What’s the advantage of a Hydraulic Torque Wrench versus an Impact Wrench?
During the assembly time, the Hydraulic Torque Wrench is a Dynamometric tool within 3% accuracy. An impact wrench is not a dynamometric tool and generates lot of vibration for the operator. During disassembly time, Impact wrench is the best support to finish the breakout job of the hydraulic torque wrench. During assembly time, a small impact wrench is welcome to sit nuts before to use the Hydraulic torque wrench. The daily use of impact wrenches is now limited. Exposure to vibration from power tools is by far the greatest concern. Hand-held power tools such as impact wrenches can cause “hand-arm vibration syndrome.” This disorder is also known as “vibration-induced white finger”, “hand-arm vibration syndrome (HAVS)”, or “Raynaud’s phenomenon of occupational origin.” Raynaud’s phenomenon, however, is only one aspect of the hand-arm vibration syndrome. Vibration also damages nerves, muscles, bones and joints of the hand and arm.
