Impact wrench

Reverse impact wrenches PGU of pistol type are intended for screwing up and unscrewing of screw joints during assembling  and disassembling  works performance at the assembly enterprises, in automobile industry and heavy industry.

Due to the pulse impact mechanism the impact wrench surpasses by power any usual  wrench. When impact wrench working the compressed air enter the working chamber of the air drive. The impact pulse mechanism will transform continuous rotary movement into the periodic mechanical pulses. Thus the great torques provides the reliable tighten even of  big nuts. It is possible to screw and unscrew with convenience and with much less time.

Impact wrench increases the force smoothly and within a wide range, that allow to screw up or unscrew thread joints of different rigidity. Torque value and a number of revolutions are adjusted by  compressed air pressure, supplied to the impact wrenches.

Impact wrenches have the significant impact force with rather small dimensions and weight. The location of the easy and strong handle of coal-plastic with small section and structured surface provides the especial ergonomics for the tool. An optimum location of the gravity center, and also the clamp for spring suspension guarantees the reliable work.

The impact mechanism of the wrenches due to design features and applied materials is reliable, that provides long service life of the wrenches.
