Abstract
A dump truck having a dump body which includes a rotatable feedgate for adjusting the size of a passageway through a rear opening at the rear of the dump body. The rotatable feedgate is rotatably mounted within the rear opening to provide for improved control of the flow of materials within the dump body which pass through the rear opening when the feedgate is positioned into an open position. A side guide is incorporated into the rotatable feedgate to provide additional control of the flow rate of materials through the rear opening especially at low feed rates. The rotatable feedgate design includes a rotatable feedgate position for open mode hauling whereby the feedgate is repositioned in the rear of the dump body. An opening plate is also provided to be used to provide an alternative arrangement for sealing the tailgate opening while the rotatable feedgate is attached or detached from the dump body.
