• For large bolt tightening, such as construction machinery.
• Automatic torque converter enables stable bolt tightening high speed for provisional tightening and low speed for final precise tightening. • Fluctuation of the air pressure does not affect the accuracy and repeatability. • Easy torque adjustment with graduation. • Unlock device releases all reaction forces which prevents the removal of the tool after the bolt has been driven to the desired torque. • Reaction force is automatically and safely absorbed in any position with a universal reaction arm. • Since the reaction arm rotates free, the positioning can easily be made by moving the reaction arm.
