Underground Mining Equipment


No two underground operations are the same—what, how and where you mine are unique. So we don’t offer one-size-fits-all solutions. Our underground systems are designed specifically for hard rock, as well as for longwall operations. We’ll even customize products to fit your mine. If you want equipment that’s built to stand up to demanding underground conditions—while delivering the productivity and cost per ton you demand—we’re there to tailor a solution.
