The invention discloses engineering machinery and a hydraulic suspension system thereof. The hydraulic suspension system comprises an oil tank, a hydraulic pump, a first suspension oil cylinder, a second suspension oil cylinder and a reversing valve. Wherein the hydraulic pump is used for pumping a hydraulic medium in the oil tank; the first suspension oil cylinder comprises a first cylinder body and a first piston rod; the second suspension oil cylinder comprises a second cylinder body and a second piston rod; the reversing valve is provided with a first output port and a first input port; the first cylinder body is provided with a first inner cavity; one end of the first piston rod is inserted into the first inner cavity to divide the first inner cavity into a first rod cavity and a first rodless cavity; the second suspension oil cylinder is provided with a second inner cavity; one end of the second piston rod is inserted into the second inner cavity to divide the second inner cavity into a second rod cavity and a second rodless cavity; the first rodless cavity and the second rodless cavity are both communicated with the first output port. The engineering machinery and the hydraulic suspension system of the engineering machinery have the beneficial effects that the engineering machinery and the hydraulic suspension system of the engineering machinery are suitable for being used in complex terrain environments.
