Show Giant Electric Shovel Can Scoop Up Freight Carload Some of the most powerful electric elec-tric equipment ever designed for mining purposes is being manufactured manufac-tured for -use at the new open pit coal mine near Jasonville, Ind. When completed, it will be installed in-stalled in one of the world's largest mining machines, a 25-cubic-yard dragline. According to engineers, this dragline will be so mammoth that, if it were placed atop a 12-story 12-story building, it could dig at ground level and could pick up in one scoop a load that would fill a freight car. Weight of the huge mining machine ma-chine will be 2,410,000 pounds. In operation op-eration it will be able to step off T,i feet at one stride, zig-zag between be-tween working locations, sidestep at any angle and travel over soft and irregular ground. Direction may be changed simply by swinging the machine's revolving frame. Without advancing its base it will be able to dump a load a block away. Totalling the equivalent of approximately ap-proximately 700 horsepower, the electric equipment under construction construc-tion includes the latest type of am-plidyne am-plidyne control, as well as two large motor - generator sets. Installed, it will make possible open-cut mining at the unusual depth of 40 to 70 feet. Open-pit operations at the Indiana mine employing the machine are expected ex-pected to begin about September 1. To be known as the Linton mine, number 28. it will have a monthly capacity of 60,000 tons of bituminous l coaL |
