The hand-push cold spray marking machine is a high-pressure equal-flow type airless spray machine. The machine uses a gasoline engine to drive the hydraulic system to drive a single plunger pump, so that the paint forms a high pressure in the machine for spraying. The thickness of the marked line is uniform and the edges are neat. The spray gun frame guide rod lifting design makes it accurate and convenient to adjust the spray width. It has the characteristics of low labor intensity and quick and convenient construction.
