The invention provides a mounting method of a ship crane; the ship crane comprises a crane column; and the crane column consists of an upper column body and a lower column body. The method comprises the following steps: (1) the upper column body and the lower column body are assembled and welded as a crane column integer in an internal field of a workshop; (2) two steel structures are freely cooled to release internal stress therebetween; (3) after the crane column integer is cooled and connected as a whole, the upper surface of the crane column is machined, so that the upper surface of the crane column is perpendicular to a column body center line of the crane column; (4) the machined crane column is carried to a dock, and is lifted on to a ship for mounting through another lifting device in a state of stable ship body; and (5) remainder crane components are continuously mounted. The method not only can reduce the workload of working at heights on the ship and improve the working environment, but also can effectively guarantee the mounting precision and relieve the labor intensity so as to overcome the defects of high labor intensity and weak working environment in the mounting process.
