Abstract: A side tipper system for a vehicle includes a container for carrying material and selectively discharging carried material. The container includes a container body defining an upper portion of a first side wall, a second side wall opposing the first side wall, and a pair of opposing end walls; a floor pivotally coupled to the second side wall; and a side door pivotally coupled to the floor and defining a lower portion of the first side wall in a closed position and forming a discharge opening in an open position. The system further includes end assemblies configured to be mounted to a vehicle chassis at respective ends of the container, each end assembly operatively coupled to the container for supporting the container and for controlling discharge of material by: moving the side door from the closed position to the open position; and lifting the container body relative to the chassis.
