Openpit mining is an extremely effective surface mining technique for extracting minerals coal and other useful materials that are covered by relatively thin overburden layers However it takes the right equipment to penetrate the surface rock and reach the underlying layer in a timely and efficient manner
With more than 1000 large mining machines operating around the world our equipment has proven to withstand the extreme conditions of openpit mining from dusty and dirty environments to severe vibrations to temperatures ranging from 50° C to 50° C Standard AC multidrive installations have been mechanically reinforced to make them suitable for the minor sector
