also relieves stresses within the multiplier
  • Low running costs: The low-wear, synchronous motor is maintenance free
  • Health-preserving: Low weight, ergonomically designed, low noise emissions. No noise protection necessary
  • High performance: Two lithium-ion battery packs ensure up to 360 screw joints in a row. Each battery features an LED charge level indicator
  • Exact shut-off torque even at low battery levels.
