The Load King 3528-3ST is a versatile, high-capacity side dump designed for operators who care about payload efficiency, stability, and long-term durability across a wide range of hauling applications. Its 28-yard tub, 50-degree dump angle, and robust push block deliver fast, controlled material discharge, while the air-ride suspension and lift axle keep the trailer compliant when loaded and economical when running empty. Built with high-strength steel and replaceable wear components, it’s engineered to stand up to abrasive materials without becoming a maintenance headache, and driver-friendly features like in-cab controls, an electric tarp, and sealed LED lighting make daily operation simpler and safer. The result is a side dump that works just as well for aggregates, site development, municipal work, and material transfer as it does for traditional heavy hauling -- reliable, efficient, and easy to live with.
