Maxon Industries Inc.

The name Maxon has been associated with the concrete industry for over 70 years. The evolution of Maxon equipment began in the 1930s when Glen Maxon Jr. went to work for T. L. Smith Company to develop more uniform and quicker concrete mixing with tilt mixers for the Tennessee Valley Authority. In the 1940’s he developed and was awarded a patent on the Plastigraff, a means of checking the slump inside a tilting central mix drum by measuring the resistance of concrete against the paddles inside the mixer. A series of lights outside the machine indicated the slump, or workability of the concrete. During the 1940s he formed his own company and designed the Dumpcrete, a non-agitated rear dump haul body. The patented unit utilized a high discharge point to allow the carrier to chute concrete. At the same time, he started Expressway Mixers, offering the first portable central mix plants. As an active member of ACI and ASCM, he submitted papers on concrete plants and concrete mixer blade designs in drums. After World War II he developed the idea of central mix concrete and hauling in non-agitating carriers. Air intrained concrete became the standard, which allowed concrete to be carried short distances without segregation. Glen Maxon Jr. was referred to as the “Father of Central Mix Concrete” because of his knowledge and development of mixing, hauling and placing central mix concrete.
