The invention provides an axle centering control system and a crane, which relate to the technical field of engineering machineries. The axle centering control system comprises a reversing valve, a centering cylinder and a hydraulic oil control assembly, wherein an oil inlet of the reversing valve is connected with an oil inlet branch, an energy accumulator is arranged on the oil inlet branch, andan oil outlet of the reversing valve is connected with the oil tank. A port C of the centering oil cylinder is connected with a working port of the reversing valve, and a port T of the centering oilcylinder is connected with the oil tank; the hydraulic oil control assembly comprises a pressure sensor and a controller, the pressure sensor is used for collecting hydraulic oil data of the energy accumulator and transmitting the hydraulic oil data to the controller, and the controller receives the hydraulic oil data and controls the hydraulic oil pressure of the energy accumulator according to apreset value. The crane comprises an axle centering control system. By means of the axle centering control system, the technical problems that in the prior art, a hydraulic system cannot monitor hydraulic oil pressure information, hydraulic oil losses are possibly caused, and vehicle driving safety is harmed are solved.
