Introduction of EBZ Boom Type Roadheader

EBZ Series Roadhader, also known as boring machine, is a boom-type road header machine which widely used for tunneling and coal mining.

Roadheader is based on the producing situation of middle, mini coal mines. This model has reliable performance, simple structure, small size, light weight and easy transportation.

As a roadheader for coal and coal road, this machine adopts small-diameter cutting head and numerical technology, improving the teeth structure, so it has bigger power and stable working performance. Also it increases the ability of breaking rocks and passing the faultage.
