KOEHRING Dollars put into highway improvement are best invested when the concrete is manufactured by the Koehring remixing principle intermingling the cement, sand, stone and water into a uniform concrete and depositing it on the grade by the Koehring boom and bucket distributing system. The five distinct mixing actions of the Koehring drum mean greater strength concrete or the same strength of concrete in less mixing time. BUT The Koehring Machine Company is not satisfied to manufacture simply a mixer that gives the greatest strength concrete, it builds a machine with individuality in each part that is designed to do the special work for which it is sold.
