My question is the same Jim. But, if you think about it, when the cable dips down or up it goes off center pulling on the wheels rather than the rollers.
Watch some of Bennett Shovels Lima 2400 videos. That machine has the same type as this B-E one. I think the reason for this type is because on these smaller machines the drag cable is whipping around way more than the giant dragline's ropes. Translating into more wear so the load is transferred into both sheaves. The large machines have more space to put larger diameter sheaves on turning slower lasting longer.
