Abstract:

The test blocks used in bridge crane loading test in China are usually borrowed from other hydropower plants; however, in abroad especially less developed area, it is difficult and uneconomical to purchase and transport the test blocks. Aiming at this problem, taking the Song bung 4 hydropower plant in Vietnam as a case, the method of the bridge crane loading test by using hydraulic dynamometer is presented, and the basic working principle, main equipment, test procedure and testing process by the third-party organization are also introduced. The testing result shows that the method can verify the technical parameters and the safety performance of bridge cranes, which is a reference to other oversea hydropower projects.
