The invention provides a method for synchronously replacing a gantry beam and steel wire ropes of a ladle crane. The method comprises the following steps: disconnecting old steel wire ropes from an old gantry beam, dismounting the old steel wire ropes, then directly winding the old steel wire ropes on corresponding pulleys of a new gantry beam, then fixedly connecting the old steel wire ropes to form complete steel wire ropes, fixedly connecting rope ends of the old steel wire ropes connected with balance bars to rope ends of new steel wire ropes, dragging the new steel wire ropes via the old steel wire ropes to be wound into pulley blocks under winding driving of a winding drum set, dropping the old steel wire ropes down, winding the old steel wire ropes out, and winding the new steel wire ropes in, thus synchronously replacing the gantry beam and the steel wire ropes. Through the method, the power of rotation equipment is fully utilized in the replacing process; the operating efficiency is effectively impro
