Sandvik MF420 crawler-mounted borer miner is the world's heaviest and most powerful continuous miner. It is specially engineered to cut and deliver material to the rear of the machine in a single continuous operation. This heavy-duty continuous miner is used to drive entries and headings and mine rooms as fast as haulage equipment can remove material to the main haulage.
