Mokena, IL based Ozinga Brothers, which delivers concrete throughout the Chicago region and northern Indiana, plans to convert its entire fleet of 500 ready-mix trucks to run on CNG by 2020. The company will operate 112 CNG ready mixer trucks by year's end, up from 82 now, probably the largest fleet of CNG ready mixers in any fleet in the country today. Ozinga operates two ready mix truck configurations: front discharge Oshkosh tractors, and rear discharge Kenworth tractors. In their CNG configurations, both are outfitted with Cummins Westport's 8.9 liter ISL G engine. The company's fleet also includes 25 CNG fueled support vehicles.
