This five piece unloader kit is easy to build and can be completed in one evening. It consists of polyurethane and brass parts. All that you need to build it is some adhesive (we like CA), an X-Acto knife, some fine sandpaper and black paint. For a view of the general purpose tires or spoked metal wheels that are available, take a look at our Small Coal Conveyor. Please specify which type you desire. Our unloader kit is designed based upon research on coal handling systems for small coal operations and yard facilities that did not contain large coaling stations. See our listings for our large and small conveyors too.
