In the 1930s, iron mining expanded in Iron County and massive shovels were needed to excavate the needed ore. According to company delivery records, two Bucyrus-Erie 120-B shovels were delivered to the Utah Construction Company in Cedar City in September of 1936 for use in the iron mines. At the time, the hourly wage for a shovel operator was $0.48 per hour.
The electric 120-B shovel had a six cubic yard dipper capacity, big enough to scoop up six tons of dirt and rock, enough to fill a hole the size of a large pick-up truck with extended cab and bed. AC power was supplied to the shovel via a trailing 23,000 volt electric cable which drove a 275-horsepower motor-generator set. When moving the shovel from pit to pit, bulldozers were employed to prevent the huge tracks from slipping down the hill.
About 330 of the 120-Bs were sold around the world over a period lasting almost three decades. SHE (shovel excavator) 22 was used continuously until the 1970's. SHE-22 had previously been located west of town where it sat for many years. In 2012, in partnership with Utah State Parks, Cedar City, Iron County, Gilbert Development, Inc., and Construction Steel, Inc., the shovel was relocated to Frontier Homestead State Park.
