The easy-to-operate EFCip40 250Nm - 1500Nm electric torque multiplier is designed for precision tightening and loosening of all heavy duty fastening applications.

From tightening large industrial bolts used in windmill gearbox assemblies to bolting maintenance applications for oil & gas pipelines and rigs, this Mountz torque multiplier achieves precision torque in a quick, cost-efficient manner.

This electric torque multiplier has an accuracy better than ± 5%.


  • Precision tightening and loosening of all heavy duty fastening connections.
  • This electric torque multiplier shuts-off when pre-set torque is achieved. It is non-impacting and operates at a smooth, continuous rotation.
  • It increases speed and productivity because it is 5-10 times faster than slow ratcheting hydraulic wrenches. This tool is also less expensive than hydraulic wrenches.
  • It is ergonomically safer than the harmful hammering of impact wrenches and eliminates the frequent and costly repairs associated with impact wrenches.
  • Microprocessor controlled. The speed, frequency and torque correspond with a built-in controller (no separate box needed).
  • Features a brushless motor design which provides low maintenance.
  • Has over-heat protection.
  • Universal AC Input (100-253V / 45-66 Hz).
  • The handle can free float or locks in a set position.
  • Protected against dampness and spattered water through its IP54 rated protection.
  • Supplied with a reaction foot.
