The present invention relates to a rollover prevention device of a specially equipped vehicle using a double check valve, which can measure a support reaction force of an outrigger by measuring only a pressure of an elongated portion of a cylinder. The rollover prevention device of a specially equipped vehicle using a double check valve includes: a cylinder with a piston inside, wherein the cylinder includes an elongated portion capable of being filled with fluid at the upper portion of the piston and a compression portion capable of being filled with fluid at the lower portion of the piston; a first flow passage connected to the elongated portion and communicating with the elongated portion; a first check valve disposed on the first flow passage; a second flow passage connected to the compression portion and communicating with the compression portion; a second check valve disposed on the second flow passage; a first pressure sensor capable of measuring a flow passage pressure of the first flow passage; and a third flow passage branching from the first flow passage and connected to the second check valve.
