Most mines try to increase production by adding bigger trucks or bigger machines. But one simple thing affects output more than people think. Excavator swing angle. 45° swing → 126% output 70° swing → 100% output 130° swing → 77% output 180° swing → 70% output Every extra degree means more swing time, more fuel burn, and fewer cycles per hour. Good mines design loading areas so trucks sit close to the excavator and keep swing angles around 60° to 90°. Small change in positioning. Huge impact on production.
