The invention provides an automatic hoisting system and method for a gantry crane. The automatic hoisting system for the gantry crane comprises a cart mechanism, a trolley mechanism, a hoisting mechanism and a plate turnover mechanism. The cart mechanism moves along the direction of the construction track; the trolley mechanism moves in the length direction of the beam. The lifting mechanism drives the lifting appliance to move in the vertical direction; the plate turnover mechanism is cooperated with the hoisting mechanism to turn over the muck box; a control system of the cart mechanism, a control system of the trolley mechanism and a control system of the hoisting mechanism are all in communication connection with a PLC, absolute value encoders are further arranged in the cart mechanism, the trolley mechanism and the hoisting mechanism and are configured to obtain three-dimensional position information of the lifting appliance, and the PLC is configured to automatically control movement of the cart mechanism, the trolley mechanism and the lifting appliance according to the three-dimensional position information; an anti-swing program is further preset in the PLC, and the anti-swing program is configured to automatically adjust the speed of the cart mechanism, the speed of the trolley mechanism and the speed of the lifting appliance according to the three-dimensional position information; the hoisting mechanism further comprises a metal flaw detection device used for monitoring the state of the steel wire rope.
