The invention discloses a dual-portal oil circuit of a forward piling car. The dual-portal oil circuit comprises a pump station, an oil tank, a multitandem valve, a steel pipe, an oil pipe, a forward cylinder, a side cylinder, and left and right tilting cylinders; a rising, forward and tiling handle is arranged on the multitandem valve, and an oil inlet, an oil outlet, a lifting oil port, forward oil inlet and outlet, and tilting oil inlet and outlet are formed under the multitandem valve; a pump station connector is arranged on the pump station and an oil return port is arranged on the oil tank; the pump station joint is connected with an oil inlet pipe, a connector and the oil inlet; the oil return port is connected with an oil return pipe, a connector and the oil outlet; the lifting oil outlet is orderly connected with a connector, the oil pipe, the steel pipe and the side cylinder; the forward oil inlet and outlet are connected with connectors, the oil pipe and the forward cylinder, respectively; the tilting oil inlet and outlet are connected with connectors, the oil pipe, the steel pipe and the left and right tilting cylinders, respectively. According to the dual-portal oil circuit of the forward piling car, the hydraulic oil is sucked out of the oil tank by use of the pump station and finally goes into the forward cylinder, the side cylinder and the left and right tilting cylinders to drive corresponding piston rods to stretch; the whole oil circuit is simple in structure and convenient to assemble.
