The invention discloses a three-portal oil circuit of a forward piling car. The thee-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, a middle cylinder, and left and right tilting cylinders; rising, forward and tiling handles are arranged on the multitandem valve, and an oil inlet, an oil outlet, a lifting oil outlet, 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 connector 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, the side cylinder and the middle 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 three-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, the middle 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.
