Wow, you know a lot about hoppers!
Creekside Manufacturing’s self-dumping hoppers are NOT pinless. Here’s why: we’ve spent considerable time and energy extensively evaluating pinless approaches, and thus far we have not been convinced that this approach is ideal for most customers. The pin in a traditional self-dumping hopper keeps the dumper on track as it pivots forward, and we’ve seen time-and-time again how the pinless approach creates multiple pinch points and ultimately failure points, creating durability issues in the long-run.
Proper self-dumping hopper manufacturing, with a traditional pin, requires attention to detail, skilled welding and planning, and experience to manufacture well. When built well, self-dumping hoppers like ours can last for decades.
