Attempts to purchase and preserve the shovel from Consol to make it the centerpiece of a mining museum exhibit for $ 2.6 million fell short.

Knee action design made possible the largest shovel ever built, increased digging power, allowed the bucket to move horizontally into the cut and improved swing efficiency, distance, and radius.

Dug 315,000 lb (143 metric tons) of earth in a single bite, swung 180°, and deposited the load up to 390 ft (119 m) away from the digging points at heights up to 140 ft (42.5 m).
