Abstract
In an embodiment, a device for increasing railcar capacity is disclosed. The device includes one or more augers that transfer and pack bulk materials into a railcar. In an embodiment, the one or more augers are compression augers. In another embodiment, the device includes two augers where one auger is a left-hand auger and the other auger is a right-hand auger. The left-hand auger and right-hand auger are mounted on a common shaft. The forces on the device arising from packing the railcar and compression of bulk materials by the one or more augers are offset by the common shaft. In an embodiment, one or more feeds supply bulk materials to the one or more augers. In another embodiment, the one or more feeds are feed augers. In another embodiment, the one or more feeds are feed belts. In another embodiment, the one or more feeds are feed drags. In another embodiment of the device provided, the one or more feeds transfer and pack bulk materials into a railcar.
