電動扳手是指擰緊和旋松螺栓及螺母的電動工具，是一種擰緊高強度螺栓的工具。用于鋼結(jié)構(gòu)橋梁、廠房建筑、化工、發(fā)電設(shè)備安裝大六角頭高強度螺栓施工的初擰、終擰和扭剪型高強度螺栓的初擰，以及對螺栓緊固件的扭矩或軸向力有嚴格要求的場合。
Electric wrench refers to an electric tool for tightening and loosening bolts and nuts. It is a tool for tightening high-strength bolts. It is used for initial tightening, final tightening and initial tightening of torsional shear high-strength bolts in the construction of large hexagon head high-strength bolts for the installation of steel structure bridges, plant buildings, chemical industry and power generation equipment, as well as occasions with strict requirements on the torque or axial force of bolt fasteners.
電動扳手出口歐盟，需要出示產(chǎn)品CE認證證書報告，用以證明滿足歐盟ce認證要求。
When the electric wrench is exported to the EU, the product CE certification report shall be presented to prove that it meets the EU CE certification requirements.
