The Power of Engineering: The 50 Cubic Yard Electric Shovel at the Georgetown No. 12 Mine

In the world of coal mining, the Georgetown No. 12 Mine of the Hanna Coal Company was a massive operation, and at the heart of its success was one of the most impressive pieces of machinery ever built: the 50 Cubic Yard Electric Shovel. This massive machine played a crucial role in the extraction of coal by moving vast amounts of earth and rock overburden. The scale of this operation was awe-inspiring, and the technology behind it was a true marvel of engineering.

The Scale of the Operation

The 50 Cubic Yard Electric Shovel was capable of removing an astounding amount of material—up to 1,600,000 cubic yards (or about 2,400,000 tons) of earth and rock each month. To put this into perspective, if all of this material were loaded into open railroad cars, it would fill approximately 48,000 cars. This immense capability made the shovel an essential tool for coal mining operations during the early to mid-20th century, when the demand for coal to fuel the nation’s growing industrial economy was at its peak.

The Technology Behind the Shovel

At a staggering weight of 1,750 tons, the electric shovel was a true engineering marvel. Powered by 4,160 volts of electricity supplied through flexible cables, this massive machine was a powerful tool in the coal mining process. The electric shovel’s design allowed it to dig and move large quantities of earth with incredible efficiency, making it one of the most important pieces of equipment at the Georgetown No. 12 Mine.

The operation of the shovel was controlled by a single operator, who used a combination of foot treadles, hand levers, and a whistle cord to manage its various functions. This system allowed the operator to control the dipper, scoop up massive amounts of material, and transport it from one location to another within the mine site. The precision required to handle such a massive machine was remarkable, and the operator’s skill was key to the shovel’s efficiency.

The Importance of Mobility

In addition to the shovel’s digging and scooping functions, another key aspect of its design was its ability to move efficiently across the mine site. The electric shovel had a specialized control system that allowed it to relocate itself without the need for disassembly. This was a significant advantage in the vast open mining sites, where continuous operation was crucial to maintaining production.

The mobility of the electric shovel meant that it could navigate across the mine, repositioning itself as needed to reach new coal seams and remove overburden without losing valuable time. This capability allowed the machine to maximize its productivity and efficiency, ensuring that the coal mining operation could keep pace with the growing demands of the industry.

A Symbol of Industrial Power

The 50 Cubic Yard Electric Shovel at the Georgetown No. 12 Mine stands as a symbol of the industrial strength of its era. The scale of the operation and the technology involved in moving such massive amounts of material highlight the importance of heavy machinery in large-scale mining. These machines were critical in helping to fuel the growth of the coal industry, which in turn powered the nation’s economy during the early to mid-20th century.

The Georgetown No. 12 Mine and its electric shovel exemplified the power of innovation and the role of engineering in transforming industries. The shovel’s ability to scoop vast quantities of earth and rock with precision and efficiency made it an indispensable tool for coal mining operations. As a result, it played a significant role in the expansion of the coal industry, which was instrumental in powering the nation’s industrial revolution.

Conclusion

The 50 Cubic Yard Electric Shovel at the Georgetown No. 12 Mine is more than just a piece of mining equipment—it is a testament to the power of innovation and engineering. Its massive scale and efficiency revolutionized the coal mining industry, allowing it to meet the demands of a rapidly growing economy. The shovel’s ability to dig, move, and relocate efficiently helped shape the future of large-scale mining operations and left an enduring legacy in the history of industrial machinery.

The Georgetown No. 12 Mine and its electric shovel serve as a reminder of the technological advancements that defined an era and continue to influence modern engineering and mining practices today.
