The JOY continuous miner product line has been developed to meet the high productivity requirements of today's underground mining industry. Machine designs are available to satisfy the full spectrum of seam conditions for today's market.

The basic elements of each continuous miner are similar in design, following field proven philosophies perfected by Joy over the years. Each machine employs Joy’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.

The continuous miner product range is segmented by mining height requirements into three machine classes for low, medium and high-seam applications. Although the features vary for each machine in order to maximize productivity and reliability in a given seam, these features have in common basic design principals that put JOY machines on the leading edge of underground mining technology and produce the lowest cost per ton to the customer.
