Impact tool is driven by rotation of the impact hammer spindle body, produce a torque, this design makes hammering group easy to wear, so that the tool life is too short; oil pulse tool is rotated by the hydraulic cylinder, the use of oil pressure generating torque, and therefore the durability of its drive member much longer than the impact tool.

 

Hydraulic connection EYP model pulse-handed use; when EYP oil pulse wrench breathe (when tightening is completed) the screen will display the number of remaining tighten; built-station selection function, it is possible to tighten the number corresponding to four kinds of different working position; pour tighten count the number of leakage occurs when play will display a warning on the screen; error correction system can only go in a clockwise direction to tighten a bolt or nut when starting the countdown number; bolt or nut counterclockwise direction to tighten the error correction system will not start; no countdown when idling; can set parameters simple operation on the touch screen; text screen display to select two languages Chinese and English.

This system is a pulse pressure changes occur wrench induction EYP series of hydraulic operation, the number of correct countdown bolts tightened. In case of leakage hit the screen will display a reminder for accurate screwed tight job management system.
