Boom-type roadheader, also known as partial section roadheader, is an efficient combined operation machine that integrates cutting, walking, shipping, spraying and dust suppression. When working, the cutting head mounted on the cantilever swings up and down, and can cut tunnel sections of any shape, so it is also called an arbitrary section tunneling machine. It can be applied to tunnel construction of subway, municipal, highway, water conservancy, etc.
