In western PA during the late 70’s around the Clarion area, Draglines like these were like cellphone towers today. You get on a good hilltop you would use all your fingers and toes to count them all.
Another nice paint job and clean machine. I think this might be the largest tracked dragline I have seen on youtube. The boom looks like it might be close to 300 feet. I like the looks and smoothness of operation, considering the strata of rocks. Rocks are giving it a tough time. They would really tear up a bucket wheel.
