Introduction of Constant Torque Electric Spanner for Bridge Construction随着改革开放的不断深入，的基础设施越来越多，桥梁建设是必不可少的。系索桥是桥梁建设的主要形式。螺栓连接必须采用大六角高强度螺栓。

　　With the deepening of China's reform and opening up, China's infrastructure is increasing, and bridge construction is indispensable. Tethered bridge is the main form of bridge construction. Large hexagonal high strength bolts must be used in bolt connection.

　　大六角高强度螺栓一般为10.9级或12.9级。根据高强螺栓的施工工艺要求，高强螺栓的施工必须先紧固，再紧固。初始拧紧一般为比较大扭矩值的50% ~ 60%;比较后的紧固必须达到螺栓规定的比较大扭矩值。

　　Large hexagonal high strength bolts are generally of grade 10.9 or 12.9. According to the construction technology requirements of high-strength bolts, the construction of high-strength bolts must be tightened first and then. Initial tightening generally ranges from 50% to 60% of the maximum torque value; final tightening must reach the maximum torque value specified by the bolt.

　　大六角高强度螺栓结构，初拧紧时可选用手动扭矩扳手，固定扭矩电动扳手，比较后拧紧时必须选用前田扭矩电动扳手。

　　Large hexagonal high strength bolt structure, the first tightening can choose manual torque wrench, fixed torque electric wrench, the last tightening must choose the front field torque electric wrench.

　　桥梁施工选择螺栓通常m2-m24和(大六角高强度螺栓,包括m2-m24比较大扭矩值通常是860海里(比较大扭矩值根据不同的摩擦系数,以及不同),(比较大扭矩值通常是1700海里(比较大扭矩值根据不同的摩擦系数,以及不同)早期紧,需要选择扭矩电动扳手,设置初始拧紧力矩值,开始打螺栓,拧紧几秒钟后，停止电动扳手紧固，取出套筒。

　　In bridge construction, bolts are usually M2-M24 and (large hexagonal high strength bolts, including M2-M24 maximum torque value is usually 860 nautical miles (maximum torque value is based on different friction coefficients, and different), (maximum torque value is usually 1700 nautical miles (maximum torque value is based on different friction coefficients, and different) early tightening, it is necessary to select torque electric wrench, set initial tightening moment value, and start to tighten bolts. After a few seconds, stop fastening the electric wrench and take out the sleeve.

　　比较后拧紧时，需要固定扭矩电动扳手，先将扭矩值设置为螺栓的比较大扭矩值。拧紧几秒钟后，电动扳手停止拧紧，可以取出。

　　Finally, when tightening, it is necessary to fix the torque electric wrench. First, the value of the torque is set to the maximum value of the bolt. After tightening for a few seconds, the electric wrench stops tightening and can be taken out.

　　初拧紧时可选用通用固定力矩电动扳手，末拧紧时必须选用前田固定力矩电动扳手，扭矩大，误差小，精度高。

　　The universal fixed moment electric wrench can be used in the initial tightening, and the front field fixed moment electric wrench must be used in the final tightening. The torque is large, the error is small and the precision is high.

　　用法:
