The invention discloses a concrete prefabricated box girder hoisting device and method, and relates to the technical field of prefabricated box girder installment, the concrete prefabricated box girder hoisting device comprises a hoisting tool, a plurality of strip-shaped holes are formed in the hoisting tool, and two clamping jaws are connected in the strip-shaped holes in an opposite or back-to-back sliding mode; a driving assembly for driving the two clamping jaws to move is mounted at the top of the lifting appliance; the driving assembly comprises a fixing frame installed on the top of the lifting appliance, a guide rod fixedly connected to the fixing frame and a double-thread lead screw rotationally connected to the fixing frame. The two clamping jaws are connected to the guide rod in a sliding mode and connected to the two ends of the double-thread lead screw in a threaded mode correspondingly. A driving motor is installed at one end of the fixing frame, and an output shaft of the driving motor is fixedly connected to one end of a double-thread lead screw. According to the hoisting device, the possibility that the prefabricated box girder slips when being hoisted can be reduced.
