ABSTRACT:
An unloader, for hauling vehicles such as pick-up trucks, which is functional also as a load cover, being essentially an elongated apron of material which is flexible, of very high tensile strength and having a low friction characteristic, as well as being quite thin so that it can be wound into a relatively small diameter roll by a manually operated winch roller removably mounted on the rear end of the vehicle. When used as a combined load cover and unloader the winch roller is mounted on the vehicle near the top rear edge of the load-receiving box, extends forwardly along the bottom of the box so that the load, which is usually amorphous material, may be placed in the box and onto this part of the apron, a second part of the apron of the same width being returned rearwardly over the top of the load material to a winch roller to prevent the load material from being spilled or blown away in transit, unloading being accomplished by operation of the winch roller, generating a combined rearward tumbling and conveying action on the load material and the deposition thereof at the rear end of the hauling vehicle.
