The Silver Spade

The Silver Spade was a giant power shovel used for strip mining in southeastern Ohio. Manufactured by Bucyrus-Erie, South Milwaukee, Wisconsin, the model 1950-B was one of two of this model built, the other being the GEM of Egypt. Its sole function was to remove the earth and rock overburden from the coal seam. 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, and the shovel was dismantled in February 2007.

The design is unusual, as it uses a Knee action crowd, and only these two Bucyrus-Erie 1950-B's were fitted with this technology. The technology was a requirement of the owners and had to be licensed from Marion Power Shovel, with Marion being allowed to use Bucyrus-Erie's cable crowd system in return.
