description	The invention discloses a turnover tool for manufacturing a steel structure box type bridge and a turnover method of the turnover tool. The technical problems that in the prior art, the efficiency is low and the turnover cost is increased when a steel box beam is manufactured and turned over are solved. The turn-over tool comprises a steel structure frame, a bottom steel beam, a left vertical steel beam, a top steel beam, a right vertical steel beam, a first lifting lug and a second lifting lug. The turn-over method comprises the steps that the turn-over tool is assembled to the steel box girder, a main hook of a movable crane hooks a first lifting lug for lifting so that a second circular ring can be grounded, the movable crane runs so that the first circular ring and the second circular ring can be stably grounded, then the main hook hooks the second lifting lug, the main hook is lifted so that the first circular ring can be grounded, and the main hook is lowered so that a top steel girder can be stably gro
