The invention belongs to the technical field of hydraulic suspension jacking mechanisms, and particularly relates to a hydraulic suspension jacking mechanism system of a girder erection crane. Comprising a motor, a series plunger variable pump, a supporting mechanism, a clamping mechanism and a walking mechanism, the motor is connected with the series plunger variable pump and used for driving the series plunger variable pump to operate, the series plunger variable pump sucks oil from a hydraulic oil tank, a front pump of the series plunger variable pump is used for providing a pressure oil source for the supporting mechanism and the walking mechanism, and a rear pump of the series plunger variable pump is used for providing a pressure oil source for the clamping mechanism. A rear pump of the series plunger variable pump is used for providing a pressure oil source for the clamping mechanism, pressure oil ports of a front pump and the rear pump of the series plunger variable pump are respectively provided with an electromagnetic overflow valve and a direct-acting overflow valve, an outlet of the front pump of the series plunger variable pump is provided with a pressure gauge, and the hydraulic oil tank is provided with a liquid level and liquid temperature meter and an air filter; according to the invention, the four supporting oil cylinders can actively and uniformly distribute the vertical force applied to the flexible bridge by the single suspension supporting mechanism of the crane, so that the stress requirement of the flexible bridge is met.
