Roadheader Cutter Welding

Roadheaders Designed For Continuous Excavation

Sandvik roadheaders are equipped with powerful, geometrically optimized cutter heads, which are designed to continuously excavate roadways, tunnels and other underground caverns without using explosives. These electro-hydraulic machines cause no harmful vibrations and are ideal for mining coal and other soft rock minerals as well as for developing tunnels in ore mines.

Roadheader Wikipedia
