AFC Drive Systems
The JOY Turbo Transmission Technology (TTT) drive system provides the simplest, most reliable high torque starting capability for large AFCs at the lowest operating cost. The JOY TTT provides trouble-free, repeat starting of the AFC to ensure continuity of production.
Joy designs and manufactures a complete range of stageloader crushers. Designed for difficult conditions, these units can efficiently crush lump coal and oversize rock for easier conveying and improved system productivity. JOY crushers have proved to be extremely rugged and trouble free with little maintenance required.
All JOY crushers incorporate a frame fabricated from heavy steel plate and strengthened by heavy ribs for maximum rigidity. Easy access to the crusher roll is provided through an inspection door in the top of the frame. To suit customer preference, JOY crushers are available in a direct gear-drive model or a V-belt drive.
Joy manufactures stageloaders for excellent reliability and high availability by using heavy duty components, including heavy pan side sections and high impact resistant flight bars. High capacity, custom built JOY stageloaders move continuously with the longwall and provide the necessary overlap to suit mining conditions.
