The invention discloses a supporting system of multi-group hydraulic suspension oil cylinders of a tire type crane, and the supporting system comprises a hydraulic loop CG, a hydraulic loop BH, a hydraulic loop AF, an oil inlet loop P and an oil returning loop T. Sixteen hydraulic suspension cylinders are divided into three groups, the first group of hydraulic suspension cylinders comprise a firsthydraulic suspension cylinder, a second hydraulic suspension cylinder, a third hydraulic suspension cylinder, a fourth hydraulic suspension cylinder and a fifth hydraulic suspension cylinder, the second group of hydraulic suspension cylinders comprise a sixth hydraulic suspension cylinder, a seventh hydraulic suspension cylinder, an eighth hydraulic suspension cylinder, a ninth hydraulic suspension cylinder and a tenth hydraulic suspension cylinder, and the third group of hydraulic suspension cylinders comprise an eleventh hydraulic suspension cylinder, a twelfth hydraulic suspension cylinder, a thirteenth hydraulic suspension cylinder, a fourteenth hydraulic suspension cylinder, a fifteenth hydraulic suspension cylinder and a sixteenth hydraulic suspension cylinder; the hydraulic loop AFand the hydraulic loop CG are connected to form a closed loop AF-CG through multiple-way directional valves, the hydraulic loop AF and the hydraulic loop BH are connected to form a closed loop AF-BHthrough the multiple-way directional valves, and the the hydraulic loop CG and the hydraulic loop BH are connected to form a closed loop CG-BH through the multiple-way directional valves; and the first group of hydraulic suspension cylinders are connected to the closed loop AF-CG, the second group of hydraulic suspension cylinders are connected to the closed loop AF-BH, and the third group of hydraulic suspension cylinders are connected to the closed loop CG-BH. According to the supporting system of the multi-group hydraulic suspension oil cylinders of the tire type crane, the load balances ofall the hydraulic suspension oil cylinders are kept to be unchanged, any set of tires are made to not be overloaded, and the troubleshooting ability is improved.
