A disclosed safety device for an arm roll truck comprises: a striker installed on the front side of a gantry; and a latch means installed on the rear side of an outer arm. When an inner arm is extended while the outer arm is level with the gantry, a latch means is elastically fixed to the striker and fixed to the gantry so that the outer arm does not rotate. When the inner arm is contracted, the latch means contacts the rear of the inner arm and pressurizes the outer arm to rotate. The present invention enables the outer arm to be fixed to the gantry when dumping an arm roll box, and can release the outer arm fixed to the gantry when the arm roll box is put down on the ground.
