A road header is a heavy duty machine used primarily in tunnel construction and mining operations. Featuring a rotating cutting head mounted on an articulated boom, it efficiently excavates rock, soil, or other materials to create tunnels, roadways, or underground spaces. Equipped with cutting tools, the cutting head breaks and removes material while crawler tracks or wheels enable mobility across varied terrains.

Meet the roadheader! This powerful rock-cutting machine can work its way through 1,000 tonnes of rock daily—and with less noise and surface vibration than a more traditional tool like a jackhammer. They're used in tunnelling projects globally, and now, they're in Toronto to help build the Ontario Line. Learn more: https://bit.ly/3Em64A4 | Metrolinx
