Armstrong Coal Co. now owns three Page draglines-one now operating at the Midway Surface mine, one due to go into operation at the Equality surface mine and a third that is being rebuilt also for use there. Armstrong is banking on the economics of scale to once again prove that these older machines are still the most efficient way to move large volumes of overburden. 4 photos.
