Sandvik roadheaders are advanced, self-propelled, extremely powerful rock-cutting machines designed to excavate roadways, tunnels and chambers continuously without using explosives. Powered electro-hydraulically, they emit no fumes and are used extensively in coal mining, mineral mining and underground construction projects, where their ability to excavate the desired profile without causing harmful vibrations is highly valued for both environmental and safety reasons.
The roadheader family also includes separate, multi-purpose hydraulic cutting heads for mounting on excavators.

Former name: Alpine Miners
Sandvik MR-series roadheaders for mining are equipped with powerful, geometrically optimized, transverse cutter heads proven to give the best cutting performance in a wide range of rock formations. Mounted on an extremely robust hydraulic boom (telescopic on some models), they are a rugged, reliable, highly productive solution for both development and direct production duties. |  |
