Abstract: A system for heating a dump body is provided. The system may include a diverter, a controller, dump body ductwork, and a first temperature sensor. The diverter may be configured to direct exhaust to an exhaust stack conduit, to a dump body conduit, or both, based on a position of the diverter. The controller may be configured to control the position of the diverter via an actuator. The dump body ductwork may be configured to receive exhaust from the dump body conduit and provide heat from the exhaust to the dump body. The first temperature sensor may be configured to provide a first measurement of temperature of the dump body or a payload of the dump body to the controller. The controller may be configured to control the position of the diverter in a non-binary manner based on a comparison of the first measurement of temperature with a target temperature or a target temperature range. A method for controlling exhaust distribution to dump body ductwork is also provided.

Abstract: Improved tailgates useful, for example, with dump beds or bodies of trucks. In certain example embodiments, tailgates capable of operating in multiple modes. In preferred (but not all) embodiments, tailgates capable of being selectively operated in metering, high lift, and non-lifted, pivot modes.
