The invention discloses a tilting control method for a rear-beam multi-functional hydraulic station of a single-lifting sling quay crane. According to the tilting control method, the existing rear-beam oil cylinder zero setting position is changed; the initial zero position of an oil cylinder is set at the position where the stroke of the oil cylinder is largest; when the tilting or balancing function is achieved under control, an action instruction is sent by an operator; after the instruction reaches a main control system, a corresponding control program is activated, and then the opening-closing of a corresponding electromagnetic valve is controlled through logic output; and finally, the corresponding function can be achieved as long as the corresponding oil cylinder is controlled to perform retracting action. By adoption of the tilting control method disclosed by the invention, the function of the rear-beam multi-functional hydraulic station in actual production can be optimized, the practicability can be improved, and the equipment production and use cost can be reduced to a certain extent.
