The Savage Companies has sold its manufacturing facility, Savage Manufacturing Co. in Pleasant Grove, to Mack Trucks Inc., a leading manufacturer of heavy-duty diesel trucks.

Terms of the transaction, effective Feb. 1, were not disclosed.Mack Trucks Inc. will continue production of a front-discharge cement mixer developed by Savage Manufacturing in 1983. The mixer features a mid-mount engine and tandem steering, and was designed by Savage to comply with anticipated changes in federal laws regarding weight, length and carrying capacity.

Savage decided to sell its manufacturing arm last April to focus on its principal business of materials handling, said Allen B. Alexander, president of the 42-year-old Utah-based firm. "We recognized we had a great truck but (that) we're not manufacturing people," he said.

"We don't usually sell our companies. This is like putting up your kids for adoption. But, I think it will be great for the employees. It provides continued, long-term jobs with reasonable wages and benefits."

Mack Trucks Inc. will establish a separate Utah subsidiary that will increase Savage's current annual production of 60 cement mixers to 150, and possibly as many as 300 per year in the future. Savage employs 75 workers at the manufacturing facility, and it is likely that additional employees will be hired to meet increased production demands.

The Pleasant Grove business will be Mack Trucks' only Western facility. The company's principal manufacturing and assembly plants are located in Pennsylvania, North and South Carolinas, New Jersey, Maryland, Australia and Canada. The newest of those facilities was opened in 1987 in Winnsboro, S.C., and has a production capacity of 70 trucks per day.

"They want to (become) known as a Western industry," Alexander said. "The company was impressed with the environment and the people and wanted to come here."

John B. Curcio, president and chief executive officer of Mack Trucks Inc. met with representatives of the state, Pleasant Grove City and The Savage Companies Wednesday at the Little America Hotel in Salt Lake to announce the sale.

The sale of the facility to Mack Trucks Inc. will provide stable, steady production jobs for Utah County residents in a "good, clean heavy manufacturing industry," Alexander said.
