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.

Abstract: A mounting bracket is attachable to a vehicle frame for pivotally connecting a booster axle assembly comprising a pair of spaced arms, each arm having a first end, a second end, and an axle connected therebetween. The mounting bracket includes a U-shaped portion having a base and a pair of spaced legs connected to the base and extending in a first direction generally normal to the base. The pair of spaced legs and base define a space for receiving the first end of one of the arms of the booster axle assembly. Each leg defines first and second spaced appendages that define a slot. A mounting plate is connected to the base of the U-shaped portion and extends in a second direction normal to the base to permit connection of the mounting bracket to the vehicle frame.

Abstract: A silo for storing viscous material such as sludge, the silo comprising a floor and a perimeter wall connected to the floor, is disclosed. The silo further comprises a moveable frame adjacent to the floor wherein the frame defines an area less than the area of the floor, and an opening in the floor. A crosspiece having opposite ends mounted to generally opposing portions of the perimeter wall is provided within the silo adjacent to the moveable frame. The crosspiece contains a surface facing the floor and is positioned adjacent to the frame. The crosspiece further comprises one or more diverter portions connected to the crosspiece which extend from the floor facing surface of the crosspiece towards the floor.

Abstract: A fire fighting vehicle having a boom system includes a working assembly attached to an end portion of the boom system. The working assembly comprises a frame pivotally mounted at a midpoint of the frame to the end portion of the boom. The frame carries a mechanical actuator that is connected to a tool capable of piercing an exterior of a structure when the mechanical actuator is actuated.

Abstract: An anti-rollover system is used with a concrete mixing truck with a mixing drum, in particular during turning maneuvers, for preventing rollovers by the truck. The anti-rollover system is comprised of one or more sensors on the truck which generate an input signal representative of the truck's operating conditions indicative of a rollover condition. The system compares the sensor signal against stored data indicative of rollover conditions and if necessary initiates corrective action to prevent the truck from rolling over. Corrective action includes stopping, or in some circumstances slowing, rotation of the drum carrying a concrete load. With mixing trucks including a booster axle system, corrective action may additionally or separately include unloading the booster axle.
