Drive-Over Unloaders

The low 3’ profile of the 48” Low Pro delivers the convenience, efficiency, ease-of-use and environmentally friendly characteristics your operation demands. The drive over truck unloader provides an efficient solution for unloading material where you need it. The low profile means you’ll reduce set-up time by building smaller earthen ramps, cutting your labor needs and fuel costs.

Required Running Horsepower (Headshaft)	HP

Drive efficiency needs to be taken into consideration to determine the motor HP required. This can be an additional 10-15% above the headshaft HP. The ability to start a loaded conveyor will also require additional HP consideration.

Horsepower calculations based on 350 fpm conveyor speed.

Recommended Belt Width	inches

Fines are defined as material with a size that is less than 10% of the maximum material size of the sample.

Belt width recommendations are based on a belt speed of 350 fpm and 80% of maximum volumetric belt carrying capacity.

Capacity is based on a material density of 100 pounds per cubic ft, 37.5 degree angle of repose material and 3-roll, 35 degree idlers.
