In 1970 Cobey bought Eagle Crusher back and restarted the company with one employee. As Cobey said, “I bought a name and some bad inventory.” Eagle slowly grew and in 1974 and 1975, purchased Diamond Iron Works and Austin-Western for their parts sales.
Cobey recruited his daughter, Susanne Cobey in 1974, becoming the company’s tenth employee to handle the parts sales. She had previously been with Ford Motor Company where she was the first, female, junior executive.
Through the 1970s and into the early 1980s, Eagle Crusher sales grew in the aggregate industry, but the company’s primary focus was the sale of portable coal crushers for strip mining. In 1983, the resolution of the coal strike caused portable coal crusher sales to virtually disappear.
Susanne Cobey sought a new direction for Eagle Crusher. She knew of the frustration customers were having processing asphalt and concrete with rebar with the traditional aggregate jaw and cone. She determined that the Horizontal Shaft Impactor (HSI), which was developed after WW II to process debris, was the answer. Susanne concluded that only one HSI style suited the US market. With that impactor, Eagle built the first US commercial recycling plant, Eagle’s Jumbo 1400, in 1984, and a new industry was born.
As Eagle Crusher’s own manufacture of a range of portable recycling plants progressed, the company found a need for a more innovative and robust impactor, thus in 1994, introduced its own line of a superior, UltraMax® HSI, featuring a unique, sculpted, solid steel, three-bar rotor, the industry’s heaviest, for the recycling market.
