Abstract: A front discharge transit mixer having an air spring associated with each wheel. A load sensing system senses the pressure in each air spring and is analyzed to determine a load at each wheel. The load at each wheel is compared to a predetermined load and the pressure is varied as needed to distribute the load to other wheels.

Abstract: A method and system operable with a front discharge transit mixer to facilitate multiple deliveries of concrete materials from a single batch of concrete material. The system includes an interactive weight system which is utilized by the transit mixer operator to quantify the amount of material discharged at each delivery point. The front discharge transit mixer has a plurality of fluid springs in which the pressure is sensed and thereafter interpreted to obtain the initial weight of the truck and concrete material prior to delivery of a first quantity of concrete. After the discharge of the first quantity of concrete, the pressure within the plurality of fluid springs is sensed and thereafter interpreted to determine the quantity of concrete remaining in the front discharge transit mixer. The discharging of concrete can continue with the determination of the quantity of concrete for each discharge.

Abstract: The present invention defines a transit mixer for the delivery of materials to a job site. The transit mixer has a charge hopper for receiving material therein and delivering the material to the mixing drum which forms a portion of the transit mixer. The charge hopper has an inlet that is stationary with respect to the vehicle chassis, and a tongue member that is pivotally coupled to the inlet portion. A powered cylinder is coupled between the inlet portion and the tongue portion for allowing the switching between a material charging state and a discharging state. The inlet portion and the tongue portion are in material communication with one another and upon actuation of the powered cylinder the distal end of the tongue position is moved relative to the inner surface of the mixing drum. Another aspect of the charge hopper is that in the charging mode the tongue extends beyond a pair of flights within the mixing drum.
