Catenary shot blasting machine is a single stroke catenary continuous shot blasting cleaning equipment, it has static loading and unloading of workpiece, automatic rapid transportation and positioning, workpiece rotation shot blasting cleaning. The machine is controlled by conventional electric appliances and the conveying track of the workpiece is stepless. Suitable for large quantities, cast steel, cast iron, and welding parts of all-round shot blasting cleaning, used for various forms of hanging workpiece. Through shot blasting cleaning, not only can remove the rust on the surface of the workpiece, clean up the weldingslag on the structural parts, but also can eliminate the welding stress of the workpiece, improve the fatigue strength of the workpiece, increase the adhesion of the paint film when the workpiece is painted, and finally achieve the purpose of improving the surface and intemal quality of the whole workpiece. Widely used in metallurgy, petroleum, chemical, machinery and other industries.
