Highwall mining mining machine

Adaptable modular design Three high-tensile fabrications comprise the body of the Joy shearer, forming a slim main section with no under-frame. Eliminating the under-frame allows more material passage under the body, easier transport, quicker adaptation to different mining scenarios, efficient rebuilds, easier maintenance. Rigorously tested gear design Be confident your shearer will offer outstanding reliability. Ranging arm and haulage gear trains consist of robust spur gears incorporating decades of experience. State-of-the-art gear design software and meticulous load-testing help make the Joy shearer even more reliable. Haulage sections built to exacting standards Primary haulage gear case contained in a frame mounted to both sides of controller case. Inside the gear case are straight-cut spur gears manufactured to exacting standards. 7LS shearer can match tractive effort increase delivered by higher power-density motors. Custom-designed drums Experience the difference custom-designed drums can make for your operation. Using a three-axis digital lacing machine to manufacture custom-designed drums results in precise bit locations and angles. Final machining is accomplished with CNC turning centers to achieve precise fit. Choose the best Cowles blade for your site Equip your shearer with “T” style or “D” style Cowles blades. More compact “T” Cowles blades may perform better in drum loading by allowing more free-flowing material. Wider “D” Cowles blades are stronger, can take more abuse in harsh conditions.
