U-Through Bin Unloading

U-Trough Bin Unload


GSI U-Trough Unloads are available for bins up to 60 ft. diameter, 5000-6000 BPH*. The U-Trough fits under most standard aeration floors and requires minimal assembly. It features an adjustable flight for easy expansion to the outer wall, dual action sweep wheels that move the unloader through the grain while sweeping out outer sidewall grain, and enhanced design to help sustain grain quality. Constructed from top quality galvanized material and components, the GSI U-Trough requires minimal maintenance and will provide years of reliable operation.
* Capacities may vary depending on grain type and condition.

Power and Performance
The drive wheel (patent pending) sweeps grain from the bin wall as it propels the unloader providing aggressive sweep action, even in severe conditions. The sweep wheel utilizes a speed reduction gear which adjusts the speed of the wheel (40-1) to better control unload at the sidewall.

Flexibility and Convenience
The sweep length is adjustable to accommodate various bin sizes. Standard size sweep is 7.25″ on U-Trough systems. A sweep stop* can be controlled from outside the bin to limit the sweep to one revolution around the bin.
* Stirators may require modification.

Sweep Drive Options
Gearbox Sweep Drive – Features a fully enclosed shifting mechanism with no chains in the gearbox. Food grade oil is used to assure no bin contamination. One motor drives the unloader and sweep from outside the bin.

Extra Long Center Gate – Designed for maximum grain flow. (maximum length of exposed flight on the intake translates into maximum unloading capacity).

Electric Powerhead with quick detach motor mount and over center belt tensioner. A rubber gasket on the belt guard maintains tube pressurization for a positive airflow seal. Incline Elbow elevates the discharge to a fixed angle, 20” lift from center discharge to ground.
