  • Concrete mixer and controls therefor for controlling drum rotation
    Patent number: 10744676
    Abstract: A concrete mixing system includes a vehicle, a rotatable mixing drum coupled to the vehicle, an incline and/or slump sensor, and a controller. The controller is configured to effect a change of rotational speed of the rotatable mixing drum in response to a signal from at least one of the sensors indicating an increased likelihood of spillage of concrete from the rotatable mixing drum.
    Type: Grant
    Filed: September 16, 2016
    Date of Patent: August 18, 2020
    Assignee: Schwing America, Inc.
    Inventors: James Dickerman, Carl Phillip Quist, Gary Heidger, Clinton Martinez, Daryl Roehrich, Eric Seelnacht, Dang Thieu, Scott Roisum

  • Automatic drum rotation control concrete transit mixer truck
    Patent number: 7722243
    Abstract: A concrete transit mixer truck includes a control system that automatically controls rotation of the mixer drum at a constant drum speed when the mixer truck is traveling. When sensed speed of the truck exceeds a threshold, the control system automatically causes a hydraulic system to rotate the drum at a constant speed, regardless of the truck engine speed.
