Our self-dumping hopper is engineered to allow a single person to quickly and efficiently empty the container. It’s the perfect attachment for moving and dumping scrap, trash, debris, concrete, sand, dirt, stone, or any other bulk material (available in watertight as well). Hoppers are made to roll forward when loaded, dump completely and then automatically return to the upright position so you can lock it in place and go again. The 3″ fork slots accommodate most forklifts and pallet forks.Don't waste money by buying it. Why can't you make it yourself?
