Heritage meets innovation for mid- to high-seam productivity

Engineered for reliability in mines running continuous haulage or cutting higher percentages of rock. Designed for narrow entry and high seam applications. Solid cutting head system and 965-mm (38-in) conveyor width. Available as a high voltage machine.

  • 40% more cutting power*
  • 20% more mass*
  • Up to 50% more productive*
  • *compared to 12CM12/15

Features and benefits

High production

With increased mass and immense cutting power, the 12CM27 is engineered to be the most productive continuous miner in the Joy lineup.

High cutting height

For use in thick seams with the ability to cut up to 5 meters (197 in).

High voltage option

For exceptional performance capability, the 12CM27 can be supplied at 2,300 volts or 3,300 volts to mitigate voltage drop issues over long cable runs.
