The invention relates to wheel-foot composite mobile mechanical equipment and a hydraulic system thereof. The hydraulic system of the wheel-foot composite mobile mechanical equipment comprises a hydraulic oil pump used for pumping oil under the driving of an engine, wherein an oil pumping port of the hydraulic oil pump is connected with a leg mechanism hydraulic cylinder and a walking wheel driving motor; the engine used for driving the hydraulic oil pump and comprising an engine water jacket and a pressurization system; a first cooling module comprising a first oil cooler, a radiator and a first cooling fan, wherein the first cooling fan is used for cooling the first oil cooler and the radiator; a second cooling module comprising a second oil cooler, an intercooler and a second cooling fan, wherein the second cooling fan is used for cooling the second oil cooler and the intercooler; the first oil cooler and the second oil cooler are arranged in parallel and are simultaneously communicated with hydraulic oil outlets of the leg mechanism hydraulic cylinder and the walking wheel driving motor. The radiator is communicated with the engine water jacket; and the intercooler is communicated with a supercharging system of the engine. According to the scheme, the problem that an existing hydraulic cooling system technology is high in development difficulty can be solved.
