The invention relates to an inclination repair process of a top beam of a ship loader. The inclination repair process specifically comprises the steps of (1) temporarily welding and reinforcing a wedge-shaped steel plate and a peripheral U-shaped steel plate for protection; (2) designing a repair scheme according to a drawing and onsite actual conditions; (3) satisfying the maintenance space by utilizing a floating crane and a crane main arm; (4) resetting a tower beam; and (5) welding a reinforcing piece, applying and painting, and cleaning up the scene. The invention provides the repair process of the top beam of the ship loader, which is different from a traditional repair process of the top beam of the ship loader, and no long maintenance time is needed for removing a winding steel wire rope and the top beam; during repair, on the basis that the winding steel wire rope and the top beam are not removed, and the floating crane is matched with a chain block, so that the repair is completed on the premise that hoisting parameters of hoisting equipment are not enough, the influence of long maintenance time on the production is avoided to the maximum, the efficiency is improved, thecost is reduced, and the effects of safety and reliability are achieved.
