A device for unloading a live floor bulk material hauling vehicle which includes a feeder that collects bulk material being dumped from the vehicle by action of the live floor and moves the material onto a conveyor. The conveyor accepts the material from the feeder and conveys it outwardly from the vehicle to a desired location. The conveyor is pivotably attached to the vehicle and can be pivoted to a first position whereby the vehicle can be unloaded by operation of the live floor and the conveyor, and a second position whereby the conveyor is displaced sufficiently from the vehicle that the vehicle can be unloaded by operation of the live floor without operation of the conveyor.
