Its tub is constructed of AR-400 steel or equivalent steel, with a Brinell hardness of 400. This means that, while the TKSSD is versatile enought to handle sand, gravel and crushed stone, it also has the strength and abrasion resistance to handle shot rock, demolition, rip rap and other abrasive loads. And with Trail King's full-depth frame, it has a load capacity of up to 60,000 pounds.

But the TKSSD isn't just built tough and strong, it's engineered smart, too.

For instance, the round-bottom tub design with angled corners delivers faster, cleaner, "no-stick" dumping from either side. Also, the lateral supports of the tub are incorporated into the one-piece, flame-cut end caps in such a way that no additional gussets or welding are required - providing both strength and durability. Then there's the larger bearing surface at pivot points, the secure tun lock-down system, and many other standard and optional features that make sense for a wide variety of aggregate hauling applications. What's more, the TKSSD is backed by Trail King's network of dealers, known nationwide for outstanding sales and service.
