12HM and 14HM series
The basic elements of each continuous miner are similar in design, following field-proven philosophies perfected by Komatsu over the years. Each machine employs Komatsu’s multi-motor concept with outboard access to motors, gearcases, controllers and other major components. The philosophy calls for the isolation of major components for easier troubleshooting and maintenance. The continuous miners use individual motors with direct drive transmissions to power the cutter, traction, gathering and hydraulic systems. This permits service or repair quickly and easily, thus reducing downtime and maintenance costs.
