桥梁扳手都有些哪些种类？
What kinds of bridge wrenches are there?
每一个桥梁工程都不是统一的工艺。所以桥梁专用扳手在各所大桥中的应用也是尽不相同，桥梁上用的除了电动扳手还有哪些呢？在桥梁建设中，有很多种类，桥梁专用扳手主要应用于钢箱梁桥梁以及钢桁梁桥梁。桥梁专用扳手有初紧电动扭矩扳手、终紧电动扭矩扳手、手动扭矩扳手、还有轴力扭矩仪、轴力计等。桥梁上用到的高强螺栓型号不同对应的扭矩扳手型号也不一样，还有用于检测螺栓和校验的工具。
Every bridge project is not a unified process. Therefore, the application of special bridge wrenches in each bridge is also different. What other wrenches are used on bridges besides electric wrenches? In bridge construction, there are many kinds of special wrenches for bridges, which are mainly used in steel box girder bridges and steel truss bridges. Special wrenches for bridges include electric torque wrenches for initial tightening, electric torque wrenches for final tightening, manual torque wrenches, axle force torque meters, axle force meters, etc. Different types of high-strength bolts used on bridges correspond to different types of torque wrenches, as well as tools for testing bolts and calibration.
