  • 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.
    Type: Grant

  • Pipeline air pocket detection system
    Patent number: 6375432
    Abstract: A method of detecting an air pocket in a concrete pump and minimizing the effect of the nozzle and boom reaction as the air pocket reaches the end of the boom. The hydraulic pressure of the pump is monitored to determine when a pump stroke contains air. Upon detection of air in a pump stroke, an alarm is sounded and the pump is slowed to minimize the effect of the air pocket when it reaches the nozzle of the boom.

  • Automatic leveling system for articulated boom
    Patent number: 6351696
    Abstract: An automatic leveling system for a vehicle supporting an articulable boom system. The automatic leveling system uses a microprocessor to monitor various inputs indicative of the current position of the vehicle and generates electrical drive signals to control the amount of extension of various outriggers extending from the vehicle.
