- Abstract
The article focuses on Model 21 electric shovel produced by Marion Steam Shovel Co. as the first small excavator suitable for general construction applications powered by electricity and the most successful electric excavator in terms of units sold. Topics discussed include Model 21's use of an independent drive system, 5-motor design which was more efficient than single-motor drive and better suited for a shovel's intermittent operations and the restoration of Model 21 by Museum volunteers.
