The invention discloses a multi-mode steering hydraulic control system. In the system, a flow distributing and collecting valve and an electromagnetic reversing valve are combined, the flow distributing and collecting valve distributes flow of a hydraulic source according to a certain proportion and provides energy for the steering system, and the electromagnetic valve controls the flow direction of a hydraulic oil circuit, so that front and rear groups of steering oil cylinders work according to a set requirement and drive wheels to rotate according to the operation intention of a driver to realize multi-mode steering. Compared with the prior art, the scheme has the advantages that: the front and rear steering oil cylinders are connected in parallel in an arbitrary steering mode, so that the problem of a high requirement on sealing property due to overhigh pressure of the front group of steering oil cylinders in the prior art is solved, and manufacturing cost can be effectively controlled; meanwhile, the hydraulic control system eliminates the influence of a circuit fault, and driving safety is ensured. On the basis, the invention also provides a wheeled crane using the multi-mode steering hydraulic control system.
