Rock Excavator Cut Its Teeth in Alaska

September 28, 2010

The IronWolf Crusher was developed originally to excavate Alaska's solidly frozen soil, but is finding wide application in rock excavating. The IronWolf system consists of a massive cutter head mounted on the front of a host machine, and a huge hydraulic power pack attached at the rear of the host machine. The machine's up-cutting drum fractures rock, cups the shattered pieces in spaces created by four of the drum's teeth, then slams the rock into breaker bars positioned in the drum's housing. The manufacturer, Construction Technology Inc., claims that 4-inch-minus material results.
