MAXON Corporation, also known as Maxon Industries, is divided into four product divisions, that include Maxon Concrete Transportation Equipment, Maxon Environmental Solidification Equipment, Parsons Trenchers & Cable Plows and Seaman, Rex, & Pettibone Soil Stabilization Equipment. MAXON equipment began in the 1930s when Glen Maxon went to work for T. L. Smith Company to develop quicker and more uniform concrete mixing with tilt mixers for the Tennessee Valley Authority. In the 1940s, Maxon was awarded a patent on his development, 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; 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.
