Marion Power Shovel Company designed, manufactured and sold steam shovels, excavators and dragline excavators for use in the construction and mining industries.
Founded in Marion, Ohio in August, 1884 by Henry Barnhart, Edward Huber and George W. King as the Marion Steam Shovel Company, the company grew through sales and acquisitions throughout the twentieth century. The company changed its name to Marion Power Shovel Company in 1946 to reflect the industry's change from steam power to diesel power. The company ceased to be an independent entity when it was sold, becoming the Marion division of Dresser Industries, Inc. in 1976. In 1992 Dresser spun off the Marion division and certain other assets into a holding company that would eventually become known as Global Industrial Technologies, Inc. Global put the Marion division up for sale in 1997 and Bucyrus International, Inc. purchased the division for US$40.1 million. Bucyrus integrated the Marion division's products into the Bucyrus product line, then closed the Marion, Ohio, facility.
Marion Power Shovel lives on as a brand owned by Bucyrus, which manufactures OEM parts and provides technical service for Marion branded machines that are still in use. Marion Power Shovel's historical corporate files and archives are split between Bowling Green, Ohio's Historical Construction Equipment Association and the Marion County Historical Society in Marion, Ohio.

Marion Steam Shovel Company

Marion Model 91, Culebra Cut, Panama Canal

The Marion Steam Shovel Company was established by Henry Barnhart, George W. King and Edward Huber in August 1884. While steam shovels had been made prior to this date in the United States, Barnhart persuaded Huber to financially back his design, which incorporated a stronger bucket support than other makes. Barnhart and Huber patented Barnhart's changes under United States Patent No. 285,100 on September 18, 1883. One element of Barnhart's design was the use of solid iron rods (hog rings) to support the boom of the shovel, which was stronger than simple chain.^{[citation needed]}

This Marion Model 91 shovel on display in Le Roy, New York is the only example known to exist. This shovel is included on the National Register of Historic Places.

This machine set the record in July 1908 for moving 53,000 cubic yards (41,000 m³) of earth in 25 eight-hour days after American project management began. Marion built large and small steam shovels for building contractors, railroads and the US Army Corps of Engineers who were building the Panama Canal at the time.^{[citation needed]}
A Marion Model 91, the type used at the Panama Canal, was listed on the National Register of Historic Places in 2008.^[1] Marion was most successful with the Model 20 series contractors shovels (see steam shovel).^{[citation needed]}
During the project Marion Shovels broke world records in amount of cubic earth moved within a given time frame (1908) and greatest amount (8-ton) lifted by a single bucket (1911).^{[citation needed]}
Marion also designed and built the NASA Crawler-transporter used to transport both the Saturn V rocket and later the Space Shuttle to the launch pad.^[2]
By 1911 90% of all large bucket steam shovels and draglines were produced in Marion Ohio, which was also the headquarters of Osgood Steam Shovel, Fairbanks Steam Shovel and General Excavating Corporation. (Competitor Bucyrus Steam Shovel was founded 15 miles (24 km) from Marion in nearby Bucyrus, Ohio; the company relocated soon thereafter to Milwaukee, Wisconsin after Bucyrus city officials refused to approve expansion plans for the company.)^{[citation needed]}
