The utility model relates to the technical field of bridge load tests, in particular to a local loading device for a load test of an orthotropic bridge deck of a steel box girder, which comprises a counter-force frame and a loading component arranged on the counter-force frame, the counter-force frame consists of a longitudinal beam, a first cross beam, a vertical column, an anchoring block and a second cross beam, and the loading component is arranged on the longitudinal beam. The main beam is arranged on the second cross beam, and the counter-force action generated by loading the main beam through the loading assembly is finally self-balanced through the counter-force frame. The loading assembly can transversely and longitudinally move in the horizontal direction through a first sliding way and a second sliding way which are arranged on the first cross beam and the longitudinal beam, the deviation of the loading position of the main beam can be reduced, and the loading assembly is suitable for local positio
