A conveyor for loading items into a trailer, the conveyor comprising a transport surface with a discharge end and a receiving end, a belt or rollers on a top side of the transport surface that transports items over the transport surface, and a wheel assembly coupled to a bottom side of the transport surface at a distance of approximately L from the discharge end of the conveyor, where the distance L is approximately 75-88% of the length of the trailer. Embodiments of the invention may be used to safely transport items to and from a drop-frame trailer with a trailer conveyor assembly that is mounted on the bottom interior surface of the drop-frame trailer. Some embodiments of the invention may further comprise an obstruction sensor mounted on at least one of the bottom side of the transport surface between the wheel assembly and the discharge end of the transport surface, or on the discharge end of the transport surface.
