Fang Xizhong

Abstract

In order to solve the problems of bolt in steel tube tower such as big fastening torque and small operating space, a special electric torque wrench for high-strength and large-torque bolt fastening in UHV steel tube tower has been researched and developed. The application of this wrench can improve the efficiency and accuracy of fastening, as well as has filled the blank of bolt fastening automation in steel tube tower, which can be overall promoted in the construction of power transmission and transformation projects.
