How is this accomplished? You can't use traditional drives at the head, the tension would be too high and it would snap the belt. Are they using powered idlers?

I wonder if it might be a conveyor belt WITH a full length cable running beside the conveyor belt to drive intermittent idlers along the way. Cable would probably be cheaper than 122 miles of drive chain and sprockets.

There is a huge abandoned conveyor system in Navajo country. We drove past the end of it earlier this year in Northeast Arizona. For 50 years, it moved coal 17 miles to a point where it was loaded on rail cars to be moved to the power plant in Page, Arizona. The last loads were hauled last year.
