The 12CM27 continuous miner, with a solid-head cutting head system, features a 965 mm (38 in.) conveyor width for standard width entry applications. The 12CM27, as well as all 12CM series continuous miners, are designed specifically to make efficient use of the additional space available in higher seam heights by offering improved outboard access to all major components.
The 12CM27 is a high-voltage machine (2300V 60Hz (3300V 50Hz)) that provides the ability to transmit more power through a given cable size. Reduced thermal losses in the cutter motors and trailing cables increase the available cutting time almost indefinitely, improving your production levels. The high-voltage capabilities mean that the 12CM27 is typically operated well within its maximum operating limits, which leads to longer motor and electrical component lifespans, reduced maintenance, and lower repair costs.
The 12CM27 includes our patented Optidrive AC traction system, which is coupled to a compact, all-gear transmission to provide smooth, reliable service. The cutter motor feedback and the traction differential features optimize sump performance even in the most demanding applications. Finally, the brushless AC traction motors are highly reliable and require minimal maintenance.
