The invention provides a hydraulic supporting leg leveling device, a floating type tower crane and a control method of the floating type tower crane. The hydraulic supporting leg leveling device comprises a supporting leg upper structure, a hydraulic oil cylinder, a hydraulic oil cylinder piston rod, a leveling nut, a driving mechanism, a supporting leg lower structure, a ball head supporting rod and a ball head seat. The top end of the outer portion of the supporting leg upper structure is used for a bottom frame structure of the floating type tower crane, the hydraulic oil cylinder is arranged in an inner cavity of the supporting leg upper structure, external threads of the leveling nut are connected with internal threads of the supporting leg upper structure, and the driving mechanism is fixedly connected with the supporting leg lower structure and connected with the leveling nut through the transmission mechanism. The driving mechanism is used for driving the leveling nut to rotate so as to adjust the landing leg upper structure to ascend or descend. According to the invention, the purpose that the whole machine floats above hydraulic pressure is achieved through an up-and-down separated supporting leg structure and an integrated hydraulic leveling device, so that the leveling function of the tower crane is easy to realize; by means of the principle of communicating vessels, hydraulic oil flows in the four oil cylinders in a sealed mode, and linkage leveling of the four oil cylinders is achieved.
