It is a machine that excavates rocks and ore.
Road headers run freely with a crawler and excavate rock and ore with a rotating hemispherical drum, which has cutting chips arranged on the surface. The drum is attached to the tip of a retractable boom mounted in front of the road header and can freely swing from side to side or up and down.
These road headers are also called free-section excavators.
